[0002] Food cooking is a complex chemical reaction process that produces not only solid oil fume pollution but also gaseous oil fume pollution, commonly known as foul odor or unpleasant smell. These are composed of various volatile gases, abbreviated as VOCs (Volatile Organic Compounds).

[0003] Currently, a common technology for controlling VOCs pollution is to use high-ozone ultraviolet light beams to irradiate odorous gases, causing them to decompose and remove the odor. VOCs purification devices are generally installed at the outlet of the fume exhaust duct. When the exhaust fan is detected to be running, the VOCs purification device starts and purifies the VOCs. However, current VOCs purification devices cannot automatically identify their own faults and protect the equipment, and maintenance personnel cannot promptly understand the device's operating status.

[0013] Optionally, the operating state of each purification component is determined based on whether the power is less than the second power threshold, including:

[0015] If the current purification power is greater than or equal to the second power threshold, then the corresponding purification component is determined to be in normal working condition.

[0016] Optionally, after controlling the purification component to shut down when the component's operating state is abnormal, the method further includes:

[0017] If the current voltage value is greater than the first voltage threshold and / or the current current value is greater than the first current threshold, then a purification component fault information is generated indicating that the current voltage value is too high and / or the current current value is too high.

[0018] Optionally, after controlling the purification component to shut down when the component's operating state is abnormal, the method further includes:

[0019] If the current voltage value is less than the second voltage threshold and / or the current current value is less than the second current threshold, then a purification component fault information is generated indicating that the current voltage value is too low and / or the current current value is too low.

[0020] Optionally, the VOCs purification device detection method further includes:

[0021] When the component is in normal working condition, the purification component that is in normal working condition is turned on.

[0022] Optionally, the VOCs purification device includes a three-way purification component;

[0023] The activation of at least one purification component in the VOCs purification device is determined based on the current airflow setting of the exhaust fan, including:

[0024] If the current airflow level is 3, then all three purification components in the VOCs purification device will be turned on.

[0025] If the current airflow level is 2, then control any two of the purification components in the VOCs purification device to turn on;

[0026] If the current airflow level is 1, then control any one of the purification components in the VOCs purification device to turn on;

[0027] If the current airflow setting is 0, then all three purification components will be turned off.

[0031] A memory communicatively connected to the at least one processor; wherein,

[0032] The memory stores a computer program that can be executed by the at least one processor, which enables the at least one processor to perform the VOCs purification device detection method according to any embodiment of the present invention.

[0045] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0046] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0047] Example 1

[0048] Figure 1 This invention provides a flowchart of a VOCs purification device detection method according to Embodiment 1. This embodiment is applicable to fault detection of VOCs purification devices in the catering industry. The VOCs purification device detection method can be executed by the VOCs purification device, which can be implemented in hardware and / or software. See [link to documentation]. Figure 2 The diagram illustrates a usage scenario for the VOCs purification device 300. This VOCs purification device 300 can be configured in a central purification system. A fume hood 100 and a damper 200 are installed in the user's kitchen. The fume hood 100 has a control button for the exhaust fan 400. Pressing the button opens the damper 200, and the exhaust fan 400 starts exhausting smoke at a corresponding frequency, expelling kitchen fumes through the fume hood 100. The VOCs purification device 300 activates its corresponding purification capacity based on the detected fume levels. This VOCs purification device includes at least two purification components, such as... Figure 1 As shown, the detection method for this VOCs purification device includes:

[0049] S110. Determine the start of at least one purification component in the VOCs purification device based on the current air volume setting of the exhaust fan, and after the purification component starts, obtain the current voltage and current value of each purification component.

[0050] The air volume setting of the exhaust fan refers to the air volume at which the exhaust fan removes smoke. The air volume setting is determined by the model of the exhaust fan. The current air volume setting of the exhaust fan is obtained by the VOCs purification device receiving and parsing the broadcast command from the exhaust fan. Optionally, the air volume setting of the exhaust fan is 0-3, in which case the current air volume setting of the exhaust fan is 0, 1, 2, or 3.

[0051] It is understood that the number of purification components in a VOCs purification device can be the same as the number of airflow settings of the exhaust fan. That is, if the exhaust fan has airflow settings of 0-3, then the VOCs purification device has three purification components. Alternatively, the number of purification components in a VOCs purification device can be greater than the number of airflow settings of the exhaust fan. That is, if the exhaust fan has airflow settings of 0-2, then the VOCs purification device has three purification components. This embodiment does not impose any restrictions on this.

[0052] Specifically, taking the exhaust fan's airflow settings of 0-3 as an example, the VOCs purification device can be equipped with three purification components. When the current airflow setting is 3, all three purification components in the VOCs purification device are turned on; when the current airflow setting is 2, any two purification components in the VOCs purification device are turned on; when the current airflow setting is 1, any one purification component in the VOCs purification device is turned on; and when the current airflow setting is 0, all three purification components are turned off.

[0053] As can be seen, since each purification component in the VOCs purification device can adopt the same structure, when the current air volume setting is such that not all purification components are activated, any combination of purification components can be selected for activation. That is, when the current air volume setting is 2, any two purification components can be selected for activation.

[0054] Furthermore, after the purification components are started, the voltage and current of each activated purification component are collected. That is, if one purification component is activated, the voltage and current values ​​of that purification component are collected; if two purification components are activated, the voltage and current values ​​of both purification components are collected.

[0055] The current voltage value of each purification component can be measured in real time by the purification component voltage detection module in the VOCs purification device, and the current current value of each purification component can be measured in real time by the purification component current detection module in the VOCs purification device.

[0056] S120. Determine the working status of each purification component based on the current voltage and current values, and control the purification component to shut down when the working status is abnormal. Broadcast the purification component fault information corresponding to the abnormal working status to the exhaust fan.

[0057] Based on the above, the current purification power of each purification component can be calculated according to the current voltage and current values ​​using the existing power calculation formula. Then, the operating status of each purification component can be determined according to the current purification power of each purification component.

[0058] Each purification component can be classified as either normal or abnormal. If the current purification power is greater than a first power threshold, the corresponding purification component is classified as abnormal. If the current purification power is less than or equal to the first power threshold, it is further determined whether the current purification power is less than a second power threshold. If the current purification power is less than the second power threshold, the corresponding purification component is classified as abnormal. If the current purification power is greater than or equal to the second power threshold, the corresponding purification component is classified as normal.

[0059] In this embodiment, if a component malfunction is determined when the current purification power exceeds a first power threshold, the purification component fault information corresponding to the component malfunction can be further determined by using the current voltage and current values ​​of the purification component that is determined to be malfunctioning. Specifically: if the current voltage value of the purification component that is determined to be malfunctioning is greater than the first voltage threshold, then a purification component fault information indicating that the current voltage value of the purification component that is determined to be malfunctioning is too high is generated; if the current current value of the purification component that is determined to be malfunctioning is greater than the first current threshold, then a purification component fault information indicating that the current current value of the purification component that is determined to be malfunctioning is too high is generated; if both the current voltage value and the current current value of the purification component that is determined to be malfunctioning are greater than the first voltage threshold and the first current threshold, then a purification component fault information indicating that both the current voltage value and the current current value of the purification component that is determined to be malfunctioning are too high is generated.

[0060] If a component is determined to be abnormal when its current purification power is less than or equal to a first power threshold and less than a second power threshold, then the component's operating state can be further determined by the current voltage and current values ​​of the determined abnormal component. Specifically: if the current voltage value of the determined abnormal component is less than the second voltage threshold, then a component fault information of "current voltage value too low" is generated; if the current current value of the determined abnormal component is less than the second current threshold, then a component fault information of "current current value too low" is generated; if both the current voltage and current values ​​of the determined abnormal component are less than the second voltage threshold, then a component fault information of "current voltage value too low" and "current current value too low" is generated.

[0061] Based on the above embodiments, regardless of whether the purification component fault information includes one or a combination of fault information such as current voltage too high, current current too high, current voltage too low, and current current too low, it can be broadcast to the exhaust fan in real time, so that the exhaust fan can understand the working status of the VOCs purification device in a timely manner and adjust its own exhaust situation accordingly.

[0062] The technical solution of this invention determines the activation of at least one purification component in the VOCs purification device based on the current airflow level of the exhaust fan. After activation, the current voltage and current values ​​of each purification component are acquired. The operating status of each purification component is determined based on these values. If a component is found to be malfunctioning, it is controlled to shut down. The fault information of the corresponding malfunctioning component is broadcast to the exhaust fan. This invention solves the problem of VOCs purification devices failing to automatically identify faults, enabling automatic identification of the operating status and faults of purification components, timely handling of VOCs purification device malfunctions, and improved safety of the VOCs purification device.

[0063] Example 2

[0064] Figure 3 This is a flowchart of a VOCs purification device detection method provided in Embodiment 2 of the present invention. Based on the above embodiments, this embodiment determines the operating status of each purification component and its fault information based on the current voltage and current values ​​of each purification component, providing an optional implementation method. For example... Figure 3 As shown, the detection method for this VOCs purification device includes:

[0065] S210. Determine the start of at least one purification component in the VOCs purification device based on the current air volume setting of the exhaust fan, and after the purification component starts, obtain the current voltage and current value of each purification component.

[0066] See Figure 4 and Figure 6 The VOCs purification device shown has three sets of lamp assemblies installed in its purification components. (See attached image.) Figure 5 As shown, each lamp assembly consists of two ultraviolet lamps and a corresponding ballast. The controller in the purification assembly can control the power supply to the ballast of each lamp assembly, enabling the ultraviolet lamps in each assembly to emit ultraviolet light beams to irradiate odorous gases, causing them to decompose and thus purifying VOCs. Furthermore, the controller in the purification assembly can also be equipped with protection functions implemented in hardware and / or software to protect the VOCs purification device.

[0067] S220. Determine the current purification power based on the current voltage and current values.

[0068] S230. Determine whether the current purification power is greater than the first power threshold. If yes, proceed to step S231; otherwise, proceed to step S240.

[0069] The first power threshold is the maximum power limit of the purification component when it is turned on. The first power threshold can be pre-calibrated according to the properties of the purification component, etc. In this embodiment, no specific value of the first power threshold is restricted.

[0070] S231. Determine that the working status of the corresponding purification component is abnormal, and shut down the corresponding purification component. Then proceed to step S232.

[0071] S232. If the current voltage value of the purification component that is determined to be abnormal is greater than the first voltage threshold and / or the current current value is greater than the first current threshold, then generate purification component fault information indicating that the current voltage value of the purification component that is determined to be abnormal is too high and / or the current current value is too high, and execute step S250.

[0072] The first voltage threshold is the maximum normal voltage limit corresponding to the purification component that is determined to be abnormal. The first voltage threshold can be pre-calibrated based on information such as the actual attributes of the purification component that is abnormal. In this embodiment, no specific value of the first voltage threshold is restricted.

[0073] The first current threshold is the maximum normal current limit corresponding to the purification component that is determined to be abnormal. The first current threshold can be pre-calibrated based on information such as the actual attributes of the purification component that is abnormal. In this embodiment, no specific value of the first current threshold is restricted.

[0074] Specifically, if the current voltage value of a purification component that is determined to be abnormal is greater than the first voltage threshold, it means that the purification component that is determined to be abnormal is an overvoltage fault, and correspondingly, a purification component fault information is generated indicating that the current voltage value of the purification component that is determined to be abnormal is too high.

[0075] If the current value of a purification component that is determined to be abnormal is greater than the first current threshold, it means that the purification component that is determined to be abnormal is experiencing an overcurrent fault, and a purification component fault information indicating that the current current value of the purification component that is determined to be abnormal is too high is generated.

[0076] S240. Determine whether the current purification power is greater than the second power threshold. If yes, proceed to step S241; otherwise, proceed to step S243.

[0077] The second power threshold is the minimum power limit of the purification component when it is turned on. The second power threshold can be pre-calibrated according to the properties of the purification component, etc. In this embodiment, no specific value of the second power threshold is restricted.

[0078] S241. Determine that the working status of the corresponding purification component is abnormal, and shut down the corresponding purification component. Then proceed to step S242.

[0079] S242. If the current voltage value is less than the second voltage threshold and / or the current current value is less than the second current threshold, generate purification component fault information indicating that the current voltage value is too low and / or the current current value is too low, and execute step S250.

[0080] The second voltage threshold is the minimum normal voltage limit corresponding to the purification component that is determined to be abnormal. The second voltage threshold can be pre-calibrated based on information such as the actual attributes of the purification component that is abnormal. In this embodiment, no specific value of the second voltage threshold is restricted.

[0081] The second current threshold is the minimum normal current limit corresponding to the purification component that is determined to be abnormal. The second current threshold can be pre-calibrated based on information such as the actual attributes of the purification component that is abnormal. In this embodiment, no specific value of the second current threshold is restricted.

[0082] Specifically, if the current voltage value of a purification component that is determined to be abnormal is less than the second voltage threshold, it means that the purification component that is determined to be abnormal is undervoltage fault, and correspondingly generates purification component fault information indicating that the current voltage value of the purification component that is determined to be abnormal is too low.

[0083] If the current value of a purification component that is determined to be abnormal is less than the second current threshold, it means that the purification component that is determined to be abnormal is undercurrent fault, and correspondingly generates purification component fault information that the current current value of the purification component that is determined to be abnormal is too low.

[0084] S243. Determine that the corresponding purification component is in normal working condition, and keep the purification component in normal working condition turned on.

[0085] S250. Broadcast the purification component fault information corresponding to the component whose working status is abnormal to the smoke exhaust fan.

[0086] The technical solution of this invention can accurately identify the fault type of the VOCs purification device by identifying and judging the current, voltage and power of each purification component. At the same time, the VOCs purification device has a self-protection function and has corresponding protection measures when the VOCs purification device has a safety fault, thereby improving the safety performance of the VOCs purification device and realizing the effect of automatic fault identification and self-protection of the VOCs purification device.

The display module displays the current operating status of each purification component locally. Additionally, a fuse is added before each group of purification components at the front end of the purification component control circuit for hardware circuit protection in case of software protection failure, improving the safety of the VOCs purification equipment.
