Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0034] The present application will now be described in detail with reference to specific embodiments.

[0035] Figure 1 This is a schematic diagram of the structure of a washing device provided in an embodiment of this application.

[0036] like Figure 1 As shown, the washing device includes a washing chamber 100 and an exhaust assembly 200. The washing device can be a dishwasher, a washing machine or other washing equipment.

[0037] The washing chamber 100 is disposed inside the main body of the washing equipment, serving as the working space of the washing equipment. For example, the washing chamber 100 can have various shapes, such as square, spherical, hemispherical, or other irregular shapes, to adapt to different design and functional requirements. Within the washing chamber 100, the washing equipment can provide one or more functions such as washing, drying, and storage for the items to be processed.

[0038] The exhaust assembly 200 includes a first air inlet 210, a second air inlet 220, and an exhaust outlet 230. The first air inlet 210 communicates with the washing chamber 100, while the second air inlet 220 and the exhaust outlet 230 are respectively connected to the outside of the washing chamber. The first air inlet 210, being directly connected to the washing chamber 100, allows air from inside the washing chamber 100 to enter the exhaust assembly 200 and be discharged to the outside environment via the exhaust outlet 230, removing moisture, heat, or odors from the washing chamber 100. The second air inlet 220, located outside the washing chamber 100, allows outside air to enter the exhaust assembly 200, enabling fresh air from outside to mix with the air entering the washing chamber 100. This helps regulate the temperature and humidity of the exhaust gas from the washing equipment or helps dilute odors in the exhaust gas.

[0039] The exhaust assembly 200 also includes a first fan 240, a detection element 250, and a regulating valve 260. The first fan 240 and the detection element 250 are both located at the end near the exhaust port 230. The first fan 240 provides power and can draw in air. Its location at the end near the exhaust port 230 can push the gas in the exhaust assembly 200 out of the exhaust port to the external environment. At the same time, the negative pressure formed in the exhaust assembly 200 can push the gas in the washing chamber 100 into the exhaust assembly 200 through the first air inlet 210 and / or push the air in the external environment into the exhaust assembly 200 through the second air inlet 220, thereby controlling the gas flow and its direction within the exhaust assembly 200. Ventilation holes or ventilation slits may also be provided inside the washing chamber 100. These ventilation holes or ventilation slits connect the washing chamber 100 to the external environment, so that after the first fan 240 draws in the gas, the washing chamber 100 forms a negative pressure, which pushes the outside air into the washing chamber 100 through the ventilation holes or ventilation slits to maintain the pressure balance inside the washing chamber 100.

[0040] The detection element 250 is disposed at the same end as the first fan 240, located at the exhaust port 230, ensuring that the detection element 250 can contact the gas discharged through the exhaust assembly 200, thereby realizing gas parameter detection. In some embodiments, the detection element 250 can be disposed downstream (rear end) of the first fan 240, closer to the exhaust port 230, in order to more accurately detect the gas parameters of the gas discharged from the exhaust port 230. In some embodiments, the detection element 250 may include a temperature and humidity sensor 251 and / or an odor sensor 252. The temperature and humidity sensor 251 is used to detect the temperature and humidity information of the gas. Its temperature sensor portion can use thermocouples, thermistors, or similar technologies to measure the gas temperature; its humidity sensor portion can detect the water vapor content in the air, usually by measuring the relative humidity of the air. By detecting these data, the moisture content (absolute humidity, dew point temperature, etc.) in the gas discharged from the exhaust assembly 200 can be determined. Odor sensors are used to detect and analyze odor molecules in the air, specifically by detecting certain chemicals, such as volatile organic compounds (VOCs) and specific chemicals produced by spoiled food. These chemicals are often associated with unpleasant odors, and by detecting the concentration of these odor molecules, it can be determined whether the gas contains unpleasant odors or the concentration of odors.

[0041] The regulating valve 260 is used to control the opening degree of the first air inlet 210 and / or the second air inlet 220 in the exhaust assembly 200. The regulating valve 260 can open the first air inlet 210 (opening degree greater than 0) and completely close the second air inlet 220 (opening degree equal to 0), allowing only the gas in the washing chamber 100 to enter the exhaust assembly 200, thereby enabling the detection element 250 to detect the gas in the washing chamber 100. Alternatively, the regulating valve 260 can completely close the first air inlet 210 (opening degree equal to 0) and open the second air inlet 220 (opening degree greater than 0), allowing only ambient air to enter the exhaust assembly 200, thereby enabling the detection element 250 to detect ambient gases. The regulating valve 260 can open the first air inlet 210 (opening degree greater than 0) and the second air inlet 220 (opening degree greater than 0), so that the gas in the washing chamber 100 and the external ambient gas mix in the exhaust assembly 200. By adjusting the opening ratio between the first air inlet 210 and the second air inlet 220, the concentration of the gas in the washing chamber 100 in the exhaust assembly is controlled, so that the concentration of the gas discharged from the diluted washing chamber 100 is within the threshold range, avoiding condensation or obvious unpleasant odor in the discharged gas.

[0042] In some embodiments, such as Figure 1 As shown, the regulating valve 260 can be configured as a valve plate structure, located at the intersection of the first air inlet 210 pipe and the second air inlet 220 pipe. One end of the valve plate of the regulating valve 260 is connected to the exhaust assembly 200, and the other end can move between end A and end B. When the valve plate of the regulating valve 260 is located at end A, the first air inlet 210 is fully open (opening degree 100%), and the second air inlet 220 is fully closed (opening degree 0%). When the valve plate of the regulating valve 260 is located at end B, the first air inlet 210 is fully closed (opening degree 0%), and the second air inlet 220 is fully open (opening degree 100%). When the valve plate of the regulating valve 260 is located between end A and end B, both the first air inlet 210 and the second air inlet 220 are open. As the valve plate moves, the opening degree of the first air inlet 210 increases, and the opening degree of the second air inlet 220 decreases; conversely, the smaller the opening degree of the first air inlet 210, the larger the opening degree of the second air inlet 220. In some embodiments, the valve plate of the regulating valve 260 can be controlled by a stepper motor to achieve stepless adjustment of the valve plate between end A and end B.

[0043] like Figure 2 As shown, in some embodiments, the washing device further includes a heating assembly 300 for heating the gas within the washing chamber 100. Exemplarily, the heating assembly 300 may be configured based on one or more heating methods selected from hot air heating, radiant heating, and induction heating.

[0044] For example, hot air heating heats air by heating elements in heating assembly 300 and blows the hot air into washing chamber 100 using a fan; radiant heating does not rely on air flow, but emits heat directly into washing chamber 100 through radiation sources (such as heating wires) in heating assembly 300; induction heating uses the electromagnetic field of heating assembly 300 to heat metal elements in washing chamber 100, thereby indirectly heating the interior of washing chamber 100.

[0045] like Figure 2 As shown, in some embodiments, the heating assembly 300 is configured using hot air heating, including a third air inlet 310 and an air outlet 320. The third air inlet 310 and the air outlet 320 are respectively connected to the washing chamber 100. The heating assembly 300 is equipped with a second fan 330 and a heating element 340. The second fan 330 is located inside the heating assembly 300 and can promote the air circulation in the washing chamber 100, pushing the air in the washing chamber 100 into the heating assembly 300 from the third air inlet 310. At this time, the heating element 340 located inside the heating assembly 300 heats the flowing air. The heated air is blown into the washing chamber 100 from the air outlet 320 by the second fan 330, thereby forming a circulating heating inside the washing chamber 100. In some embodiments, to ensure heating efficiency, the third air inlet 310 can be located above the washing chamber 100, the air outlet 320 can be located below the washing chamber 100, the second fan 330 can be located near the air outlet 320, and the heating element 340 can be located downstream (rear end) of the second fan 330, closer to the air outlet 320. This allows the hot air heated by the heating element 340 to directly enter the washing chamber 100, and because hot air has a low density, it will rise, effectively transferring heat to the cool air above the washing chamber 100, resulting in faster and more even heat circulation and higher heating efficiency.

[0046] In some embodiments, the washing device is a dishwasher, and the exhaust assembly 200 and the heating assembly 300 are respectively disposed on both sides of the washing chamber 100 to avoid the heating assembly 300 interfering with the detection element 250 in the exhaust assembly 200.

[0047] The washing equipment also includes a controller ( Figure 1 and Figure 2 (Not shown in the image) The controller can execute corresponding control commands to realize various functions of the washing equipment; the controller can be connected to functional components such as the first fan 240, the detection element 250, the regulating valve 260, the second fan 330, and the heating element 340 to realize the switching and other control of each functional component.

[0048] In this embodiment, the washing device can use an exhaust assembly to expel moisture, heat, or odors from the washing chamber. The detection element can monitor the parameters of the expelled gas, thus achieving dehumidification and deodorization within the washing chamber. Furthermore, the washing device can utilize the detection element in the exhaust assembly to detect both the gas parameters within the washing chamber and the gas parameters of the external environment, providing accurate and comprehensive monitoring of both internal and external gas parameters while saving on hardware costs.

[0049] Next, we will combine Figure 1 and Figure 2 The provided washing equipment, taking the washing equipment or its controller performing gas detection as an example, illustrates the gas detection method provided in this application. After the drying process in the washing equipment, the gas concentration in the washing chamber is relatively low, which can affect the accuracy of gas measurement during the storage stage. The gas detection method provided in this embodiment can further improve the detection accuracy of gas parameters in the washing equipment chamber during the storage stage. Please refer to... Figure 3 This is a schematic flowchart illustrating a gas detection method for a washing device provided in an exemplary embodiment of this application. Figure 3 As shown, when the washing equipment is in the storage stage, this gas detection method includes the following steps:

[0050] S301, control the first fan to run at a first speed so that the gas in the washing chamber enters the exhaust assembly from the first air inlet and is discharged from the exhaust port after passing through the detection element.

[0051] Specifically, when the washing equipment is in storage, the first fan is controlled to run at a first speed. The first fan begins to draw gas from the exhaust assembly and discharge it to the outside through the exhaust port. This allows the gas inside the washing chamber to enter the exhaust assembly through the first air inlet and come into contact with the detection element, enabling the detection element to detect the gas inside the washing chamber. Using this method, the detection element does not need to be installed inside the washing chamber to detect the gas parameters. Therefore, the detection element is not subjected to the harsh environment of high temperature and high humidity inside the washing chamber, ensuring the detection accuracy of the element, extending its lifespan, and reducing the hardware cost of gas detection.

[0052] The first speed is the speed at which the first fan is used to detect gas parameters within the washing chamber during the storage phase. This first speed is lower than the operating speed of the fan during the drying process. The aforementioned operating speed is the standard speed at which the fan operates to expel the hot and humid air from the washing chamber during the drying process (drying phase). This fan can be the first fan or other exhaust or intake fans. The aforementioned operating speed is the optimal speed defined based on equipment design, drying efficiency requirements, and safety standards to ensure drying effect and long-term stable operation of the equipment.

[0053] In this embodiment, to accurately detect the gas parameters inside the washing chamber during the storage stage, the first fan operates at a lower speed during the storage stage compared to the operating speed used during the drying stage. This reduces airflow turbulence within the washing chamber, thereby stabilizing the gas concentration inside the chamber. By controlling the first fan to operate at a lower speed, the gas inside the washing chamber can diffuse more rapidly to the detection element, increasing detection efficiency and improving detection accuracy. For example, if the first fan operates too slowly, the gas diffusion rate inside the washing chamber may be too slow, resulting in excessively long detection time and low detection efficiency. If the first fan operates too fast, the gas inside the washing chamber may be discharged into the outside environment too quickly, creating negative pressure in the washing chamber. This causes excessive fresh air to rush in through the ventilation holes or slits of the washing chamber, diluting the gas inside the washing chamber. Consequently, the gas parameters detected by the detection element will be inconsistent with the actual environment inside the washing chamber, affecting detection accuracy.

[0054] The first rotational speed can be either a fixed value or a dynamic value. For example, the first rotational speed can be determined based on the degree of change in the detection result of the detection element. When the change in the detection result of the detection element within a first preset time period is less than a first preset threshold, it indicates that the first fan has fully extracted the gas in the washing chamber into the exhaust assembly, and the first rotational speed is reduced. If the change in the detection result of the detection element within the first preset time period is still less than the first preset threshold, the first rotational speed is further reduced until the minimum set rotational speed (which can be 0) is reached. The first rotational speed can be specifically set according to the specific implementation scenario.

[0055] In some embodiments, the first air inlet is not always open. Therefore, before controlling the first fan to run at the first speed, the regulating valve is first adjusted to the first state so that the first air inlet is open and the second air inlet is closed.

[0056] Adjusting the regulating valve to the first state allows the first air inlet to be fully or partially opened, while the second air inlet is completely closed. Since the first air inlet is connected to the washing chamber and the second air inlet is connected to the outside of the washing chamber, in the first state, the exhaust assembly is only connected to the inside of the washing chamber and isolated from the outside. At this time, the detection element in the exhaust assembly can detect the gas parameters inside the washing chamber.

[0057] For example, such as Figure 4 As shown, when the regulating valve 260 has a valve plate structure, the valve plate controlling the regulating valve 260 is adjusted to end A, which is the first state. At this time, the first air inlet 210 is opened and the second air inlet 220 is closed.

[0058] S302, after the first fan runs at the first speed for the first duration, acquire the first gas parameter information detected by the detection element.

[0059] Specifically, during the drying process, the washing equipment introduces a large amount of fresh air into the washing chamber and exhausts it through the exhaust assembly. Because the gas inside the washing chamber is diluted by the outside fresh air, its concentration is relatively low, but it gradually increases over time until it reaches a relatively stable state. If the gas parameter information obtained immediately after the first fan starts operating is used as the gas parameter information inside the washing chamber, it may not accurately reflect the true gas concentration inside the washing chamber, and the detection accuracy will be affected. Therefore, it is necessary to run the first fan at the first speed for the first duration, allowing the gas concentration inside the washing chamber to stabilize, before obtaining the first gas parameter information detected by the detection element. This first gas parameter information can accurately characterize the true gas parameter information inside the washing chamber.

[0060] The first duration can be a fixed value (e.g., 0-30 min) or a dynamic value. For example, the first duration can be determined based on the degree of change in the detection results of the detection element. When the change in the detection results of the detection element is less than a second preset threshold, it indicates that the first fan has met the first duration, the gas state in the washing chamber is relatively stable, and the current detection result of the detection element can be obtained as the first gas parameter information. If the first rotation speed is a dynamic value, it can be determined that the first fan has met the first duration when the first rotation speed is reduced to the lowest set speed and the change in the detection results of the detection element is less than the second preset threshold, and the current detection result of the detection element can be obtained as the first gas parameter information. The first duration can be specifically set according to the specific implementation scenario.

[0061] In some embodiments, the detection element includes a temperature and humidity sensor and / or an odor sensor, and the first gas parameter information includes temperature and humidity information detected by the temperature and humidity sensor, and / or odor molecule information detected by the odor sensor.

[0062] Specifically, the method described in this embodiment can use the aforementioned detection element to accurately measure the moisture content and odor inside the washing chamber, enabling accurate monitoring of the internal environment of the washing chamber during the storage stage. This facilitates intelligent control during the storage stage, effectively controlling odors and moisture, and improving the user experience.

[0063] In this embodiment, the application controls a regulating valve to open the first air inlet and close the second air inlet. Then, by controlling the first fan to run at a first speed for a first duration, the application can acquire the first gas parameter information detected by the detection element. Since the first air inlet is open and the second air inlet is closed, the exhaust assembly is only connected to the inside of the washing chamber; therefore, the detected first gas parameter information is the gas parameter inside the washing chamber. Furthermore, by controlling the speed and running time of the first fan, the detection accuracy of the gas parameters inside the washing equipment chamber during the storage stage can be effectively improved, ensuring the optimal storage environment for washed items and providing users with a more efficient and intelligent user experience.

[0064] In some embodiments, the method further includes: controlling the heating assembly to operate for a second duration so that the heating assembly heats the gas in the washing chamber.

[0065] Specifically, after adjusting the regulating valve to the first state, the first air inlet opens while the second air inlet closes, allowing the gas in the washing chamber to diffuse into the exhaust assembly. The heating assembly heats the gas in the washing chamber; the increased temperature increases the velocity of gas molecules, resulting in a more even distribution in the air. Simultaneously, heating makes water vapor and odor molecules more active, especially since the volatility of certain odor molecules increases with temperature, making them easier to diffuse into the exhaust assembly for detection. This heating process increases the concentration of water vapor and odor molecules in the air within the washing chamber (responding to a stable state more quickly) and results in a more uniform distribution, improving the detection sensitivity of the sensing element.

[0066] In some embodiments, the heating method of the heating component includes, but is not limited to, hot air heating, radiant heating, and induction heating. For example, Figure 2 As shown, taking hot air heating as an example, the heating process specifically includes: controlling the second fan and heating element in the heating assembly to run for a second period of time, so that the gas in the washing chamber enters the heating assembly from the third air inlet, and after being heated by the heating element, returns to the washing chamber from the air outlet.

[0067] Specifically, a second fan is used to drive the gas inside the washing chamber to circulate internally, and the heating element heats the gas entering the heating assembly, so that the heated gas is more fully and evenly distributed in the washing chamber, and the gas concentration recovers to a stable state more quickly. This makes the gas parameters (such as moisture content and odor) detected by the detection element more accurate and consistent with the actual internal environment of the washing chamber.

[0068] The second duration can be set according to the first duration. For example, the second duration can be the same as the first duration, or the time when the regulating valve is adjusted to the first state can be used as the start time of the second duration, and the end time of the first duration can be used as the end time of the second duration. The heating temperature of the heating component should be sufficient to promote the diffusion of gas molecules without affecting the performance of the components of the washing equipment or the properties of the substance being tested. The second duration and heating temperature can be set according to the specific implementation scenario and are not limited here.

[0069] In some embodiments, the method further includes controlling the first fan to stop operating for a third duration.

[0070] Specifically, during the drying stage of the washing equipment, the first fan or other exhaust or intake fans operate at the aforementioned speed. At this time, the gas inside the washing chamber is diluted by fresh outside air, failing to reflect the true environment within the chamber. If the first fan is directly controlled to operate at the first speed, although lower than the fan's operating speed, a small amount of fresh outside air can still enter through the ventilation holes or slits of the washing chamber. Furthermore, the continuous influence of the fan on the gas inside the chamber may lead to uneven distribution and insufficient evaporation of water vapor and odor molecules, thus affecting the efficiency of restoring the environment to a stable state. Therefore, stopping the first fan for a third duration (e.g., more than 1 minute) allows sufficient time for the evaporation and diffusion of water vapor and odor molecules before gas parameter detection, improving detection efficiency while reducing energy consumption.

[0071] In some embodiments, the method further includes: adjusting the regulating valve to a second state to close the first air inlet and open the second air inlet; controlling the first fan to run at a second speed to allow gas from outside the washing chamber to enter the exhaust assembly from the second air inlet and exit from the exhaust port through the detection element; and acquiring second gas parameter information detected by the detection element; wherein the first speed is less than the second speed.

[0072] Specifically, in order to achieve intelligent control during the storage phase of the washing equipment, while ensuring that the detection elements can accurately detect gas parameters (such as moisture content and odor) inside the washing chamber, it is also necessary to determine the gas parameters of the external environment as the reference parameters for intelligent control.

[0073] When detecting gas parameters in the external environment, adjusting the regulating valve to the second state completely closes the first air inlet while fully or partially opening the second air inlet. Since the first air inlet is connected to the washing chamber and the second air inlet is connected to the outside of the washing chamber, in the second state, the exhaust assembly is only connected to the external environment and isolated from the inside of the washing chamber. At this time, the detection element in the exhaust assembly can detect the gas parameters in the external environment.

[0074] For example, such as Figure 5 As shown, when the regulating valve 260 has a valve plate structure, the valve plate controlling the regulating valve 260 is adjusted to end B, which is the second state. At this time, the first air inlet 210 is closed and the second air inlet 220 is open.

[0075] To increase detection efficiency, when detecting gas parameters in the external environment of the washing chamber, the first fan can operate at a preset second speed to accelerate airflow within the exhaust assembly. This allows ambient air to quickly enter the exhaust assembly from the second air inlet, pass through the detection element, and exit from the exhaust outlet, where it is detected, ensuring detection efficiency. The aforementioned second gas parameter information represents the gas parameters in the external environment of the washing chamber. When detecting gas parameters inside the washing chamber, the first fan can operate at a reduced first speed to reduce airflow turbulence within the washing chamber, ensuring stable gas concentration and improving detection accuracy. It is understood that the first speed should be lower than the second speed. Reducing the first fan speed prioritizes ensuring the detection accuracy of gas parameters within the washing chamber. The first and second speeds can be specifically set according to the specific implementation scenario.

[0076] In some embodiments, the above-mentioned acquisition of the second gas parameter information detected by the detection element includes: after the first fan runs at a second speed for a fourth duration, acquiring the second gas parameter information detected by the detection element; wherein the first duration is longer than the fourth duration.

[0077] Specifically, to ensure the accuracy of the gas parameters detected by the detection element, the second gas parameter information should only be acquired after the first fan has been running at the second speed for four hours, allowing the gas state inside the exhaust assembly to stabilize and become consistent with the external environment. The fourth time period is the time required for the gas state inside the exhaust assembly to stabilize, and this can be set according to the specific implementation scenario.

[0078] When detecting the gas parameters inside the washing chamber, the speed of the first fan is reduced. In order to ensure that the gas concentration inside the washing chamber can return to a stable state and that the detection element can accurately detect the gas parameters inside the washing chamber, the detection time should be appropriately increased to improve the detection accuracy. That is, the first time should be greater than the fourth time.
