A purification system, a formaldehyde removal purifier, and its control method and apparatus.

Abstract

This invention discloses a purification system, a formaldehyde removal purifier, and its control method and device. The control method for the formaldehyde removal purifier includes: when the purifier is in standby mode, acquiring preset operating parameters of the electrical equipment; determining whether the electrical equipment is in heating mode based on the operating parameters; and when the electrical equipment is in heating mode, controlling the purifier to switch from standby mode to operating mode. This is because when the electrical equipment is in heating mode, the indoor temperature increases. Since the volatilization rate of formaldehyde increases with temperature, the increased indoor temperature leads to a faster release rate of formaldehyde, potentially causing the indoor formaldehyde concentration to exceed the standard. The above technical solution allows the purifier to automatically switch from standby mode to operating mode, accelerating the formaldehyde removal process and making it suitable for applications with slower formaldehyde release rates.

Description

Technical Field

[0001] This invention relates to the field of electrical equipment control technology, specifically to a purification system, a formaldehyde removal purifier, and its control method and device. Background Technology

[0002] Formaldehyde has been confirmed by the International Agency for Research on Cancer as a direct carcinogen. As early as 2010, the WHO listed formaldehyde as a major indoor pollutant. Long-term exposure to formaldehyde can cause adverse symptoms such as dizziness, fever, insomnia, and decreased immunity.

[0003] After a new house is renovated, it usually needs to be ventilated or treated with a formaldehyde-removing air purifier for a period of time before moving in. Using a formaldehyde-removing air purifier is one of the most effective ways to remove formaldehyde.

[0004] In the initial period after a new house is renovated or when there is new furniture, formaldehyde is released rapidly, so formaldehyde-removing air purifiers need to run for a longer time. During this period, the purifier can be controlled to start and stop according to user instructions. However, as time goes on, the release rate of formaldehyde slows down, and for most of the time, the indoor formaldehyde concentration meets national standards, so it is not necessary to turn on the air purifier. However, in some situations, it is still necessary to turn on the air purifier. Because formaldehyde is a colorless, odorless, but irritating gas, the national standard stipulates that the safe indoor formaldehyde concentration is 0.1 mg / m³. 3 Even if the formaldehyde concentration exceeds the standard, most people will not feel it, so users cannot know when they need to turn on the formaldehyde removal air purifier. Summary of the Invention

[0005] In view of this, embodiments of the present invention provide a purification system, a formaldehyde removal purifier, and a control method and apparatus thereof, so as to provide a control method for turning on the formaldehyde removal purifier, so that the formaldehyde removal purifier can be automatically turned on when the formaldehyde concentration may exceed the standard, and the formaldehyde removal purifier can be applied to application scenarios where the formaldehyde release rate is slow.

[0006] According to a first aspect, embodiments of the present invention provide a control method for a formaldehyde removal purifier, comprising the following steps: when the formaldehyde removal purifier is in standby mode, acquiring preset operating parameters of the electrical device; determining whether the electrical device is in heating mode based on the operating parameters; and when the electrical device is in heating mode, controlling the formaldehyde removal purifier to enter operating mode from standby mode.

[0007] Specifically, before obtaining the preset operating parameters of the electrical equipment, the process includes: determining whether the formaldehyde removal purifier has established a communication connection with the electrical equipment that has a heating function for air; when the formaldehyde removal purifier establishes a communication connection with the electrical equipment, the step of obtaining the preset operating parameters of the electrical equipment is executed.

[0008] Specifically, the control method for the formaldehyde removal purifier also includes: when the formaldehyde removal purifier and the electrical device have not established a communication connection, determining whether an operating command has been received; when the operating command is received, controlling the formaldehyde removal purifier to enter the operating state from the standby state.

[0009] Specifically, when controlling the formaldehyde removal purifier to enter the operating state from the standby state, or after controlling the formaldehyde removal purifier to enter the operating state from the standby state, the method further includes: acquiring the detection data of the formaldehyde removal purifier; and determining the operating parameters of the formaldehyde removal purifier based on the detection data of the formaldehyde removal purifier.

[0010] Specifically, after controlling the formaldehyde removal purifier to enter the operating state from the standby state, the method further includes: continuing to acquire the operating parameters of the electrical device; determining whether the electrical device is in a non-heating mode based on the operating parameters; and when the electrical device is in a non-heating mode, controlling the formaldehyde removal purifier to enter the standby state from the operating state or controlling the formaldehyde removal purifier to enter the shutdown state from the operating state.

[0011] Specifically, before controlling the formaldehyde removal purifier to enter standby mode from the running state or to enter shutdown mode from the running state, the method further includes: determining whether the formaldehyde removal purifier is in running mode; when the formaldehyde removal purifier is in running mode, controlling the formaldehyde removal purifier to enter standby mode from the running state or to enter shutdown mode from the running state.

[0012] According to a second aspect, embodiments of the present invention also provide a control device for a formaldehyde removal purifier, including an acquisition module, a processing module, and a control module; when the formaldehyde removal purifier is in standby mode, the acquisition module is used to acquire preset operating parameters of the electrical device; the processing module is used to determine whether the electrical device is in heating mode based on the operating parameters; when the electrical device is in heating mode, the control module is used to control the formaldehyde removal purifier to enter the operating state from the standby state.

[0013] According to a third aspect, embodiments of the present invention also provide a formaldehyde removal purifier, including a memory and a processor, wherein the memory and the processor are communicatively connected to each other, the memory stores computer instructions, and the processor executes the computer instructions to perform the control method of the formaldehyde removal purifier described in the first aspect or any embodiment of the first aspect.

[0014] According to the fourth aspect, embodiments of the present invention also provide a purification system, including an electrical device with a heating function for air and the formaldehyde removal purifier described in the third aspect.

[0015] Specifically, the electrical equipment is an air conditioner, a fresh air system, or an electric heater.

[0016] The purification system, formaldehyde removal purifier, and control method and device provided in this invention embodiment can automatically turn on the formaldehyde removal purifier when it is in standby mode by acquiring preset operating parameters of the electrical equipment and determining whether the electrical equipment is in heating mode based on the operating parameters. When the electrical equipment is in heating mode, the formaldehyde removal purifier is controlled to enter the operating mode from standby mode, thus realizing the automatic start of the formaldehyde removal purifier.

[0017] This is because, when formaldehyde release is relatively slow, the indoor temperature rises when electrical appliances are in heating mode. Since formaldehyde volatilizes faster with increasing temperature, the increased indoor temperature accelerates formaldehyde release, potentially causing indoor formaldehyde concentrations to exceed standards. The aforementioned technical solution allows the formaldehyde removal purifier to automatically switch from standby to operating mode, accelerating formaldehyde removal. This makes the purifier suitable for application scenarios with slow formaldehyde release. Furthermore, the purifier requires no user intervention to operate, improving the user experience.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0025] This invention provides a control method for a formaldehyde removal purifier, which is applied to the formaldehyde removal purifier. Figure 1 This is a schematic flowchart of the formaldehyde removal and air purification control method in an embodiment of the present invention. Figure 2 This is a flowchart illustrating an example of a formaldehyde removal and air purification control method in an embodiment of the present invention, as shown below. Figure 1 and Figure 2 As shown, the control method of the formaldehyde removal purifier in this embodiment of the invention includes the following steps:

[0026] S101: When the formaldehyde removal purifier is in standby mode, obtain the preset operating parameters of the electrical equipment.

[0027] In this embodiment of the invention, the formaldehyde removal purifier is an air purifier with formaldehyde removal function. It is understood that, in addition to removing formaldehyde, the formaldehyde removal purifier may also have other functions, such as removing particulate matter from the air.

[0028] In this embodiment of the invention, the electrical equipment has a heating function for the air. Specifically, the electrical equipment includes, but is not limited to, air conditioners, fresh air systems, and electric heaters. For example, the air conditioner can be a household air conditioner or a central air conditioning system.

[0029] S102: Determine whether the electrical equipment is in heating mode based on the operating parameters.

[0030] In heating mode, the electrical appliance heats the air. For example, when an air conditioner is used for heating, it is in heating mode; when an electric heater is used, it is in heating mode.

[0031] S103: When the electrical device is in heating mode, control the formaldehyde removal purifier to enter the running state from the standby state.

[0032] This is because, when formaldehyde release is relatively slow, the indoor temperature rises when electrical appliances are in heating mode. Since formaldehyde volatilizes faster with increasing temperature, the increased indoor temperature accelerates formaldehyde release, potentially causing indoor formaldehyde concentrations to exceed standards. The aforementioned technical solution allows the formaldehyde removal purifier to automatically switch from standby to operating mode, accelerating formaldehyde removal. This makes the purifier suitable for application scenarios with slow formaldehyde release. Furthermore, the purifier requires no user intervention to operate, improving the user experience.

[0033] The implementation of this solution includes network-connected electrical appliances such as air conditioners and network-connected formaldehyde-removing air purifiers. An air conditioner is installed in the room, the air purifier is placed inside, and the room contains sources of formaldehyde release, such as furniture.

[0034] In other words, the control method for the formaldehyde removal purifier provided in this embodiment of the invention achieves joint formaldehyde removal by linking with electrical equipment that has the function of heating air, which has the advantages of high efficiency and speed.

[0035] As an optional implementation, before obtaining the preset operating parameters of the electrical appliance, the following steps are also included: determining whether the formaldehyde removal purifier has established a communication connection with the electrical appliance that has an air heating function; when the formaldehyde removal purifier establishes a communication connection with the electrical appliance, the step of obtaining the preset operating parameters of the electrical appliance is executed. In other words, the operating parameters of the electrical appliance are obtained through the communication connection established between the formaldehyde removal purifier and the electrical appliance.

[0036] In this embodiment of the invention, the formaldehyde removal purifier and the electrical device with air heating function can establish a communication connection through any method in the prior art. For example, a communication connection can be established through a three-way handshake based on the TCP / IP protocol.

[0037] As an optional implementation, when the formaldehyde removal purifier has not established a communication connection with the electrical device, it determines whether a running command has been received; when the running command is received, the formaldehyde removal purifier is controlled to enter the running state from the standby state. In other words, even when the formaldehyde removal purifier has not established a communication connection with the electrical device, it can still enter the running state under the user's control upon receiving a user-inputted running command.

[0038] As an optional implementation, when controlling the formaldehyde removal purifier to enter the operating state from the standby state, or after controlling the formaldehyde removal purifier to enter the operating state from the standby state, the method further includes: acquiring the detection data of the formaldehyde removal purifier; and determining the operating parameters of the formaldehyde removal purifier based on the detection data. In other words, the control method for the formaldehyde removal purifier in this embodiment of the invention can not only control the formaldehyde removal purifier to automatically turn on, but also control the operating parameters of the formaldehyde removal purifier.

[0039] Specifically, the detection data from a formaldehyde-removing air purifier can be the concentration of formaldehyde. This air purifier is equipped with a formaldehyde sensor, which can detect the indoor formaldehyde concentration.

[0040] It should be noted that the appliance being in heating mode may or may not cause indoor formaldehyde concentration to exceed the standard. As an optional implementation, after acquiring the detection data from the formaldehyde removal purifier, the system also includes displaying the detection data; the user can determine whether the formaldehyde removal purifier needs to be operated based on the displayed detection data, and can turn it off if it is not needed.

[0041] Specifically, the operating parameters of a formaldehyde-removing air purifier can be understood as parameters that affect the speed at which the purifier removes formaldehyde, such as the purifier's speed setting. For example, after obtaining the detection data from the formaldehyde-removing air purifier, the range to which the detection data belongs can be determined, and the purifier's speed setting can be determined based on this range. For instance, a formaldehyde sensor checks the indoor formaldehyde concentration; when the concentration is between 0.1 and 10 mg / m³... 3 When the concentration is >10mg / m³, the purifier operates in automatic mode to remove formaldehyde normally; when the concentration is >10mg / m³, the purifier will not remove formaldehyde. 3 At that time, the air purifier was running at its highest setting.

[0042] The control method for the formaldehyde removal purifier in this embodiment of the invention can not only control the automatic start-up and operating parameters of the formaldehyde removal purifier, but also control its automatic shutdown. Specifically, after controlling the formaldehyde removal purifier to enter the operating state from the standby state, the method further includes: continuing to acquire the operating parameters of the electrical device; determining whether the electrical device is in a non-heating mode based on the operating parameters; and when the electrical device is in a non-heating mode, controlling the formaldehyde removal purifier to enter either the standby state or the shutdown state. In other words, when the electrical device is in a non-heating mode, the indoor temperature decreases, further slowing down the formaldehyde release rate. At this time, the formaldehyde concentration in the room can remain within the normal range without the formaldehyde removal purifier operating. Using the above technical solution, the automatic shutdown of the formaldehyde removal purifier can be achieved, reducing energy consumption.

[0043] As an optional implementation, before controlling the formaldehyde removal purifier to enter standby mode or turn off mode from the operating state, the method further includes: determining whether the formaldehyde removal purifier is in operating mode; and when the formaldehyde removal purifier is in operating mode, controlling the formaldehyde removal purifier to enter standby mode or turn off mode from the operating state. This is because, in some cases, the user may have already turned off the formaldehyde removal purifier when the appliance is in heating mode for various reasons. For example, at night, the noise from the formaldehyde removal purifier may be too loud and affect the user's sleep, so the user may have already turned it off when the appliance is in heating mode; or, the user may determine that the formaldehyde removal purifier does not need to be turned on for formaldehyde removal based on the formaldehyde concentration displayed on the purifier, and thus turn it off.

[0044] Corresponding to the control method of the formaldehyde removal purifier described above, this embodiment of the invention also provides a control device for the formaldehyde removal purifier. Figure 3 This is a schematic diagram of the structure of the formaldehyde removal and purification device control device according to an embodiment of the present invention, as shown below. Figure 3 As shown, the formaldehyde removal and purification device control unit includes an acquisition module 30, a processing module 31, and a control module 32.

[0045] Specifically, when the formaldehyde removal purifier is in standby mode, the acquisition module 30 is used to acquire preset operating parameters of the electrical equipment;

[0046] Processing module 31 is used to determine whether the electrical equipment is in heating mode based on the operating parameters;

[0047] When the electrical device is in heating mode, the control module 32 is used to control the formaldehyde removal purifier to enter the running state from the standby state.

[0048] Before acquiring the preset operating parameters of the electrical equipment, the acquisition module 30 is also used to: determine whether the formaldehyde removal purifier has established a communication connection with the electrical equipment that has a heating function for air; when the formaldehyde removal purifier establishes a communication connection with the electrical equipment, the step of acquiring the preset operating parameters of the electrical equipment is executed.

[0049] When the formaldehyde removal purifier and the electrical device have not established a communication connection, the acquisition module 30 is also used to determine whether a running command has been received; when the running command is received, the control module 32 is also used to control the formaldehyde removal purifier to enter the running state from the standby state.
