[0040] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 , an embodiment of the ventilation method for a washing appliance in an embodiment of the present invention includes:

[0041] The ventilation system of the washing appliance comprises: a sterilizing inner tank, an internal and external circulation switching mechanism and a condensing circulation channel; the air inlet and the exhaust port of the sterilizing inner tank are respectively connected to the two ends of the condensing circulation channel, and the internal and external circulation switching mechanism is used to switch the circulation state of the condensing circulation channel;

[0042] In one embodiment, the internal and external circulation switching mechanism includes an outer shell, an inner shell and a semicircular gate piece, the outer shell and the inner shell are spliced ​​and fixed front and back and a condensation chamber is formed between the two, one end of the condensation chamber is connected to the dry air intake component, and the other end of the condensation chamber is connected to the condensation exhaust component, a semicircular window is opened on the outer shell, the gate piece is arranged concentrically with the semicircular window, and the center of the gate piece is rotatably matched with the outer shell, the two radial sides of the gate piece are respectively formed with a rearward protruding blocking edge, and a baffle is formed at the center of the gate piece, and the baffle is moved along the The center line of the gate plate extends in a direction away from the gate plate, the baffle has a preset width along the front-to-back direction, and the inner shell is provided with a switching motor that is transmission-connected to the center of the gate plate, and the switching motor is used to drive the gate plate to rotate 180° each time, and: when the gate plate covers the semicircular window, the baffle edge is aligned with the bottom of the condensation chamber; when the gate plate is away from the semicircular window, the baffle coincides with the center line of the semicircular window, and the condensation chamber is divided into two left and right unit chambers by the baffle, and the baffle edge is aligned with the bottom of the condensation chamber.

[0043] In one embodiment, the condensation circulation channel includes a dry air inlet assembly and a condensation exhaust assembly, wherein the dry air inlet assembly is connected to the air inlet of the sterilization liner, and the condensation exhaust assembly is connected to the exhaust port of the sterilization liner.

[0044] It should be noted that the drying air intake assembly and the condensing exhaust assembly are both drying assemblies and condensing assemblies of existing dishwashers, and their specific structures and working principles are all existing technologies, which will not be described in detail here.

[0045] The washing appliance ventilation method comprises the steps of:

[0046] 101. Obtain the working state of the sterilization liner. If the working state is the standby state, switch the condensation circulation channel to the internal circulation mode through the internal and external circulation switching mechanism, so that the gas in the sterilization liner circulates along the direction of the condensation circulation channel;

[0047] 102. Obtaining an internal humidity value of the sterilization liner when it is in an internal circulation mode and an environmental humidity value outside the sterilization liner, and comparing the internal humidity value and the environmental humidity value with a preset humidity condition;

[0048] In this embodiment, the internal circulation mode is used to ensure that the gas in the sterilization liner can circulate, which helps to evenly distribute the temperature and humidity in the sterilization liner, effectively improve the accuracy of obtaining the internal humidity value, and use the preset humidity conditions to monitor the humidity status during the sterilization process in real time to ensure that the sterilization environment meets the requirements, thereby ensuring the sterilization effect.

[0049] 103. If the internal humidity value and the ambient humidity value meet the preset humidity conditions, the condensation circulation channel is switched to the external circulation mode through the internal and external circulation switching mechanism;

[0050] In this embodiment, when the internal humidity value and the ambient humidity value meet the preset conditions (i.e., the humidity inside the sterilization liner and the environment is in a dry and comfortable state), the sterilization liner is switched to the external circulation mode, which not only helps to discharge excess water vapor in the liner to prevent oversaturation, but also introduces fresh air at the same time to maintain a suitable working environment for the sterilization liner.

[0051] 104. If the internal humidity value and the ambient humidity value do not meet the preset humidity conditions, the internal and external circulation switching mechanism is used to keep the condensation circulation channel in the internal circulation mode, and the gas in the sterilization liner is separated from the water vapor through the condensation circulation channel until the internal humidity value and the ambient humidity value meet the preset humidity conditions, and then the condensation circulation channel is switched to the external circulation mode through the internal and external circulation switching mechanism.

[0052] In this embodiment, when the internal humidity value and the ambient humidity value do not meet the preset conditions (i.e., the sterilization inner container is in a humid state), the internal circulation mode is maintained, and the gas is separated from the water vapor through the condensation circulation channel until the humidity condition is met. This can effectively control the humidity in the sterilization inner container, avoid affecting the sterilization effect due to improper humidity, and avoid unnecessary energy waste.

[0053] In the embodiment of the present invention, the internal circulation mode can ensure that the gas in the sterilization liner can circulate, which helps to evenly distribute the temperature and humidity in the sterilization liner, effectively improve the accuracy of obtaining the internal humidity value, and use the preset humidity conditions to monitor the humidity state in the sterilization process in real time to ensure that the sterilization environment meets the requirements, thereby ensuring the sterilization effect; when the humidity in the sterilization liner and the environment is in a dry and comfortable state, the sterilization liner is switched to the external circulation mode, which not only helps to discharge the excess water vapor in the liner to prevent oversaturation, but also can introduce fresh air at the same time to maintain a suitable working environment for the sterilization liner; when the sterilization liner is in a humid state, the internal circulation mode is maintained, and the gas is separated from the water vapor through the condensation circulation channel until the humidity conditions are met. This can effectively control the humidity in the sterilization liner, avoid affecting the sterilization effect due to improper humidity, and avoid unnecessary energy waste.

[0054] See also Figure 2 The second embodiment of the ventilation method for a washing appliance in the embodiment of the present invention includes:

[0055] The washing appliance ventilation system further comprises a door ventilation mechanism, which is arranged on the door of the sterilization inner tank and is in communication with the sterilization inner tank;

[0056] In one embodiment, the door body ventilation mechanism includes a door body air duct device arranged on the door body of the sterilization inner tank, the air duct device includes a front shell and a rear shell that are spliced ​​and fixed together front and back, an exhaust duct, an air inlet duct and a common channel are formed in a cavity between the front shell and the rear shell, an air inlet fan is provided in the air inlet duct, and an exhaust fan is provided in the exhaust duct, an air inlet port at the lower end of the air inlet duct and an exhaust port at the lower end of the exhaust duct are both connected to the outside of the door body, an upper end of the exhaust duct and an upper end of the air inlet duct are both connected to the common channel, and the common air port at the upper end of the common channel is connected to the inner side of the door body, and a baffle that can be flipped left and right and a baffle driving mechanism are provided at the junction of the upper end of the exhaust duct and the upper end of the air inlet duct, and the baffle driving mechanism is used to drive the baffle to flip left and right, so as to selectively connect the exhaust duct and the air inlet duct to the common channel.

[0057] If the internal humidity value and the ambient humidity value meet the preset humidity condition, the condensation circulation channel is switched to the external circulation mode through the internal and external circulation switching mechanism, and further includes:

[0058] 201. If the internal humidity value and the ambient humidity value meet the preset humidity conditions, the door ventilation mechanism is switched to the air intake mode.

[0059] In this embodiment, the ventilation function of the door ventilation mechanism can be used to discharge moisture and odor generated in the sterilization cavity, and fresh air can be introduced at the same time, which helps to improve the sterilization efficiency in the sterilization tank. The air intake mode of the door ventilation mechanism is combined with the external circulation mode to reduce dependence on the condensation circulation channel, thereby reducing energy consumption and effectively improving the air quality of the sterilization cavity.

[0060] See also Figure 3 The third embodiment of the ventilation method for a washing appliance in the embodiment of the present invention includes:

[0061] If the internal humidity value and the ambient humidity value do not meet the preset humidity condition, the condensation circulation channel is kept in the internal circulation mode through the internal and external circulation switching mechanism, and the gas in the sterilization liner is separated from the water vapor through the condensation circulation channel until the internal humidity value and the ambient humidity value meet the preset humidity condition, and the condensation circulation channel is switched to the external circulation mode through the internal and external circulation switching mechanism, and further includes:

[0062] 301. If the internal humidity value and the ambient humidity value do not meet the preset humidity conditions, the door ventilation mechanism is switched to the exhaust mode.

[0063] In this embodiment, the internal humidity value and the ambient humidity value are monitored in real time through the preset humidity conditions. If the sterilization liner has a problem of too high humidity, the condensable circulation channel can condense and dry the air in the sterilization liner to achieve the dehumidification effect, which can effectively prevent the corrosion or mildew caused by excessive humidity inside the sterilization liner. In addition, when the humidity in the sterilization liner is restored to a dry and comfortable level, the exhaust mode of the door ventilation mechanism is combined with the external circulation mode to improve the exhaust efficiency of water vapor, ensure the air quality inside the sterilization liner, avoid affecting the sterilization liner environment due to excessive humidity, and keep the sterilization liner dry and comfortable.

[0064] See also Figure 4 The fourth embodiment of the ventilation method for a washing appliance in the embodiment of the present invention includes:

[0065] If the internal humidity value and the ambient humidity value meet the preset humidity condition, the condensation circulation channel is switched to the external circulation mode through the internal and external circulation switching mechanism, including:

[0066] The humidity conditions include an internal reference humidity value and an environmental reference humidity value;

[0067] 401. When the internal humidity value is less than or equal to the internal reference humidity value, the ambient humidity value is compared with the ambient reference humidity value;

[0068] 402. If the ambient humidity value is less than or equal to the ambient reference humidity value, the condensation circulation channel is switched to the external circulation mode through the internal and external circulation switching mechanism, and the door ventilation mechanism is switched to the air intake mode.

[0069] In this embodiment, when the internal humidity value is less than or equal to the internal reference humidity value and the ambient humidity value is less than or equal to the ambient reference humidity value, this condition indicates that the internal humidity value and the ambient humidity value are both at normal levels (i.e., the air in the sterilization liner and the air in the environment are both in a dry and comfortable state), the sterilization liner is switched to the external circulation mode, which not only helps to discharge excess water vapor in the liner to prevent oversaturation, but also introduces fresh air at the same time to maintain a suitable working environment for the sterilization liner.

[0070] For ease of understanding, the following example is used to assist in the explanation: Assume that X1 = liner humidity value, X2 = ambient humidity value. The internal reference humidity value is 60%RH, and the ambient reference humidity value is 70%RH. RH is the unit of humidity. Generally, the indoor relative humidity is ≤60%RH, which is dry and comfortable, not humid. When X1≤60%RH and X2≤70%RH, the condensation circulation channel enters the external circulation mode, and the door ventilation mechanism switches to the air intake mode.

[0071] See also Figure 5 The fifth embodiment of the ventilation method for a washing appliance in the embodiment of the present invention includes:

[0072] When the internal humidity value is less than or equal to the internal reference humidity value, the ambient humidity value is compared with the ambient reference humidity value, and further includes:

[0073] 501. If the ambient humidity value is greater than the ambient reference humidity value, the condensation circulation channel is switched to the external circulation mode through the internal and external circulation switching mechanism, and the door ventilation mechanism is switched to the closed mode.

[0074] In this embodiment, when the internal humidity value is less than or equal to the internal reference humidity value and the ambient humidity value is greater than the ambient humidity value, this condition indicates that the internal humidity value is at a normal level and the ambient humidity value is at a humid level (i.e., the air in the sterilization liner is in a dry and comfortable state, and the air in the environment is in a humid state). In order to prevent water vapor from the external environment from entering the sterilization cavity, the air intake channel and the exhaust channel of the door ventilation mechanism need to be closed (i.e., switched to the closed mode) to prevent water vapor from entering the sterilization cavity from the door ventilation mechanism, and then the external circulation mode of the condensation circulation channel is used to discharge excess moisture in the sterilization cavity to form a one-way exhaust effect, prevent oversaturation, and maintain a suitable working environment for the sterilization liner.

[0075] For ease of understanding, the following example is used to assist in explanation: Assume that X1 = liner humidity value, X2 = ambient humidity value. The internal reference humidity value is 60%RH, and the ambient reference humidity value is 70%RH. RH is the unit of humidity. Generally, the indoor relative humidity is ≤60%RH, which is dry and comfortable, not humid. When X1≤60%RH and X2>70%RH, the condensation circulation channel enters the external circulation mode, and the door ventilation mechanism switches to the default mode (not working).

[0076] See also Figure 6 The sixth embodiment of the ventilation method for a washing appliance in the embodiment of the present invention includes:

[0077] If the internal humidity value and the ambient humidity value meet the preset humidity condition, the condensation circulation channel is switched to the external circulation mode through the internal and external circulation switching mechanism, including:

[0078] 601. When the internal humidity value is greater than the internal reference humidity value, the ambient humidity value is compared with the ambient reference humidity value;

[0079] 602. If the ambient humidity value is less than or equal to the ambient reference humidity value, the condensation circulation channel is kept in the internal circulation mode through the internal and external circulation switching mechanism until the internal humidity value is less than or equal to the internal reference humidity value, and then the door ventilation mechanism is cyclically switched between the air intake mode and the exhaust mode according to the preset switching frequency.

[0080] In this embodiment, when the internal humidity value is greater than the internal reference humidity value and the ambient humidity value is less than or equal to the ambient humidity value, this condition indicates that the internal humidity value is at a humid level and the ambient humidity value is at a normal level (i.e., the air in the sterilization liner is in a humid state and the air in the environment is in a dry and comfortable state), the sterilization liner is switched to the internal circulation mode, and the gas is separated from the water vapor by using the condensation circulation channel until the internal humidity value is less than or equal to the internal reference humidity value. This can effectively control the humidity in the sterilization liner and avoid affecting the sterilization effect due to improper humidity. In addition, by cyclically switching between the air intake mode and the exhaust mode through the door ventilation mechanism, the humidity in the sterilization liner can be kept in dynamic balance, so that new air can frequently flow into the sterilization liner, thereby forming a clean and dry air environment in the sterilization liner.

[0081] See also Figure 7 The seventh embodiment of the ventilation method for a washing appliance in the embodiment of the present invention includes:

[0082] When the internal humidity value is greater than the internal reference humidity value, the ambient humidity value is compared with the ambient reference humidity value, and further includes:

[0083] 701. If the ambient humidity value is greater than the ambient reference humidity value, the condensation circulation channel is kept in the internal circulation mode through the internal and external circulation switching mechanism until the internal humidity value is less than or equal to the internal reference humidity value. Then the condensation circulation channel is switched to the external circulation mode through the internal and external circulation switching mechanism, and the door ventilation mechanism is switched to the exhaust mode.

[0084] In this embodiment, when the internal humidity value is greater than the internal reference humidity value and the ambient humidity value is greater than the ambient reference humidity value, this condition indicates that the internal humidity value and the ambient humidity value are both at a humid level (i.e., the air in the sterilization liner and the air in the environment are both in a humid state), the sterilization liner is switched to the internal circulation mode, and the gas is separated from the water vapor by using the condensation circulation channel until the internal humidity value is less than or equal to the internal reference humidity value. This can effectively control the humidity in the sterilization liner and avoid affecting the sterilization effect due to improper humidity. In addition, by coordinating the exhaust mode of the door ventilation mechanism and the external circulation mode of the condensation circulation channel, the moisture in the sterilization liner can be discharged unidirectionally from the external circulation mode and the exhaust mode, which not only avoids the water vapor in the environment from entering the sterilization liner, but also ensures that the sterilization liner can quickly discharge the water vapor.
