Description

Technical Field

[0001] This application relates to the field of smart appliances, and in particular to an adaptive air pressure balancing method for smart appliances and the smart appliances themselves. Background Technology

[0002] As people's living standards improve and technologies such as the internet, big data, artificial intelligence, and voice interaction become more widespread, traditional lifestyles are gradually changing, and the use of home appliances is increasingly moving towards intelligentization. While bringing more convenience to users, the functions of various home appliances are also becoming more diversified.

[0003] To enhance the intelligence and ease of use of home smart appliances, automatic cleaning functions are often included. During automatic cleaning, heating and hot air drying are typically required. However, during these stages, the gas inside the appliance expands due to heat, resulting in high pressure. In the subsequent cooling stage, the internal gas contracts, creating negative pressure. These different cleaning stages can cause drastic fluctuations in the internal air pressure of the smart appliance, leading to door seal failure.

[0004] There is currently no effective solution to the problem that the internal air pressure of smart appliances can fluctuate drastically during different cleaning stages, causing the door seal to fail. Summary of the Invention

[0005] This embodiment provides an adaptive air pressure balancing method and a smart appliance to solve the problem of drastic fluctuations in internal air pressure during different cleaning stages of the smart appliance in related technologies.

[0006] Firstly, this embodiment provides an adaptive air pressure balancing method for a smart appliance. The smart appliance's cavity contains an adjustment device equipped with multiple micro-pressure sensors, which are used to detect the pressure state at different locations within the cavity. The cavity has a door, which is fitted with a door seal and a door lock. The method includes:

[0007] Under different cleaning conditions of the smart appliance, the internal air pressure of the cavity and the door sealing force in the cavity are obtained through the micro-pressure sensor; the door sealing force is the sealing force provided by the door seal strip on the door in the cavity;

[0008] The safety margin of the gas pressure inside the cavity is calculated based on the internal air pressure, the sealing force of the door, the contact area between the gas inside the cavity and the door, and the locking force of the door lock.

[0009] Based on the aforementioned safety margin, the air inlet / outlet of the regulating device is controlled and adjusted to correct the internal air pressure of the cavity.

[0010] Through the above steps, using a preset door sealing constraint model, the safety margin of the air pressure inside the cavity is calculated based on the internal air pressure, door sealing force, contact area, and door lock locking force. Then, based on the safety margin, the regulating device is controlled to achieve adaptive air pressure balance inside the cavity of the smart appliance.

[0011] In some embodiments, the safety margin of the internal air pressure is calculated based on the internal air pressure, the door sealing force, the contact area between the gas in the cavity and the door, and the locking force of the door lock, including:

[0012] The product of the contact area and the internal air pressure of the cavity, plus the sealing force of the door, is determined to be the internal force of the cavity.

[0013] The safety margin of the air pressure inside the cavity is determined based on the difference between the internal force of the cavity and the locking force of the door lock.

[0014] Through the above steps, based on multiple physical quantities reflecting the internal pressure of the cavity in the smart appliance, the safety margin of the current internal air pressure is determined. Then, based on the safety margin, it is determined whether the internal air pressure of the cavity needs to be adjusted to avoid the cavity from generating high / low pressure under different cleaning conditions.

[0015] In some embodiments, the regulating device includes an exhaust assembly; determining the safety margin of the air pressure inside the cavity based on the difference between the internal force of the cavity and the locking force of the door lock includes:

[0016] If the safety margin of the air pressure inside the cavity does not exceed a preset safety threshold, a positive pressure risk signal is generated.

[0017] Based on the positive pressure risk signal, the exhaust assembly is activated to exhaust air from the cavity.

[0018] If, after following the above steps, it is determined that the safety margin of the air pressure inside the cavity does not exceed the preset safety threshold, it indicates that the air pressure inside the cavity is too high and needs to be reduced. For example, by controlling the exhaust component in the regulating device, the cavity can be vented to stabilize the air pressure inside, thereby ensuring that the safety margin exceeds the preset safety threshold.

[0019] In some embodiments, the regulating device further includes a respirator; the step of controlling the opening of the exhaust assembly to exhaust air from the cavity based on the positive pressure risk signal further includes:

[0020] Based on the positive pressure risk signal, the respirator is activated to assist the exhaust assembly in venting the cavity.

[0021] Through the above steps, the respirator is mainly used to balance the air pressure inside and outside the cavity of the smart appliance, prevent water backflow, and assist in drainage. When the air pressure inside the cavity is too high and pressure reduction is required, the respirator's auxiliary exhaust component can be used to reduce the cavity air pressure, which helps to improve the control efficiency of air pressure balance.

[0022] In some embodiments, the regulating device includes an air intake assembly; determining the safety margin of the air pressure inside the cavity based on the difference between the internal force of the cavity and the locking force of the door lock further includes:

[0023] If the safety margin of the air pressure inside the cavity exceeds a preset safety threshold, determine whether the internal air pressure of the cavity exceeds a preset air pressure.

[0024] If it is determined that the internal air pressure of the cavity does not exceed the preset air pressure, the air intake component is opened to replenish air to the cavity.

[0025] Through the above steps, if the safety margin of the air pressure inside the cavity exceeds the preset safety threshold, it indicates that the current air pressure inside the cavity is not too high. In order to improve the accuracy of air pressure balance, it is necessary to further determine whether the internal air pressure of the cavity is too low. If the internal air pressure of the cavity does not exceed the preset air pressure, it indicates that the air pressure inside the cavity is too low and needs to be pressurized. Specifically, the air pressure inside the cavity is increased by opening the air intake component to achieve air pressure balance inside the cavity.

[0026] In some embodiments, the regulating device further includes a heating component; the step of controlling the opening of the air intake component to replenish air to the cavity when it is determined that the internal air pressure of the cavity does not exceed the preset air pressure further includes:

[0027] If the internal air pressure of the cavity does not exceed the preset air pressure, the heating component is activated to circulate and heat the cavity while replenishing it with air.

[0028] By following the steps above, when the internal air pressure of the cavity is too low and pressurization is required, the heating component can be combined with the air intake component to increase the cavity air pressure, which helps to improve the control efficiency of air pressure balance.

[0029] In some embodiments, a temperature sensor is also disposed within the cavity of the smart appliance; the method further includes:

[0030] The temperature of the cavity of the smart appliance is obtained through the temperature sensor;

[0031] The door sealing force is determined based on the cavity temperature and the preset initial door sealing force.

[0032] Through the above steps, since the door sealing force is provided by the door seal strip in the cavity, and the sealing force of the door seal strip is affected by the ambient temperature due to the limitations of the material and service life, the temperature information inside the cavity can be detected, and the door sealing force can be corrected according to the temperature information, which helps to improve the accuracy of the air pressure balance inside the cavity.

[0033] Secondly, this embodiment provides a smart appliance that employs the adaptive air pressure balance method for smart appliances as described in the first aspect. The smart appliance is one of a dishwasher or a steam oven.

[0034] Thirdly, this embodiment provides an electronic device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the adaptive air pressure balancing method for the intelligent electrical appliance described in the first aspect.

[0035] Fourthly, this embodiment provides a storage medium storing a computer program that, when executed by a processor, implements the adaptive air pressure balancing method for intelligent electrical appliances described in the first aspect.

[0045] To better understand the purpose, technical solution, and advantages of this application, the application is described and illustrated below in conjunction with the accompanying drawings and embodiments.

The terms "first," "second," "third," etc., used in this application are merely to distinguish similar objects and do not represent a specific order of objects.

[0047] In existing smart appliances, such as dishwashers, the internal air pressure fluctuates drastically during the operation cycle, especially during the heating and washing and hot air drying stages. This can cause door sealing failure. Specifically, during washing and heating or hot air drying, the gas inside the cavity expands due to heat, resulting in high pressure. This pressure may overcome the locking force of the door seal and lock, causing the door to pop open unexpectedly and interrupting the washing / drying process. In the subsequent cooling stage, the internal gas contracts, creating negative pressure, which causes the door to be sucked in, making it difficult for the user to open.

[0048] To address the aforementioned issues, existing technologies typically involve installing breathers and exhaust assemblies in the left and right cavities of the dishwasher, with vents on the breathers. However, these breathers and exhaust assemblies often employ straight-through pipe structures, where the high-humidity, high-speed airflow directly impacts the breather diaphragm, easily causing airflow shearing and standing wave resonance, resulting in continuous, sharp whistling and booming noises. Furthermore, the exhaust fans often operate at a fixed speed, unable to adapt to minor pipe blockages or delayed exhaust conditions, lacking adaptive pressure regulation logic and failing to achieve pressure balance within the dishwasher's cavity. Moreover, the use of passively fixed pressure relief vents provides only a simple, reactive pressure relief, lacking real-time pressure sensing and closed-loop dynamic airflow control logic. Therefore, existing technologies cannot achieve pressure balance within the cavity of a smart appliance by simply installing breathers and exhaust assemblies.

[0049] Based on this, this embodiment provides an adaptive air pressure balancing method for smart appliances, which is applied within the cavity of the smart appliance. Figure 1 This is a flowchart of the adaptive air pressure balance method for smart appliances provided in the embodiments of this application, such as... Figure 1 As shown, the process includes the following steps:

[0050] Step S110: Under different cleaning conditions of the smart appliance, the internal air pressure of the cavity and the sealing force of the door in the cavity are obtained through a micro-pressure sensor; the sealing force is the sealing force provided by the door seal strip on the door in the cavity.

[0051] The intelligent appliance's cavity contains an adjustment device equipped with multiple micro-pressure sensors, which are used to detect the pressure status at different locations within the cavity. The cavity is equipped with a door, which has a door seal and a door lock. The adjustment device includes an exhaust assembly, an intake assembly, and a breather. Figure 2 This is a schematic diagram of the structure of the respirator and exhaust assembly inside the intelligent electrical cavity provided in this specific embodiment; Figure 3 This is a schematic diagram of the air intake assembly within the cavity of the intelligent electrical appliance provided in this specific embodiment; see reference. Figure 2 and Figure 3 A respirator 11, an exhaust assembly 12, and an air intake assembly 13 are respectively installed in the inner liner of the cavity 10 of the smart appliance. An air intake fan 131 is installed on the air intake assembly 13. By adjusting the speed of the air intake fan 131, the rate at which the air pressure inside the cavity 10 is increased can be further controlled.

[0052] Micro-pressure sensors are installed at the hot air inlet (i.e., the air intake assembly), the respirator outlet, and the exhaust assembly outlet to collect physical quantities related to cavity pressure in real time.

[0053] Step S120: Calculate the safety margin of the air pressure inside the cavity based on the internal air pressure, the sealing force of the door, the contact area between the gas inside the cavity and the door, and the locking force of the door lock.

[0054] The system establishes a closed-loop mechanism based on internal air pressure, door sealing force, the contact area between the gas inside the cavity and the door, and the locking force of the door lock. This mechanism senses changes in pressure within the dishwasher cavity and automatically adjusts the internal air pressure. Specifically, it dynamically adjusts the amount of gas inside the cavity based on the physical quantity of internal pressure, thereby increasing the door sealing force F. 密 Internal air pressure P 气 Locking force F of the door lock 锁 The following door seal force-based quantitative constraint model is satisfied:

[0055] ;

[0056] Where t represents the running time of the smart appliance, and A represents the contact area between the gas inside the cavity and the door.

[0057] If the pressure-related state quantities in the cavity of a current smart appliance satisfy the quantitative constraint model of the sealing force, it indicates that the safety margin is high and the cavity pressure is in a stable state; otherwise, pressurization is required to achieve pressure balance in the cavity.

[0058] Step S130: Based on a safety margin, control and adjust the air inlet / outlet of the regulating device to correct the internal air pressure of the cavity.

[0059] Based on this safety margin, the air intake / exhaust of the regulating device (intake assembly, breather, exhaust assembly) is dynamically adjusted to adjust the internal gas volume or pressure value, ensuring that the door sealing force constraint model always holds true.

[0060] Through the above steps, using a preset door sealing constraint model, the safety margin of the air pressure inside the cavity is calculated based on the internal air pressure, door sealing force, contact area, and door lock locking force. Then, based on the safety margin, the regulating device is controlled to achieve adaptive air pressure balance inside the cavity of the smart appliance.

[0061] In some embodiments, the safety margin of the internal air pressure is calculated based on the internal air pressure, the door sealing force, the contact area between the gas inside the cavity and the door, and the locking force of the door lock, including:

[0062] The product of the contact area and the internal air pressure of the cavity, plus the sealing force of the door, is the internal force of the cavity.

[0063] The safety margin of the air pressure inside the cavity is determined based on the difference between the internal force of the cavity and the locking force of the door lock.

[0064] Through the above steps, based on the preset door sealing constraint model, the safety margin of the current air pressure in the cavity is determined according to multiple physical quantities reflecting the internal pressure of the cavity in the smart appliance. Then, based on the safety margin, it is determined whether the internal air pressure of the cavity needs to be adjusted to avoid the cavity from generating high / low pressure under different cleaning conditions.

[0065] In some embodiments, the regulating device includes an exhaust assembly; determining a safety margin for the gas pressure inside the cavity based on the difference between the internal force of the cavity and the locking force of the door lock includes:

[0066] If the safety margin of the air pressure inside the cavity does not exceed the preset safety threshold, a positive pressure risk signal is generated.

[0067] Based on the positive pressure risk signal, control the opening of the exhaust assembly to exhaust air from the cavity.

[0068] If, after following the above steps, it is determined that the safety margin of the air pressure inside the cavity does not exceed the preset safety threshold, it indicates that the air pressure inside the cavity is too high and needs to be reduced. For example, by controlling the exhaust component in the regulating device, the cavity can be vented to stabilize the air pressure inside, thereby ensuring that the safety margin exceeds the preset safety threshold.

[0069] In some embodiments, the regulating device further includes a respirator; and controls the opening of the exhaust assembly to exhaust air from the cavity based on a positive pressure risk signal, and also includes:

[0070] Based on the positive pressure risk signal, control the activation of the respirator to assist the exhaust assembly in venting the cavity.

[0071] Through the above steps, the respirator is mainly used to balance the air pressure inside and outside the cavity of the smart appliance, prevent water backflow, and assist in drainage. When the air pressure inside the cavity is too high and pressure reduction is required, the respirator's auxiliary exhaust component can be used to reduce the cavity air pressure, which helps to improve the control efficiency of air pressure balance.

[0072] In some embodiments, the regulating device includes an air intake assembly; and determines a safety margin for the air pressure inside the cavity based on the difference between the force inside the cavity and the locking force of the door lock, further including:

[0073] If the safety margin of the gas pressure inside the cavity exceeds the preset safety threshold, determine whether the internal gas pressure of the cavity exceeds the preset gas pressure.

[0074] If the internal air pressure of the cavity does not exceed the preset air pressure, the air intake component is activated to replenish the cavity with air.

[0075] Through the above steps, if the safety margin of the air pressure inside the cavity exceeds the preset safety threshold, it means that the current air pressure inside the cavity is not too high. In order to improve the accuracy of air pressure balance, it is necessary to further judge whether the internal air pressure of the cavity is too low. If the internal air pressure of the cavity does not exceed the preset air pressure, it means that the air pressure inside the cavity is too low and needs to be pressurized. Specifically, the air pressure inside the cavity is increased by opening the air intake component to achieve air pressure balance inside the cavity.

[0076] In some embodiments, the regulating device further includes a heating component; and when it is determined that the internal air pressure of the cavity does not exceed a preset air pressure, it controls the opening of the air intake component to replenish air to the cavity, and further includes:

[0077] If the internal air pressure of the cavity does not exceed the preset air pressure, the heating component is activated to circulate and heat the cavity while replenishing it with air.

[0078] By following the steps above, when the internal air pressure of the cavity is too low and pressurization is required, the heating component can be combined with the air intake component to increase the cavity air pressure, which helps to improve the control efficiency of air pressure balance.

[0079] In some embodiments, a temperature sensor is also disposed within the cavity of the smart appliance; the method further includes:

[0080] The cavity temperature of smart appliances is obtained through temperature sensors;

[0081] The door sealing force is determined based on the cavity temperature and the preset initial door sealing force.

[0082] Through the above steps, since the door sealing force is provided by the door seal strip in the cavity, and the sealing force of the door seal strip is affected by the ambient temperature due to the limitations of the material and service life, the temperature information inside the cavity can be detected, and the door sealing force can be corrected according to the temperature information, which helps to improve the accuracy of the air pressure balance inside the cavity.

[0083] The method embodiments provided in this example can be executed on a terminal, computer, or similar computing device. For example, it can run on a terminal.

The processor 102 executes various functional applications and data processing by running the computer programs stored in the memory 104, thereby implementing the aforementioned method.

[0086] This embodiment provides a smart appliance that uses the adaptive air pressure balance method of the smart appliance in the above embodiment to ensure dynamic air pressure balance in the cavity of the smart appliance; the smart appliance is a dishwasher, a steam oven, or any other smart appliance that requires cleaning of a sealed cavity.

[0087] The present embodiment will be described and explained below through specific examples.

[0088] Taking dishwashers as an example of smart appliances, Figure 5 This is a flowchart of the dishwasher adaptive air pressure balance method according to a specific embodiment of this invention. Figure 5As shown, when the dishwasher's self-cleaning system starts, it enters the wash / dry program and reads the current cavity temperature T based on the temperature sensor installed inside the dishwasher cavity. Then, it adjusts the door sealing force according to temperature compensation. The adjusted door sealing force... Expressed as a formula:

[0089] ;

[0090] in, This indicates the preset initial sealing force of the sealing strip on the cavity door, and T represents the current temperature of the cavity. This represents the correction factor.

[0091] Subsequently, based on the modified door sealing force The safety margin, ΔF, is calculated using the following formula:

[0092] ;

[0093] in, Indicates the sealing force of the door. This indicates the air pressure inside the cavity. The value A represents the locking force of the door lock, and A represents the contact area between the gas inside the cavity and the door.

[0094] If the safety margin ΔF does not exceed the preset safety threshold, i.e. ΔF≤ safety threshold, it indicates that the cavity pressure is in a positive pressure risk state, which triggers the cavity depressurization strategy. Specifically, the depressurization is forced out by turning on the exhaust assembly fan, and the depressurization can be assisted by a respirator.

[0095] If the safety margin ΔF exceeds the preset safety threshold, i.e., ΔF > safety threshold, it is necessary to further determine the internal gas pressure of the cavity. Is it less than 0?

[0096] When determining △F > safety threshold and When the pressure is less than 0, it indicates that the cavity air pressure is in a negative pressure risk state, which triggers the cavity pressure replenishment strategy. Specifically, the fan of the air intake component is turned on to replenish the air, and a heating component such as PTC (Power and Temperature Cycling) can be selected to circulate heating and pressurize.

[0097] After applying the above pressure balancing strategies, when ΔF > safety threshold and When the value is ≥0, the current state of the actuator (i.e., the regulating device) is maintained to achieve dynamic pressure balance within the cavity.
