[0026] Dishwashers are popular with users because of their dishwashing and drying functions. The dishwashing function of dishwashers is mainly achieved through drying technology, which currently includes internal circulation drying, external circulation hot air drying, and automatic door opening drying, among others. External circulation hot air drying and automatic door opening drying both require the high-temperature, high-humidity air inside the dishwasher to come into contact with the outside air. When this high-temperature, high-humidity air comes into contact with the outside air, condensation will form on the dishwasher. The presence of this condensation poses a safety threat to users during daily use. Therefore, how to eliminate the condensation that forms after drying in dishwashers is a problem that urgently needs to be solved.

[0027] The present application will now be described in detail with reference to specific embodiments.

[0028] In the following method embodiments, for ease of explanation, only the dishwasher is described as the subject performing each step.

[0029] Please see Figure 1 This is a schematic flowchart illustrating a drying control method for a washing machine according to an embodiment of this application. Figure 1As shown, the method described in this application embodiment may include the following steps:

[0030] S101, determine the initial gas mixing ratio of the external intake gas and the internal exhaust gas of the washing appliance.

[0031] Washing appliances can refer to electrical appliances such as dishwashers that can store tableware and have a tableware drying function. Washing appliances have a washing chamber and an exhaust system. The washing chamber refers to the cavity used for washing or storing tableware, and the exhaust system refers to a device with an exhaust function. The exhaust system includes a first air inlet, a second air inlet, and an exhaust outlet. The first air inlet is connected to the washing chamber, and the second air inlet and the exhaust outlet are respectively connected to the outside of the washing chamber. The gas discharged by the exhaust system includes at least one of the following: gas discharged from the washing chamber and gas drawn in from the outside of the washing chamber.

[0032] For details, please refer to Figure 2 A schematic diagram of an exhaust system is shown. Figure 2 As shown, Figure 2 The arrows shown represent the flow directions of various gases. The externally drawn-in gas and the internally discharged gas mix in the exhaust device 100. The washing appliance can control the volume of the externally drawn-in gas and the internally discharged gas entering the exhaust device by using a fan installed in the air duct where the internally discharged gas is located and a fan installed in the air duct where the externally drawn-in gas is located. The washing appliance can also control the volume of the externally drawn-in gas and the internally discharged gas entering the exhaust device by using a rotatable proportional valve installed between the first air inlet and the second air inlet.

[0033] The initial gas mixing ratio can be understood as the gas mixing ratio of the externally drawn-in gas and the internally discharged gas in the exhaust device before exhaust begins. Specifically, the gas mixing ratio of the externally drawn-in gas and the internally discharged gas can be understood as the ratio of the volume of the externally drawn-in gas to the volume of the internally discharged gas.

[0034] In some embodiments, the initial gas mixing ratio can be determined by the rinsing temperature corresponding to the current washing mode of the washing appliance. Therefore, the rinsing temperature corresponding to the current washing mode of the washing appliance can be determined first, and then the initial gas mixing ratio of the external intake gas and the internal exhaust gas can be determined according to the rinsing temperature.

[0035] In some other embodiments, the initial gas mixing ratio can be determined by a pre-configured preset gas mixing ratio threshold, in which case the preset gas mixing ratio threshold can be used as the initial gas mixing ratio of externally inhaled gas and internally discharged gas.

[0036] S102, obtain the ambient temperature outside the washing chamber, and obtain the dew point temperature of the mixed gas corresponding to the gas drawn in from the outside and the gas discharged from the chamber.

[0037] Ambient temperature refers to the actual ambient temperature of the environment in which the washing appliance is located.

[0038] The dew point temperature of a gas mixture can be understood as the temperature at which a saturated gas mixture begins to condense and form dew. The gas mixture includes at least one of the external intake gas and the gas discharged from the cavity.

[0039] In some embodiments, the step of obtaining the ambient temperature outside the washing chamber can be: obtaining the external ambient temperature measured by a temperature sensor before running the current washing mode; or receiving the external ambient temperature sent by a server, wherein the external ambient temperature can be sent to the server by an electrical device located in the same area as the washing appliance.

[0040] The step of obtaining the dew point temperature of the mixed gas corresponding to the externally inhaled gas and the internally discharged gas can specifically be as follows: Obtain the gas temperature and relative humidity of the externally inhaled gas and the internally discharged gas, and calculate the mixed gas dew point temperature using the dew point temperature calculation formula. The gas temperature can be measured by a temperature sensor installed in the exhaust device, and the gas relative humidity can be measured by a humidity sensor installed in the exhaust device.

[0041] The formula for calculating dew point temperature satisfies the following formula:

[0042]

[0043] Where m takes the value 17.62, and m is a fixed value; T n The value is 243.12℃, T n t represents a fixed value; t represents temperature, which is a variable value; RH represents relative humidity, which is a variable value; t d (t,RH) represents the dew point temperature. When t is the gas temperature and RH is the relative humidity of the gas, the calculated t... d (t,RH) represents the dew point temperature of the mixed gas corresponding to the gas inhaled from the outside and the gas exhaled from the cavity.

[0044] S103 performs gas mixing regulation on the inhaled gas and the exhaust gas based on the ambient temperature, the dew point temperature of the mixed gas, the initial gas mixing ratio, and the reference gas mixing ratio threshold.

[0045] The reference gas mixing ratio threshold can be understood as a ratio threshold used to determine whether to perform gas mixing regulation treatment on the external inhaled gas and the gas discharged from the cavity.

[0046] In some embodiments, the ambient temperature and the dew point temperature of the mixed gas can be monitored, and the initial gas mixing ratio and the reference gas mixing ratio threshold can be detected. Based on the temperature monitoring results of the ambient temperature and the dew point temperature of the mixed gas and the gas mixing ratio monitoring results, the gas inhaled from the outside and the gas discharged from the cavity can be regulated by gas mixing.

[0047] Specifically, when the dew point temperature of the mixed gas is detected to be higher than the ambient temperature, the gas mixing ratio of the gas inhaled from the outside and the gas discharged from the cavity can be adjusted regardless of the gas mixing ratio monitoring result; when the dew point temperature of the mixed gas is detected to be lower than the ambient temperature and the initial gas mixing ratio is higher than the reference gas mixing ratio threshold, the gas mixing ratio of the gas inhaled from the outside and the gas discharged from the cavity can be adjusted; when the dew point temperature of the mixed gas is detected to be lower than the ambient temperature and the initial gas mixing ratio is less than or equal to the reference gas mixing ratio threshold, the adjustment of the gas mixing ratio of the gas inhaled from the outside and the gas discharged from the cavity can be stopped. After each adjustment of the gas mixing ratio of the externally inhaled gas and the internally discharged gas, the step of obtaining the dew point temperature of the mixed gas in step S102 is repeated. Then, the dew point temperature of the mixed gas and the current gas mixing ratio of the externally inhaled gas and the internally discharged gas are monitored again to determine whether the gas mixing ratio needs to be adjusted again. The adjustment of the gas mixing ratio is stopped only when the dew point temperature of the mixed gas is lower than the ambient temperature and the current gas mixing ratio of the externally inhaled gas and the internally discharged gas is less than or equal to the reference gas mixing ratio threshold.

[0048] When the detected dew point temperature of the mixed gas is higher than the ambient temperature, regardless of the monitoring result of the gas mixing ratio, the gas mixing ratio of the externally inhaled gas and the gas discharged from the cavity can be left unchanged. After a certain delay, the step of obtaining the dew point temperature of the mixed gas of the externally inhaled gas and the gas discharged from the cavity is executed again. Then, the gas mixing ratio of the mixed gas dew point temperature and the externally inhaled gas and the gas discharged from the cavity is monitored again to determine whether the gas mixing ratio needs to be adjusted again. Only when the detected dew point temperature of the mixed gas is lower than the ambient temperature and the gas mixing ratio is less than or equal to the reference gas mixing ratio threshold, the adjustment of the gas mixing ratio of the externally inhaled gas and the gas discharged from the cavity is stopped.

[0049] In this embodiment, the washing appliance has a washing chamber and an exhaust device. The exhaust device includes a first air inlet, a second air inlet, and an exhaust outlet. The first air inlet is connected to the washing chamber, and the second air inlet and the exhaust outlet are respectively connected to the outside of the washing chamber. The gas discharged by the exhaust device includes at least one of the following: exhaust gas discharged from the washing chamber and gas drawn in from the outside of the washing chamber. First, the initial gas mixing ratio of the gas drawn in from the outside and the gas discharged from the chamber is determined. Then, the ambient temperature outside the washing chamber and the dew point temperature of the mixed gas corresponding to the gas drawn in from the outside and the gas discharged from the chamber are obtained. Then, based on the ambient temperature, the dew point temperature of the mixed gas, the initial gas mixing ratio, and a reference gas mixing ratio threshold, the gas mixing of the gas drawn in from the outside and the gas discharged from the chamber is adjusted. By adopting the above technical solution, by monitoring the gas mixing ratio and dew point temperature of the exhaust gas composed of the gas drawn in from the outside and the gas discharged from the chamber, and adjusting the gas mixing ratio, the gas discharge gas of the exhaust device can be adjusted in a timely manner, thereby avoiding the generation of condensate on the washing appliance when the exhaust gas is discharged and comes into contact with the external environment.

[0050] Please see Figure 3 This is a schematic flowchart illustrating a drying control method for a washing machine according to an embodiment of this application. Figure 3 As shown, the method described in this application embodiment may include the following steps:

[0051] S301, determine the rinsing temperature corresponding to the current washing mode of the washing appliance, and determine the initial gas mixing ratio of the external intake gas and the internal exhaust gas based on the rinsing temperature.

[0052] The current washing mode refers to the washing mode that the washing appliance is currently operating in. Washing modes can include heavy-duty wash, gentle wash, quick wash, mixed wash, etc., and the current washing mode can be any of these modes. Different washing modes may also use different rinsing temperatures.

[0053] In some embodiments, the step of determining the rinsing temperature corresponding to the current washing mode of the washing appliance may involve: first determining the current washing mode currently being operated by the washing appliance, and then obtaining the rinsing temperature corresponding to the current washing mode. Since the rinsing temperature for each washing mode is preset, the rinsing temperature corresponding to that washing mode can be directly obtained after determining the washing mode. It should be noted that the rinsing temperature in this embodiment specifically refers to the rinsing temperature of the last rinsing operation in the washing mode.

[0054] The step of determining the initial gas mixing ratio of externally inhaled gas and internally discharged gas based on the rinsing temperature can be specifically: obtaining the gas mixing ratio mapping relationship, and querying the initial gas mixing ratio of externally inhaled gas and internally discharged gas corresponding to the rinsing temperature in the gas mixing ratio mapping relationship.

[0055] The gas mixing ratio mapping relationship can be understood as a correspondence between at least one reference rinsing temperature and the corresponding gas mixing ratio. Since washing appliances have multiple washing modes, each with a different rinsing temperature, a corresponding gas mixing ratio can be set for each rinsing temperature. A correspondence between the set reference gas mixing ratio and its corresponding reference rinsing temperature is established and pre-stored in the gas mixing ratio mapping relationship. Therefore, when the reference rinsing temperature in the gas mixing ratio mapping relationship is the rinsing temperature, the corresponding reference gas mixing ratio is the initial gas mixing ratio of the gas drawn in from the outside and the gas discharged from the cavity.

[0056] S302, after the washing program in the current washing mode of the washing appliance ends, the gas mixing ratio of the gas drawn in from the outside and the gas discharged from the cavity is controlled to be at a preset gas mixing ratio threshold, and the preset gas mixing ratio threshold is used as the initial gas mixing ratio.

[0057] The preset gas mixing ratio threshold refers to the gas ratio threshold between externally inhaled gas and internally discharged gas, which is preset based on application experience. The initial gas mixing ratio can be: when the discharged gas in the exhaust device only contains externally inhaled gas, the initial gas mixing ratio is a preset ratio, for example, a preset ratio of 1:0; when the discharged gas in the exhaust device contains both externally inhaled gas and internally discharged gas, the initial mixing ratio can be a fixed ratio, wherein the fixed ratio is different from the preset ratio.

[0058] Specifically, the preset gas mixing ratio threshold can be associated with a preset maximum valve angle, which is the maximum valve angle of the air intake control valves corresponding to the second air inlet and the first air inlet. Please refer to [link / reference]. Figure 4 , Figure 4 A schematic diagram of an air intake control valve plate is shown. Figure 4 In this configuration, the air intake control valve is used to adjust the opening size of the first air inlet and the second air inlet. The air intake control valve can be located at any position on the arc from the first position to the second position, or it can be in either the first or the second position. Figure 4When the air intake control valve is positioned close to the second position (i.e., infinitely close to but not actually in the second position), the valve angle is the maximum valve angle in this embodiment (i.e., the preset maximum valve angle). In this state, the ratio of externally drawn-in gas to internally discharged gas is a preset gas mixing ratio threshold. It can be seen that when the initial gas mixing ratio is the preset gas mixing ratio threshold, the opening of the second air inlet is almost at its maximum, while the opening of the first air inlet is a small opening (not zero). At this time, the volume of externally drawn-in gas in the exhaust device is almost at its maximum, and the volume of internally drawn-in gas is slightly greater than zero. Since there is a lot of moisture in the washing chamber at the beginning of drying, the first air inlet is only slightly open to ensure that condensation does not easily occur during the initial drying stage.

[0059] Specifically, step S302 can be performed as follows: after the washing program in the current washing mode of the washing appliance ends, the air intake control valve is adjusted based on the maximum valve angle. The maximum valve angle is used to control the gas mixing ratio of the external intake gas and the internal exhaust gas to be at a preset gas mixing ratio threshold, and the preset gas mixing ratio threshold is used as the initial gas mixing ratio.

[0060] S303, obtain the ambient temperature outside the washing chamber.

[0061] In some embodiments, step S303 may specifically involve: acquiring the external ambient temperature measured by a temperature sensor before running the current washing mode; or receiving the external ambient temperature sent by a server, wherein the external ambient temperature may be sent to the server by an appliance located in the same area as the washing appliance.

[0062] S304, obtain the dew point temperature of the mixed gas corresponding to the gas inhaled from the outside and the gas discharged from the cavity.

[0063] In some embodiments, the gas temperature and relative humidity of the inhaled gas and the exhaust gas are obtained, and the dew point temperature of the mixed gas is calculated using a dew point temperature calculation formula. The gas temperature can be measured by a temperature sensor installed in the exhaust device, and the gas relative humidity can be measured by a humidity sensor installed in the exhaust device.

[0064] The formula for calculating dew point temperature satisfies the following formula:

[0065]

[0066] Where m takes the value 17.62, and m is a fixed value; T n The value is 243.12℃, T nt represents a fixed value; t represents temperature, which is a variable value; RH represents relative humidity, which is a variable value; t d (t,RH) represents the dew point temperature. When t is the gas temperature and RH is the relative humidity of the gas, the calculated t... d (t,RH) represents the dew point temperature of the mixed gas corresponding to the gas inhaled from the outside and the gas exhaled from the cavity.

[0067] S305 adjusts the gas mixing ratio of inhaled gas and exhaust gas based on ambient temperature, gas mixture dew point temperature, initial gas mixing ratio, and reference gas mixing ratio threshold.

[0068] In some embodiments, executing S305 may include: A1, if the dew point temperature of the mixed gas is greater than the ambient temperature, and / or the initial gas mixing ratio is greater than the reference gas mixing ratio threshold, then perform gas mixing ratio adjustment processing on the externally inhaled gas and the internally discharged gas, and execute the step of obtaining the dew point temperature of the mixed gas corresponding to the externally inhaled gas and the internally discharged gas; A2, if the dew point temperature of the mixed gas is less than the ambient temperature, and the initial gas mixing ratio is less than the reference gas mixing ratio threshold, then stop performing gas mixing ratio adjustment processing on the externally inhaled gas and the internally discharged gas.

[0069] Specifically, the exhaust device includes a first speed-regulating fan and a second speed-regulating fan. The first speed-regulating fan is installed in the first air duct corresponding to the first air inlet, and the second speed-regulating fan is installed in the second air duct corresponding to the second air inlet. When executing A1, the gas mixing ratio of the gas drawn in from the outside and the gas discharged from the cavity is adjusted. This can be achieved by controlling the first speed-regulating fan to adjust the first wind speed of the gas discharged from the washing cavity in the first air duct, and controlling the second speed-regulating fan to adjust the second wind speed of the gas drawn in from the outside in the second air duct, so as to adjust the gas mixing ratio of the gas discharged from the cavity and the gas drawn in from the outside.

[0070] The system comprises two fan components: a first variable-speed fan to control the airflow speed of the gas discharged from the cavity, and a second variable-speed fan to control the airflow speed of the gas drawn in from the outside. For example, increasing the speed of the second variable-speed fan increases the volume of gas drawn in from the outside, while decreasing the speed of the first variable-speed fan decreases the volume of gas discharged from the cavity. This alters the gas mixing ratio, effectively regulating it.

[0071] Specifically, the exhaust device includes a valve plate, which is rotatably mounted between the first air inlet and the second air inlet. During execution A2, it adjusts the gas mixing ratio between the externally drawn-in gas and the internally discharged gas. This can be achieved by adjusting the opening of the first and / or second air inlets using the valve plate. When the valve plate rotates to a position where the opening of the first air inlet increases and the opening of the second air inlet decreases, the volume of the discharged gas increases and the volume of the externally drawn-in gas decreases, thereby changing the gas mixing ratio and achieving proportional adjustment. Conversely, when the valve plate rotates to a position where the opening of the first air inlet decreases and the opening of the second air inlet increases, the volume of the discharged gas decreases and the volume of the externally drawn-in gas increases, again achieving the effect of changing the gas mixing ratio and achieving proportional adjustment.

[0072] Specifically, during execution A1, after adjusting the gas mixing ratio of the inhaled gas and the exhaust gas, the process further includes: obtaining a first preset delay duration; and after the first preset delay duration is reached, obtaining the dew point temperature of the mixed gas corresponding to the inhaled gas and the exhaust gas. In other words, after adjusting the gas mixing ratio, the dew point temperature of the mixed gas is obtained again only after the first preset delay duration has elapsed. This involves obtaining the gas temperature and relative humidity of the inhaled gas and the exhaust gas again to calculate the dew point temperature. Furthermore, the magnitude of the dew point temperature relative to the ambient temperature and the magnitude of the adjusted gas mixing ratio relative to a reference gas mixing ratio threshold are monitored again to determine whether further adjustment of the inhaled gas and the exhaust gas is necessary. Thus, after adjusting the gas mixing ratio, by waiting for the first preset delay duration to allow the inhaled gas and the exhaust gas to fully mix and stabilize before obtaining the dew point temperature again, the error in the re-obtained dew point temperature is reduced, ensuring the validity of the dew point temperature reading.

[0073] Optionally, the first preset delay duration can be set to any value between 5 and 60 seconds.

[0074] When executing A1, the specific steps are as follows: a1, if the dew point temperature of the mixed gas is greater than the ambient temperature, the gas mixing ratio of the externally inhaled gas and the gas discharged from the cavity is increased, and the step of obtaining the dew point temperature of the mixed gas corresponding to the externally inhaled gas and the gas discharged from the cavity is executed; a2, if the dew point temperature of the mixed gas is less than the ambient temperature, and the initial gas mixing ratio is greater than the reference gas mixing ratio threshold, the gas mixing ratio of the externally inhaled gas and the gas discharged from the cavity is decreased, and the step of obtaining the dew point temperature of the mixed gas corresponding to the externally inhaled gas and the gas discharged from the cavity is executed.

[0075] When executing a1, the dew point temperature of the mixed gas can be monitored to see if it is higher than the ambient temperature. If it is, the initial gas mixing ratio can be increased directly without comparing it to the reference mixing ratio threshold. This increased mixing ratio can be either the volume ratio of the externally drawn gas to the volume ratio of the gas discharged from the cavity, or the volume ratio of the externally drawn gas to the total gas volume in the exhaust device. Both ratios can be increased by increasing the volume of the externally drawn gas and decreasing the volume of the gas discharged from the cavity. Because the dew point temperature of the mixed gas is higher than the ambient temperature, directly discharging this temperature-sensitive gas through the exhaust device would pose a condensation risk upon contact with the external environment. Therefore, increasing the mixing ratio lowers the dew point temperature of the mixed gas, thus reducing the condensation risk. After increasing the gas mixing ratio of the inhaled gas and the exhaust gas, the step of acquiring the dew point temperature of the mixed gas can be performed after a first preset delay period. This way, after increasing the gas mixing ratio, by waiting for the first preset delay period to allow the inhaled gas and exhaust gas to mix completely and stabilize, the dew point temperature of the mixed gas is acquired again, reducing the error of the re-acquired dew point temperature and ensuring its validity. Alternatively, during execution a1, it can be monitored whether the dew point temperature of the mixed gas is higher than the ambient temperature, and simultaneously whether the gas mixing ratio is less than or equal to a reference mixing ratio threshold.

[0076] When executing a2, the dew point temperature of the mixed gas can be monitored to see if it is higher than the ambient temperature. If the dew point temperature is lower than the ambient temperature, the gas mixing ratio can be monitored to see if it is lower than or equal to a reference mixing ratio threshold. When the dew point temperature is lower than the ambient temperature and the gas mixing ratio is higher than the reference mixing ratio threshold, the gas mixing ratio of the externally drawn gas and the internally discharged gas is reduced. This reduced gas mixing ratio can be either the volume ratio of the externally drawn gas to the internally discharged gas, or the volume ratio of the externally drawn gas to the total gas volume in the exhaust device. Both of these volume ratios can be reduced by decreasing the volume of the externally drawn gas and increasing the volume of the internally discharged gas. Because the gas mixing ratio of the externally drawn gas and the internally discharged gas is higher than the reference mixing ratio threshold at this time, directly discharging these gases through the exhaust device would pose a risk of condensation upon contact with air in the external environment. Therefore, reducing the gas mixing ratio of the externally drawn gas and the internally discharged gas reduces this risk of condensation. After reducing the gas mixing ratio of the inhaled gas and the exhaust gas, the step of acquiring the dew point temperature of the mixed gas can be performed after a first preset delay period. This way, after reducing the gas mixing ratio, by waiting for the first preset delay period to allow the inhaled gas and exhaust gas to mix completely and stabilize, the dew point temperature of the mixed gas is acquired again, reducing the error of the re-acquired dew point temperature and ensuring its validity. Alternatively, when executing a2, it can be monitored whether the dew point temperature of the mixed gas is higher than the ambient temperature, and simultaneously whether the gas mixing ratio is less than or equal to a reference mixing ratio threshold.

[0077] When executing A2, if the dew point temperature of the mixed gas is lower than the ambient temperature and the gas mixing ratio is less than or equal to the reference gas mixing ratio threshold, the gas mixing ratio adjustment for the external intake gas and the internal exhaust gas is no longer performed. This is because the dew point temperature of the mixed gas in this state is lower than the ambient temperature, and the gas mixing ratio is less than or equal to the reference gas mixing ratio threshold. Directly discharging this state of external intake gas and internal exhaust gas through the exhaust device would result in a low probability of condensation when they encounter air in the external environment. Therefore, there is no need to adjust the gas mixing ratio to reduce the risk of condensation, and the process can directly proceed to the next stage of drying. This involves using hot air drying, high-temperature heating, or other drying technologies to dry the dishes inside the washing equipment, replenishing the evaporation energy during the drying process and thus accelerating the drying rate.

[0078] It should be noted that step S305 can be performed after the washing program of the current washing mode is running and before the hot air drying program is running.

[0079] S306 performs time delay processing on the inhaled gas and the exhaust gas from the cavity based on the ambient temperature, the dew point temperature of the mixed gas, the initial gas mixing ratio, and the reference gas mixing ratio threshold.

[0080] Specifically, if the dew point temperature of the mixed gas is higher than the ambient temperature, a second preset delay time is obtained. After the second preset delay time is reached, the step of obtaining the dew point temperature of the mixed gas corresponding to the external intake gas and the internal exhaust gas is executed. Because the dew point temperature of the mixed gas corresponding to the external intake gas and the internal exhaust gas is higher than the ambient temperature at this time, directly discharging the external intake gas and the internal exhaust gas through the exhaust device would pose a risk of condensation when they encounter the air in the external environment. Therefore, the second preset delay time is waited for, and the dew point temperature of the mixed gas of the external intake gas and the internal exhaust gas is obtained again. That is, the gas temperature and relative humidity of the external intake gas and the internal exhaust gas are collected again to calculate the dew point temperature of the mixed gas. The magnitude of the dew point temperature of the mixed gas and the ambient temperature are monitored again, and the magnitude of the gas mixing ratio and the reference mixed gas ratio threshold are monitored to determine whether the external intake gas and the internal exhaust gas need to be adjusted again to reduce the risk of condensation of the external intake gas and the internal exhaust gas after gas adjustment.

[0081] Optionally, the second preset delay duration can be set to any value between 1 and 120 seconds.

[0082] It should be noted that step S306 can be performed after the washing program of the current washing mode is running and before the hot air drying program is running.

[0083] In this embodiment, firstly, the rinsing temperature corresponding to the current washing mode of the washing appliance is determined. Based on the rinsing temperature, the initial gas mixing ratio of the externally drawn-in gas and the internally discharged gas is determined. Alternatively, after the washing program in the current washing mode of the washing appliance ends, the gas mixing ratio of the externally drawn-in gas and the internally discharged gas is controlled to be at a preset gas mixing ratio threshold, and the preset gas mixing ratio threshold is used as the initial gas mixing ratio. Then, the ambient temperature outside the washing cavity is obtained, and the dew point temperature of the mixed gas corresponding to the externally drawn-in gas and the internally discharged gas is obtained. Based on the ambient temperature, the mixed gas dew point temperature, the initial gas mixing ratio, and the reference gas mixing ratio threshold, the gas mixing ratio of the externally drawn-in gas and the internally discharged gas is adjusted. Based on the ambient temperature, the mixed gas dew point temperature, the initial gas mixing ratio, and the reference gas mixing ratio threshold, the externally drawn-in gas and the internally discharged gas are subjected to a delay process. This application embodiment monitors the dew point temperature of the mixture of externally inhaled gas and internally discharged gas based on the ambient temperature. This facilitates the adjustment or delay of the gas ratio of the externally inhaled gas and internally discharged gas based on the monitoring results of the mixed gas dew point temperature and the gas mixing ratio, thereby reducing the risk of condensation when the exhaust device discharges externally inhaled gas and internally discharged gas.
