Referring to fig. 1, a disinfection system 100 according to an embodiment of the present application includes a condensing device 10, an air supply device 20, a disinfectant preparing device 30, and a humidity detecting device 40.

The disinfection system 100 of the present embodiment may be applied to a dishwasher, as well as to other devices adapted thereto.

The condensing device 10 refers to a device capable of condensing a gas to reduce the water content in the gas. Specifically, the condensing device 10 has a condensing channel 11, and the condensing device 10 is configured to cool the gas entering the condensing channel 11, so that water vapor in the gas is condensed, and finally condensed water is formed.

The air supply device 20 refers to a device capable of supplying air to the sterilizing water production device 30. Specifically, the air supply device 20 may include an air pump, and may also be a fan.

The sterilizing water preparing device 30 refers to a device capable of preparing sterilizing water. In an embodiment of the present application, the gas supply device 20 may supply the sterilizing water preparing device 30 with a gas required for preparing the sterilizing water.

In the embodiment of the present application, the condensing means 10, the gas supply means 20 and the sterilizing water preparing device 30 are sequentially connected to form a gas condensing circulation loop 50.

It should be noted here that the condensation device 10, the air supply device 20 and the sterilizing water preparation device 30 are communicated with each other through pipes.

Specifically, the condensing device 10 has a first air inlet 12 and a first air outlet 13, the air supply device 20 has a second air inlet 21 and a second air outlet 22, the sterilizing water preparing device 30 has a third air inlet 33 and a third air outlet 34, and when the condensing device 10, the air supply device 20 and the sterilizing water preparing device 30 are sequentially communicated to form a gas condensing circulation loop, the first air outlet 13 of the condensing device 10 is communicated with the second air inlet 21 of the air supply device 20, the second air outlet 22 of the air supply device 20 is communicated with the third air inlet 33 of the sterilizing water preparing device 30, and the third air outlet 34 of the sterilizing water preparing device 30 is communicated with the first air inlet 12 of the condensing device 10, so that gas circulation can be realized.

It should be noted here that the gas discharged from the third gas outlet 34 of the sterilizing water preparing device 30 is surplus gas generated during the preparation of the sterilizing water. The surplus gas discharged from the sterilizing water producing device 30 can be returned to the sterilizing water producing device 30 for reuse by the conduction of the gas condensation circulation circuit.

Further, the gas condensation circulation loop 50 is further connected in parallel with a gas condensation adjustment branch 60, one end of which is connected between the condensation device 10 and the air supply device 20, and the other end of which is connected between the sterilizing water preparation device 30 and the condensation device 10.

Specifically, one end of the gas condensation regulating branch 60 is communicated between the first gas outlet 13 of the condensation device 10 and the second gas inlet 21 of the gas supply device 20, and the other end is communicated between the third gas outlet 34 of the sterilizing water preparation device 30 and the first gas inlet 12 of the condensation device 10. That is to say, the gas condensed by the condensation device 10 can be returned to the sterilizing water production device 30 via the gas condensation circuit 50, or can be returned to the condensation device 10 via the gas condensation regulating branch 60.

The humidity detection device 40 is used for detecting the humidity of the gas discharged from the condensing device 10 to control the gas to enter the gas condensation circulation loop 50 and/or the gas condensation regulation branch 60.

Specifically, the humidity detection device 40 may detect the humidity of the gas flowing between the first gas outlet 13 of the condensing device 10 and the second gas inlet 21 of the gas supply device 20.

The control gas entering the gas condensation cycle 50 and/or the gas condensation regulating branch 60 means regulating the flow direction of the gas, specifically, when the control gas enters the gas condensation cycle 50, the gas discharged from the first gas outlet 13 of the condensation device 10 can be introduced into the second gas inlet 21 of the gas supply device 20, further enter the sterilizing water preparation device 30, and then return to the condensation device 10 to complete the cycle. When the control gas enters the gas condensation regulating branch 60, the gas discharged from the first gas outlet 13 of the condensation device 10 can be introduced into the gas condensation regulating branch 60, and then returned to the first gas inlet 12 of the condensation device 10.

Therefore, in the disinfection system 100 of the present application, the gas discharged from the disinfection water preparation device 30 can be condensed and dehumidified by the condensation device 10 through the gas condensation circulation loop 50, and under the detection effect of the gas condensation regulation branch 60 and the humidity detection device 40 which are connected in parallel with the gas condensation circulation loop 50, the gas can enter the condensation device 10 again to condense and dehumidify when the humidity after the gas condensation cannot meet the requirement, so that the humidity of the gas entering the disinfection water preparation device 30 can be reduced to be within the safe range, the disinfection water preparation device 30 is further protected, the service life of the disinfection water preparation device 30 is prolonged, and the disinfection water preparation device 30 can reliably operate.

In particular, in the embodiment of the present application, the sterilizing water preparing device 30 includes a discharging device 31 and a water tank 32, the discharging device 31 is used for discharging gas to electrolyze the gas to generate ozone substances, and water in the water tank 32 can be mixed with the ozone substances to form sterilizing water.

Since the discharge device 31 generates high temperature when electrolyzing gas, the high temperature gas will make the gas humidity become high after passing through the water tank 32, if the gas is electrolyzed again after being discharged, the electrode of the discharge device 31 will generate electric arc easily, thus influencing the service life and operation reliability of the sterilized water preparation device 30, so the sterilizing system 100 of the embodiment of the application can reduce the generation condition of electric arc of the discharge device 31 when electrolyzing gas by condensing and dehumidifying the discharged gas, thus prolonging the service life of the sterilized water preparation device 30 and ensuring the reliable operation of the sterilized water preparation device 30.

In some embodiments, the disinfection system 100 further comprises a controller and a valve assembly 70, the valve assembly 70 being disposed on the gas condensation cycle 50 and the gas condensation regulation branch 60, the controller being in communication with the valve assembly 70 and the humidity detection device 40, the controller being configured to control the valve assembly 70 through the gas humidity detected by the humidity detection device 40 to control the gas to enter the gas condensation cycle 50 and/or the gas condensation regulation branch 60.

The manner in which the valve assembly 70 is provided to control the flow of gas to the gas condensation cycle 50 and/or the gas condensation regulating branch 60 is simple and reliable.

Specifically, the valve assembly 70 includes a first valve body 71 and a second valve body 72, the first valve body 71 being provided on the gas condensation circulation circuit 50, the second valve body 72 being provided on the gas condensation regulation branch 60. The controller can be communicatively coupled to the first valve body 71 and the second valve body 72, respectively. By controlling the opening or closing of the first valve body 71, the circulation of the gas in the gas condensation circulation circuit 50 can be correspondingly turned on or off, and by controlling the opening or closing of the second valve body 72, the circulation of the gas in the gas condensation regulation branch 60 can be correspondingly turned on or off.

More specifically, the first valve body 71 is provided between the gas condensation regulating branch 60 and the gas supply device 20.

Referring to fig. 2 and 3, in some embodiments, the condensing device 10 includes a housing 14 and a semiconductor refrigeration sheet 15, the housing 14 having a receiving cavity, the semiconductor refrigeration sheet 15 being disposed within the receiving cavity to form a condensing channel 11 within the receiving cavity. The gas condensation circuit 50 and the gas condensation regulating branch 60 each comprise a condensation channel 11.

The semiconductor refrigeration sheet 15, also referred to as a thermoelectric refrigeration sheet, is a heat pump.

The semiconductor cooling plate 15 is made using the peltier effect of the semiconductor material. The peltier effect is a phenomenon in which when a direct current passes through a couple composed of two semiconductor materials, a temperature difference is generated between both ends of the couple, and one end absorbs heat and the other end releases heat. The semiconductor refrigeration sheet 15 is controlled by current, and when the current direction is reversed, the cold end and the hot end are also interchanged. In the embodiment of the present application, the left end of the semiconductor refrigeration sheet 15 is taken as a cold end and the right end is taken as a hot end as an example.

The gas condensation circulation loop 50 and the gas condensation regulation branch 60 both include the condensation channel 11, which means that when the gas enters the gas condensation circulation loop 50 and the gas condensation regulation branch 60, the gas can enter the condensation channel 11 to perform condensation dehumidification.

The condensing device 10 can realize high-precision temperature control by adopting the semiconductor refrigerating sheet 15 for refrigerating and condensing, and has very small thermal inertia and quick refrigerating and heating time, so that the condensing reliability is improved. In addition, there is no refrigerant contamination.

Further, the condensation channel 11 includes a first air inlet 12 and a first air outlet 13, and the cross-sectional area of the condensation channel 11 gradually decreases from the first air inlet 12 toward the first air outlet 13.

The cross-sectional area of the condensation channel 11 refers to a cross-sectional area in a direction perpendicular to the extending direction of the condensation channel 11.

Since the cross-sectional area of the condensation channel 11 gradually decreases from the first air inlet 12 to the first air outlet 13, the gas is gradually compressed after entering the condensation channel 11, and the gas can contact the semiconductor refrigeration sheet 15 as much as possible, thereby improving the condensation dehumidification effect.

Specifically, the cross-sectional area of the condensation channel 11 is gradually reduced, and the width, thickness, etc. of the condensation channel 11 may be gradually reduced.

More specifically, the case 14 has a first side wall 141 disposed opposite to the semiconductor refrigeration sheet 15, and a condensation passage 11 is formed between the first side wall 141 and the semiconductor refrigeration sheet 15. The first sidewall 141 is disposed obliquely toward the semiconductor cooling fin 15 from the first air inlet 12 toward the first air outlet 13, or the semiconductor cooling fin 15 is disposed obliquely toward the first sidewall 141.

Through the first side wall 141 and the semiconductor refrigeration piece 15 that incline to set up, can guide gas more paste to the semiconductor refrigeration piece 15 in the flow in-process to promote condensation dehumidification effect. In addition, the inclined arrangement is also simple, so that the overall structure of the condensing device 10 is simple.

In the embodiment of the present application, the accommodating chamber is further formed with a heat dissipation channel 16, and the heat dissipation channel 16 and the condensation channel 11 are respectively located at two opposite sides of the semiconductor refrigeration sheet 15.

By forming the heat dissipation channel 16, heat emitted from the hot end of the semiconductor refrigeration sheet 15 can be evacuated by the air flow in the heat dissipation channel 16, and the heat dissipation efficiency is improved.

Specifically, the semiconductor refrigeration sheet 15 is disposed in the accommodating chamber, and is used for separating the accommodating chamber to form the corresponding heat dissipation channel 16 and condensation channel 11. The semiconductor refrigerating plate 15 not only serves as a condensing member, but also serves as a spacer, so that the manner of forming the heat dissipation channel 16 and the condensing channel 11 in the accommodating cavity is simple, and the overall structure of the condensing device 10 is simplified.

Further, in order to reliably separate the heat radiation passage 16 and the condensation passage 11, a seal 17 is provided between the semiconductor cooling fin 15 and the case 14. The sealing member 17 seals the gap between the semiconductor refrigeration sheet 15 and the case 14, so that the gas cannot flow between the heat dissipation channel 16 and the condensation channel 11 through the gap, and the heat dissipation and condensation process is effective.

In some embodiments, in order to make the heat dissipation of the hot end of the semiconductor refrigeration sheet 15 faster, the condensing device 10 further includes a heat dissipation element 18, where the heat dissipation element 18 is disposed in the heat dissipation channel 16.

Further, the heat sink 18 includes a plurality of heat dissipation fins 181, and the plurality of heat dissipation fins 181 are disposed at intervals. Specifically, the plurality of heat dissipation fins 181 are disposed at intervals from each other along the extending direction of the heat dissipation channel 16.

In other embodiments, the condensing unit 10 may also include a fan in communication with the heat dissipation channel 16.

By providing the blower fan, it is possible to supply a flowing air flow into the heat dissipation passage 16, and further, heat generated from the semiconductor cooling fin 15 is taken away from the heat dissipation passage 16 following the air flow, thereby improving heat dissipation efficiency.

Specifically, the two ends of the heat dissipation channel 16 are respectively provided with an air inlet and an air outlet, the fan can be communicated with the air inlet to blow air into the heat dissipation channel 16, and the fan can also be communicated with the air outlet to suck air into the heat dissipation channel 16, so that flowing air flow can be provided in the heat dissipation channel 16.

In an embodiment of the present application, in order to fully utilize the heat generated by the semiconductor cooling fins 15, when the disinfection system 100 of an embodiment of the present application is used in a dishwasher, the dishwasher includes an inner cavity, through which the heat dissipation channel 16 communicates.

Thus, the heat generated by the semiconductor refrigerating sheet 15 can flow into the inner cavity of the dish washer through the heat dissipation channel 16, and the inner cavity of the dish washer is commonly used for high-temperature cleaning and disinfection of the tableware, so that the heat of the semiconductor refrigerating sheet 15 can enter the inner cavity of the dish washer to assist the dish washer to perform high-temperature cleaning and disinfection of the tableware, and the energy consumption of the high-temperature cleaning and disinfection is reduced.

In particular, in the embodiment of the present application, the housing 14 includes a first housing 142, a second housing 143, and a connection housing 144, where the connection housing 144 is disposed between the first housing 142 and the second housing 143, and the first housing 142, the second housing 143, and the connection housing 144 are spliced with each other to form a receiving cavity.

The first and second cases 142 and 143 are each a cavity structure having one side opened, and the semiconductor refrigeration sheet 15 is installed at the opening of the first case 142 and forms the condensation channel 11 at the side of the semiconductor refrigeration sheet 15 facing the first case 142. The joint between the connection housing 144 and the first housing 142 forms a step, which can limit the semiconductor refrigeration sheet 15, and the sealing member 17 may be disposed between the semiconductor refrigeration sheet 15 and the connection housing 144. The heat sink 18 is disposed on the connection housing 144, and one side of the heat sink 18 is attached to one side of the semiconductor cooling fin 15. The opening of the second housing 143 is covered on a side of the connection housing 144 facing away from the first housing 142 to form the heat dissipation path 16 on a side of the semiconductor cooling fin 15 facing toward the second housing 143.

Referring to fig. 1, in some embodiments, the condensing device 10 further includes a drain 19, the drain 19 being in communication with the sanitizing water preparation device 30. Specifically, the drain opening 19 can communicate with the water tank 32.

Because the water outlet 19 is communicated with the sterilizing water preparation device 30, the condensed water formed after condensation and dehumidification by the condensation device 10 can be recycled, and the water outlet is not required to be additionally communicated with a water outlet pipeline to be discharged to the outside of the equipment, so that the integral structure is simplified.

Further, the disinfection system 100 further comprises a U-tube 80, the U-tube 80 being connected in series between the drain opening 19 and the disinfection water preparation device 30.

By arranging the U-shaped pipe 80, water can be always arranged on a communicating pipe between the water outlet 19 and the sterilizing water preparation device 30, and the water can play a certain role in blocking, so that gas flowing through the inside of the condensing device 10 can be prevented from entering the sterilizing water preparation device 30 through the water outlet 19, and the use of the sterilizing water preparation device 30 is affected.

Specifically, the height of the U-shaped pipe 80 may be determined according to the output pressure of the air supply device 20 and the position height of the condensing device 10, and in summary, the water pressure to satisfy the height of the U-shaped pipe 80 is equal to or greater than the output pressure of the air supply device 20.

In some embodiments, the air supply device 20 is further connected to an external air inlet branch 90, and a check valve 95 is disposed on the external air inlet branch 90, where the check valve 95 is unidirectional from the outside to the air supply device 20.

That is, the air supply device 20 can introduce air to the outside through the external air inlet branch 90 to satisfy the air supply amount of the sterilizing water production device 30.

It should be noted that the gas supply 20 includes a gas source that also needs to continuously deliver gas when the check valve 95 on the inlet branch 90 is closed, so that the gas supply 20 is continuously operated, not just by the inlet of the external inlet branch 90.

Referring to fig. 4, based on the same inventive concept, the present application also provides a sterilization condensation control method applied to the sterilization system 100 in any of the above embodiments, the method comprising:

s100: in response to the sterilization command, controlling the operation of the on-gas condensing circulation loop 50, the off-gas condensing regulation branch 60, and the gas supply device 20;

the disinfection instruction can be a remote controller, an intelligent terminal or a key on the disinfection equipment, and the user generates the disinfection instruction after performing key input operation so as to realize that the disinfection equipment enters self-cleaning. In other embodiments, the disinfection device may also automatically generate disinfection instructions based on environmental parameters or its own status parameters. In an embodiment of the application, the disinfection apparatus is a dishwasher.

When the sterilization apparatus responds to a sterilization command, the operation of the on-gas condensing circulation loop 50, the off-gas condensing regulation branch 60, and the gas supply device 20 can be controlled. The on-gas condensation cycle 50 means that gas can flow through the gas condensation cycle 50, and the off-gas condensation regulation branch 60 means that gas cannot flow through the gas condensation regulation branch 60. The gas supply device 20 is operated by, for example, turning on the gas pump to introduce gas into the sterilizing water production device 30.

S200: judging whether the gas humidity value detected by the humidity detection device 40 is smaller than a preset gas humidity threshold value;

the preset gas humidity threshold may be preset. Determining whether the gas humidity detected by the humidity detection means 40 is less than a preset gas humidity threshold may be performed by the controller. Specifically, after the humidity detection device 40 is communicatively connected to the controller, the controller may obtain the gas humidity value detected by the humidity detection device 40, and then compare the gas humidity value detected by the humidity detection device 40 with a preset gas humidity threshold stored in advance, and determine whether the gas humidity detected by the humidity detection device 40 is less than the preset gas humidity threshold.

S300: if the gas humidity value detected by the humidity detection device 40 is smaller than the preset gas humidity threshold value, controlling the operation of the sterilizing water preparation device 30, and controlling the operation of the condensing device 10 after a preset time period;

when the gas humidity value detected by the humidity detection device 40 is less than the preset gas humidity threshold, the humidity of the gas is indicated to be small, and the operation of the sterilizing water preparation device 30 is controlled at this time, so that the gas with low humidity can enter the sterilizing water preparation device 30 and cannot influence the use of the sterilizing water preparation device 30. In addition, after the preset time, the condensing device 10 is controlled to operate, so that the gas exhausted from the sterilizing water preparing device 30 can be condensed and dehumidified. The preset duration may be preset. The condensation device 10 is controlled to operate after the preset time period is set, because the condensation device 10 directly condenses and dehumidifies the non-redundant gas generated by the disinfection water preparing device 30 if the condensation device 10 is operated at the initial stage because the disinfection water preparing device 30 does not generate redundant gas, such as redundant ozone substances, at the initial stage of the operation of the disinfection water preparing device 30, which affects the successful preparation of the disinfection water, and therefore, the condensation device 10 is controlled to operate after the preset time period, so that the reliability of the disinfection water preparing device 30 for preparing the disinfection water can be improved.

Specifically, when the gas humidity value detected by the humidity detection device 40 is smaller than the preset gas humidity threshold value, timing is started, the preset time period is known, and the condensation device 10 is controlled to operate.

S400: if the gas humidity value detected by the humidity detecting device 40 is not less than the preset gas humidity threshold, the condensing device 10 is controlled to operate until the gas humidity value detected by the humidity detecting device is less than the preset gas humidity threshold.

When the gas humidity value detected by the humidity detection device 40 is not less than the preset gas humidity threshold, the humidity of the gas is indicated to be high, and if the operation of the sterilizing water preparation device 30 is controlled, the gas with high humidity enters the sterilizing water preparation device 30 and affects the use of the sterilizing water preparation device 30. Therefore, the operation of the condensing device 10 is directly controlled, and the sterilizing water can be prepared by using the sterilizing water preparing device 30 after the condensing and dehumidifying treatment is performed on the gas.

The term "until the humidity value of the gas detected by the humidity detection device is less than the preset gas humidity threshold" refers to that, after the gas is condensed and dehumidified by the condensing device 10, the humidity detection device 30 can perform humidity detection on the gas exhausted by the condensing device 10 again, and when it is determined that the humidity value of the gas detected by the humidity detection device is less than the preset gas humidity threshold, the aforementioned step S300 may be performed. When it is determined that the gas humidity value detected by the humidity detection device is still not smaller than the preset gas humidity threshold value, the gas is controlled to continue to be condensed and dehumidified by the condensing device 10.

Therefore, the disinfection condensation control method of the embodiment of the application can ensure that the gas enters the disinfection water preparation device 30 for disinfection water preparation under the condition of low humidity by judging whether the gas humidity value detected by the humidity detection device 40 is smaller than the preset gas humidity threshold value, and enters the disinfection water preparation device 30 for disinfection water preparation after entering the condensation device 10 for dehumidification under the condition of high humidity, thereby protecting the disinfection water preparation device 30, prolonging the service life of the disinfection water preparation device 30 and ensuring the disinfection water preparation device 30 to reliably operate.

Referring to fig. 5, further, after step S300, the method further includes:

s320: re-judging whether the gas humidity detected by the humidity detection means 40 is less than a preset gas humidity threshold;

when it is determined that the gas humidity value detected by the humidity detection device 40 is smaller than the preset gas humidity threshold, and after the operation of the sterilizing water preparation device 30 is controlled and the operation of the condensation device 10 is controlled after the preset time period, the gas is condensed and dehumidified by the condensation device 10 and then discharged, at this time, the humidity of the gas is detected by the humidity detection device 40, so as to obtain the gas humidity value detected by the humidity detection device 40, and further determine whether the gas humidity value is smaller than the preset gas humidity threshold, so as to ensure that the gas humidity entering the sterilizing water preparation device 30 is smaller than the preset gas humidity threshold.

S340: if the gas humidity value detected by the humidity detecting device 40 is not less than the preset gas humidity threshold, the gas condensation regulating branch 60 is controlled to be turned on and the gas condensation circulating loop 50 is controlled to be turned off until the gas humidity value detected by the humidity detecting device 40 is less than the preset gas humidity threshold, and the gas condensation circulating loop 50 is controlled to be turned on and the gas condensation regulating branch 60 is controlled to be turned off.

When the gas humidity value detected by the humidity detecting device 40 is not less than the preset gas humidity threshold, the humidity of the gas is higher, and at this time, the sterilizing water preparing device 30 is already operated, so that the high-humidity gas cannot flow in the gas condensation regulating branch 60, and therefore, the gas condensation regulating branch 60 is conducted, and the high-humidity gas can be returned to the condensing device 10 to be condensed and dehumidified again until the gas humidity value detected by the humidity detecting device 40 is less than the preset gas humidity threshold.

The control of turning on the gas condensation circulation loop 50 and turning off the gas condensation regulation branch 60 until the gas humidity value detected by the humidity detection device is less than the preset gas humidity threshold value means that after the gas passes through the gas condensation regulation branch 60 and is condensed and dehumidified by the condensation device 10, the humidity detection device 30 can again detect the humidity of the gas discharged by the condensation device 10, and when the gas humidity value detected by the humidity detection device is determined to be less than the preset gas humidity threshold value, the gas condensation circulation loop 50 is turned on, so that the gas with low humidity enters the gas condensation circulation loop 50, and thus enters the sterilizing water preparation device 30 for preparing the sterilizing water.

Therefore, when the gas humidity value detected by the humidity detection device 40 is not less than the preset gas humidity threshold value, the gas condensation regulation branch 60 is conducted, so that the high-humidity gas is returned to the condensation device 10 again for condensation and dehumidification, the humidity of the gas can be further reduced, and the gas condensation circulation loop 50 is conducted until the gas humidity value detected by the humidity detection device is less than the preset gas humidity threshold value, so that the low-humidity gas enters the disinfectant preparing device 30, the disinfectant preparing device 30 is further protected, the service life of the disinfectant preparing device 30 is prolonged, and the disinfectant preparing device 30 can reliably operate.

In some embodiments, S340 includes:

if the gas humidity value detected by the humidity detection device 40 is not less than the preset gas humidity threshold, the gas condensation regulation branch 60 is controlled to be turned on, the gas condensation circulation loop 50 is stopped, and the voltage of the sterilizing water preparation device 30 is controlled to be reduced until the gas humidity value detected by the humidity detection device 40 is less than the preset gas humidity threshold, and the gas condensation regulation branch 60 is controlled to be turned on, and the voltage of the sterilizing water preparation device 30 is controlled to be increased.

When the gas humidity value detected by the humidity detection device 40 is not less than the preset gas humidity threshold value, the voltage of the sterilizing water preparation device 30 is controlled to be reduced, so that the sterilizing water preparation device 30 can be prevented from being damaged when the air flow humidity is high, and the service life of the sterilizing water preparation device 30 is further prolonged.

Specifically, if the gas humidity value detected by the humidity detection device 40 is not less than the preset gas humidity threshold, the voltage of the disinfectant preparing device 30 may be controlled to be reduced to a preset first voltage value, and if the gas humidity value detected by the humidity detection device 40 is less than the preset gas humidity threshold, the voltage of the disinfectant preparing device 30 is controlled to be increased to a preset second voltage value, where the preset first voltage value is less than the preset second voltage value.

The preset second voltage value may be a normal voltage value when the sterilizing water preparation device 30 is operated.

Referring to fig. 6, in some embodiments, the sterilization condensation control method further comprises:

s360: if the gas humidity value detected by the humidity detection device 40 is less than the preset gas humidity threshold value, the sterilizing water preparation device 30 is controlled to continuously operate.

When the gas humidity value detected by the humidity detecting device 40 is smaller than the preset gas humidity threshold, the humidity of the gas is smaller, and the operation of the sterilizing water preparing device 30 is maintained, so that the gas with low humidity can enter the sterilizing water preparing device 30 again, and the use of the sterilizing water preparing device 30 is not affected.

4. then the humidity detection device 40 monitors the air flow humidity in real time, and if the air flow humidity S is greater than S0, the discharge device 31 regulates down the voltage; and the line to the discharge means 31 will be cut off, the line to the condensation means 10 is opened, the air flow through the condensation means 10 again flows into the condensation means 10, until the air flow humidity S is less than S0, the line to the discharge means 31 will be opened, the discharge means 31 will resume the normal voltage, and the line to the condensation means 10 is disconnected.
