It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0042] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 , an embodiment of the tableware disinfection method of a washing machine in the embodiment of the present invention includes:
[0043] The tableware disinfection system of a washing machine comprises: applied to the tableware disinfection system of a washing machine, the tableware disinfection system of a washing machine comprises: a control device and a sterilization liner electrically connected to the control device, an internal and external circulation switching mechanism, a dry air intake component and a condensation exhaust component; the dry air intake component is connected to the air inlet of the sterilization liner, the condensation exhaust component is connected to the exhaust port of the sterilization liner, the dry air intake component and the condensation exhaust component are connected through the internal and external circulation switching mechanism, an internal circulation channel is formed between the sterilization liner, the internal and external circulation switching mechanism, the dry air intake component and the condensation exhaust component, and the internal and external circulation switching mechanism is used to switch the switch state of the internal circulation channel;
[0044] 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.
[0045] The switching principle of the internal and external circulation switching mechanism is as follows: when the sterilization inner tank requires an internal circulation mode, the switching motor is used to drive the gate piece to rotate relative to the center of the circle until the gate piece covers the semicircular window and the blocking edge is aligned with the bottom of the condensation chamber. The condensation chamber is directly connected between the fans at the left and right ends. The water vapor in the dishwasher inner tank is condensed through the condensation chamber and then returned to the inner tank; when the sterilization inner tank requires an external circulation mode, the switching motor is used to drive the gate piece to rotate 180° relative to the center of the circle, the gate piece is away from the semicircular window, and the baffle moves to the center line position of the semicircular window. At this time, the baffle divides the condensation chamber into two left and right unit chambers, and the airflow discharged from the sterilization inner tank is discharged through half of the semicircular window, while the external airflow is sucked in by the other half of the semicircular window and transported back to the sterilization inner tank.
[0046] 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.
[0047] The tableware disinfection method of a washing appliance comprises the steps of:
[0048] 101. Obtain the working mode of the sterilization liner. If the sterilization liner is in the steam sterilization mode, obtain the real-time pressure information of the sterilization liner, and determine whether the real-time pressure information is less than or equal to the pressure threshold;
[0049] 102. When the real-time pressure information is less than or equal to the pressure threshold, the sterilization liner is kept in steam sterilization mode according to the preset working conditions;
[0050] In this embodiment, it is first confirmed whether the sterilization liner has entered the steam sterilization mode. Then, after confirming that it is in the steam sterilization mode, the pressure information of the sterilization liner is monitored in real time and compared with the pressure threshold. This can ensure that the equipment operates within a safe pressure range, avoid equipment damage or safety accidents caused by excessive pressure, prevent the internal pressure of the sterilization liner from being too high, causing water vapor to overflow from the door gap, and reduce the risk of water vapor retained in the gap between the fuselage and the door body.
[0051] 103. After the steam sterilization mode is completed, the sterilization liner is switched to the internal circulation mode through the internal and external circulation switching mechanism, so that the high-temperature and high-humidity steam circulates along the direction of the internal circulation channel between the condensation exhaust component and the dry air intake component in turn;
[0052] 104. Obtain real-time temperature information of the sterilization liner, and determine whether the real-time temperature information is less than a temperature threshold;
[0053] 105. When the real-time temperature information is less than the temperature threshold, the drying air intake component and the condensation exhaust component are controlled to be closed, and the real-time humidity information of the sterilization liner is obtained;
[0054] 106. Determine whether the real-time humidity information is less than or equal to the humidity threshold. If the real-time humidity information is less than or equal to the temperature threshold, output a disinfection completion signal.
[0055] In this embodiment, after the sterilization liner completes steam sterilization, the high temperature and high humidity gas in the sterilization liner needs to be processed, and the internal and external circulation switching mechanism is used to switch the sterilization liner to the internal circulation mode to prevent the high temperature and high humidity gas from overflowing and injuring people. The high temperature and high humidity gas is circulated through the condensation exhaust component and the dry air intake component for safe processing. The high temperature and high humidity gas is condensed and cooled by the condensation exhaust component to reduce the temperature of the gas, and the wall surface of the internal circulation channel is used to collide with the gas to further achieve the effect of water vapor separation. At the same time, the high temperature and high humidity gas is also condensed and cooled by the dry air intake component. The gas is heated and dried to remove water vapor in the high-temperature and high-humidity gas to achieve a dehumidification effect. In addition, with the cooperation of the condensation exhaust component and the dry air intake component, the sterilization liner is also dried and disinfected to improve the disinfection effect of the sterilization liner; in the process of safely handling the high-temperature and high-humidity gas, the temperature information and humidity information of the sterilization liner are monitored in real time to determine whether the high-temperature and high-humidity gas has reached a safe range. By reducing the temperature information and humidity information to a safe value, the user can be prevented from being harmed by high-temperature and high-humidity steam when opening the door, thereby ensuring the user's safety.
[0056] In an embodiment of the present invention, in the steam sterilization mode, by real-time monitoring of the pressure information of the sterilization liner and comparing it with the pressure threshold, it is possible to ensure that the equipment operates within a safe pressure range, form an effect of dynamic balance of internal pressure, avoid equipment damage or safety accidents caused by excessive pressure, and prevent the internal pressure of the sterilization liner from being too high, causing water vapor to overflow from the door gap; and, after the steam sterilization is completed, the sterilization liner is connected to the internal circulation channel through the internal and external circulation switching mechanism, and the high-temperature and high-humidity gas is condensed and cooled and dried and dehumidified by the condensation exhaust component and the dry air intake component, thereby reducing the temperature and humidity of the gas, and reducing the air temperature and humidity in the sterilization liner to safe values, effectively preventing the user from being harmed by high-temperature and high-humidity steam when opening the door, thereby ensuring the user's safety.
[0057] See also Figure 2 The second embodiment of the tableware disinfection method of a washing machine in the embodiment of the present invention comprises:
[0058] The internal and external circulation switching mechanism is provided with an external circulation air inlet and an external circulation air outlet;
[0059] In this embodiment, the external circulation air inlet and the external circulation air outlet are respectively connected to an external fan; the external fan is used to realize air supply and exhaust.
[0060] After the step of determining whether the real-time humidity information is less than or equal to the humidity threshold, the following step is further included:
[0061] 201. If the real-time humidity information is greater than the humidity threshold, the internal and external circulation switching mechanism is controlled to switch to the external circulation mode, so that the external circulation air inlet is connected to the drying air inlet component and the external circulation air outlet is connected to the condensing exhaust component, so that the steam flows along the one-way channel formed by the external circulation air inlet, the drying air inlet component, the condensing exhaust component and the external circulation air outlet;
[0062] 202. Obtain the external circulation humidity information of the sterilization inner tank, and compare the external circulation humidity information with the humidity threshold. If the external circulation humidity information is less than or equal to the humidity threshold, the external circulation mode is turned off through the internal and external circulation switching mechanism, and a disinfection completion signal is output.
[0063] In this embodiment, when the temperature reaches the safe value but the humidity has not yet reached the safe value, the external circulation mode is required to further dry the gas in the sterilization liner; the system can monitor the humidity information in real time and compare it with the preset humidity threshold. When the temperature reaches the safe value but the detected humidity still exceeds the threshold, the system will automatically switch to the external circulation mode to reduce the humidity; through the design of the one-way channel, the steam can efficiently flow from the external circulation air inlet to the dry air intake component, then pass through the condensation exhaust component, and finally be discharged through the external circulation exhaust port, ensuring the efficiency of air flow and the drying effect; when the system detects that the external circulation humidity information is less than or equal to the humidity threshold (that is, the humidity also reaches the safe value), the system will automatically turn off the external circulation mode to prevent excessive drying, keep the ambient humidity within an appropriate range, and also prevent bacteria from entering the sterilization liner; by precisely controlling the humidity, unnecessary energy consumption is reduced, which helps to save energy and reduce emissions and meet environmental protection requirements; in addition, in this way, the safety of users when opening the door is effectively improved, and the user experience is improved.
[0064] See also Figure 3 The third embodiment of the tableware disinfection method of a washing machine in the embodiment of the present invention includes:
[0065] The tableware disinfection system for washing appliances also includes a switch door body electrically connected to the control device and capable of opening and closing automatically;
[0066] If the real-time humidity information is greater than the humidity threshold, the internal and external circulation switching mechanism is controlled to switch to the external circulation mode, so that the external circulation air inlet is connected to the drying air inlet component and the external circulation air outlet is connected to the condensation exhaust component, so that the steam flows along the one-way channel formed by the external circulation air inlet, the drying air inlet component, the condensation exhaust component and the external circulation air outlet, and further includes:
[0067] 301. If the real-time humidity information is greater than the humidity threshold, the switch door is controlled to open to a preset angle according to a preset door opening angle, so that the steam in the sterilization tank can escape outside the switch door.
[0068] In this embodiment, when the temperature reaches a safe value but the humidity has not yet reached a safe value, in order to accelerate the drying of the inner tank, the system will control the switch door to automatically open at a certain opening angle to release the humid gas inside the sterilization tank. By cooperating with the external circulation channel, the moisture in the sterilization tank can be more effectively discharged, further ensuring that the humidity is maintained within a safe range, thereby improving the sterilization efficiency and the safety of equipment operation.
[0069] See also Figure 4 The fourth embodiment of the tableware disinfection method of a washing machine in the embodiment of the present invention includes:
[0070] The tableware disinfection system for a washing machine further comprises a door ventilation mechanism electrically connected to the control device, the door ventilation mechanism being arranged on the switch door and being connected to the sterilization inner container; the door ventilation mechanism is used to adjust the exhaust state or the air intake state of the sterilization inner container;

[0072] After the step of determining whether the real-time pressure information is less than or equal to the pressure threshold, the following step is further included:
[0073] 401. When the real-time pressure information is greater than the pressure threshold, the door ventilation mechanism is switched to the exhaust state, so that the sterilization liner is kept in the exhaust state within the preset pressure reduction time;
[0074] 402. Obtain the real-time pressure reduction information of the sterilization liner, and compare the real-time pressure reduction information with the pressure threshold. If the real-time pressure reduction information is less than or equal to the pressure threshold, control the door ventilation mechanism to close the exhaust state, so that the sterilization liner enters the pressure maintaining state.
[0075] In this embodiment, when it is detected that the real-time pressure information is greater than the pressure threshold, the door ventilation mechanism will switch to the exhaust state, effectively preventing safety problems that may be caused by excessive pressure; by adjusting the exhaust state, the pressure in the sterilization tank can be quickly reduced, the steam sterilization process can be accelerated, and the disinfection efficiency can be improved; in the steam sterilization mode, the pressure information is monitored in real time and compared with the preset pressure threshold to ensure that the sterilization tank is disinfected under an appropriate pressure state, thereby ensuring the disinfection effect, so that the sterilization tank forms a dynamic pressure stabilization effect; by precisely controlling the exhaust and pressure maintenance state of the sterilization tank, unnecessary energy consumption can be reduced, achieving the effect of energy saving and consumption reduction; reasonable pressure control and exhaust mechanism help to reduce damage to the internal structure of the tableware disinfection system of the washing appliance, thereby extending the service life of the equipment.
[0076] See also Figure 5 The fifth embodiment of the method for disinfecting tableware of a washing appliance in the embodiment of the present invention comprises:
[0077] The method of obtaining the working mode of the sterilization liner, if the sterilization liner is in the steam sterilization mode, obtains the real-time pressure information of the sterilization liner, and determines whether the real-time pressure information is less than or equal to the pressure threshold, and also includes:
[0078] 501. Obtain the real-time loading capacity of the sterilization liner, and calculate the steam output and working conditions according to the real-time loading capacity.
[0079] In this embodiment, the steam output and working conditions are determined by detecting the real-time loading volume of the sterilization inner tank, thereby ensuring that the steam can complete the disinfection of tableware in the smallest unit, reducing unnecessary energy consumption, contributing to energy conservation and emission reduction, and meeting environmental protection requirements.
[0080] For ease of understanding, the following example is used to assist in explanation: Assuming that the inner pot of a standard full load of tableware (17 sets) has a steam output time of 3 minutes and a sterilization time of 10 minutes.
[0081] See also Figure 6 The sixth embodiment of the method for disinfecting tableware of a washing appliance in the embodiment of the present invention comprises:
[0082] The step of obtaining the working mode of the sterilization liner, if the sterilization liner is in the steam sterilization mode, obtaining the real-time pressure information of the sterilization liner, and determining whether the real-time pressure information is less than or equal to the pressure threshold, includes:
[0083] 601. Obtain the real-time steam temperature and real-time steam humidity in the sterilization liner. If the real-time steam temperature and the real-time steam humidity both meet the preset steam conditions, determine that the working mode of the sterilization liner is the steam sterilization mode, and obtain the real-time pressure information of the sterilization liner to determine whether the real-time pressure information is less than or equal to the pressure threshold;
[0084] 602. If either the real-time steam temperature or the real-time steam humidity does not meet the preset steam condition, it is determined that the working mode of the sterilization liner is the sterilization drying mode, and the sterilization liner is kept in the sterilization drying mode according to the preset drying condition.
[0085] In this embodiment, whether the sterilization liner enters the steam sterilization mode is determined by monitoring whether the steam temperature data and steam humidity data in the sterilization liner reach the standard of steam sterilization (i.e., whether the temperature value and humidity content value meet the standard). If the sterilization liner adopts steam sterilization, the subsequent steam treatment process is performed. If the sterilization liner does not meet the above conditions, the sterilization liner only enters the sterilization drying mode, and it only uses the external circulation drying mode to dry and disinfect the sterilization liner. There is no problem of high-temperature and high-humidity gas, and there is no need for corresponding steam treatment. In this way, unnecessary energy consumption can be reduced, achieving the effect of energy saving and consumption reduction.
[0086] See also Figure 7 The seventh embodiment of the method for disinfecting tableware of a washing appliance in the embodiment of the present invention comprises:
[0087] After the steam sterilization mode is completed, the sterilization inner tank is switched to the inner circulation mode through the inner and outer circulation switching mechanism, so that the high-temperature and high-humidity steam circulates along the direction of the inner circulation channel between the condensation exhaust component and the dry air intake component in sequence, and also includes:
[0088] 701. After the steam sterilization mode is completed, the door ventilation mechanism is controlled to switch to the air intake state to deliver dry cold air to the sterilization liner.
[0089] In this embodiment, by switching the door ventilation mechanism to the air intake state, dry cold air can be effectively delivered to the sterilization inner tank, thereby accelerating the dehumidification and cooling effect of the high-temperature and high-humidity gas, forming a superimposed effect with the internal circulation channel, and improving the dehumidification and cooling effect of the internal circulation channel.
