Description

The utility model relates to the field of air purification, in particular to a household air humidifier, the operation of which can be controlled either manually or remotely using a Wi-Fi connection. The claimed humidifier device with Wi-Fi control can be used in light industry in the production of such devices.

State of the art

An air humidifier is an electrical device that increases the humidity of the air and is widely used in household, medical and industrial production. It can effectively increase air humidity, purify the air, and improve the living conditions of the human body, especially for the symptoms of asthma, colds, skin allergies and other aids.

It is known that air always contains water vapor, its percentage depends on the ambient temperature. In this case, air humidity is determined by the amount of water vapor contained in the air. This is an important parameter for comfort and health. Humidity is measured using a hygrometer (humidity sensor). Typically, a comfortable humidity range for residential areas is approximately 30-60%. Low humidity can cause dry skin and respiratory irritation, while high humidity can promote mold growth and alleviate heat stress.

In turn, the optimal level of indoor humidity depends on many factors, including climatic conditions and individual preferences.

Thus, too low humidity, especially in the winter months, can cause breathing problems, dry skin, irritation of the eyes and mucous membranes. Electronic devices and furniture can also be damaged by dry air. On the other hand, too much humidity can encourage mold, make it easier for bacteria to spread, and affect the durability of some materials.

Using a humidifier during dry periods with a moisture sensor in the air can help maintain comfortable indoor conditions.

Humidifiers usually work independently. Users can only manually install and operate humidifiers using touch controls.

At the same time, a number of technical solutions are known aimed at developing air humidifiers that could be controlled remotely. In particular, humidifier devices are known that are capable of wireless communication with a remote WI-FI router (modem).

Thus, the design of a humidifier is known, disclosed in patent CN 205505311 U, published on August 24, 2016, selected as a prototype. The known humidifier contains a housing, a filter, a motor and a fan installed inside the housing. The housing is equipped with air inlet and outlet, a temperature sensor and a humidity sensor. Also in the humidifier body there is a WI-FI module, a microcontroller, and a memory unit. According to the known device, the humidifier is remotely controlled, and the humidity level of the room is determined.

The known design of the prototype humidifier has a significant drawback, which is the low stability of wireless Wi-Fi communication due to the fact that the converting module of the humidifier is not capable of analyzing interference that affects the operation of wireless Wi-Fi networks. As a result, the known design is subject to intermittent or unstable operation of the humidifier's wireless connection to the Wi-Fi network. This makes remote control difficult and sometimes, due to the lack of Wi-Fi connection, impossible.

Thus, the objective of this useful model is to create a humidifier device with the ability to remotely control from an application using a Wi-Fi network and the function of automatically filtering the received Wi-Fi information signal from interference created by devices surrounding the humidifier, to increase the stability of the Wi-Fi connection and uninterrupted operation of remote control of its operation.

The technical result of the claimed utility model is to increase the stability of the connection of the humidifier to the Wi-Fi wireless network for remote control of its operating modes while maintaining the high efficiency of the humidifier device as a whole and the operation of the Wi-Fi signal transceiver system built into the humidifier, in particular.

Disclosure of utility model

Just as in the closest analogue, the proposed humidifier contains a housing with a heating element, a filter, a fan, a control unit for the operation of the humidifier, made with the ability to connect the leads to the above-mentioned heating element and the electrical network. In turn, the humidifier operation control unit includes a control module with a controller, a temperature sensor, an air humidity sensor and a manual humidifier control unit. Also in the humidifier body there is a converting module connected to the control module, which is designed for wireless communication with a remote WI-FI router (modem).

The difference between the claimed humidifier device and its analogue is that the humidifier converting module is designed to receive, register and filter a Wi-Fi signal against the background of interference recorded by the transceiver unit.

The set goal, the technical result required and obtained when using the utility model, is achieved by the fact that the humidifier with Wi-Fi control consists of a housing, a lid, a water tank, a filter element, a control panel on the housing and a control unit for the operation of the humidifier with a control module built into the housing , and additionally contains a WiFi conversion module connected to the control module, configured to receive, register and filter a Wi-Fi signal against the background of interference recorded by a Wi-Fi signal transceiver unit, the input of which is connected to the microprocessor control device, and the output is connected to the analysis and analysis unit. filtering connected to the interference memory unit.

Implementation of a utility model

As is known, in wireless networks, in particular in Wi-Fi networks, radio waves are used as a signal propagation medium, and the operation of devices and data transmission on the network occurs without the use of cable connections. In this regard, the operation of wireless networks is affected by a greater amount of various types of interference. In turn, Wi-Fi devices are susceptible to even slight interference that is created by other devices, including those operating in the same frequency range.

As you know, wireless Wi-Fi networks use two frequency ranges - 2.4 and 5 GHz. 802.11b/g wireless networks operate in the 2.4 GHz band, 802.11a networks operate in the 5 GHz band, and 802.11n networks can operate in both the 2.4 GHz and 5 GHz bands.

Bluetooth devices and wireless keyboards and mice also operate in the 2.4 GHz frequency range and, therefore, may affect the operation of the access point and other Wi-Fi devices.

However, Wi-Fi wireless devices have a limited range. For example, a home Internet center with a Wi-Fi access point standard 802.11 b/g has a range of up to 60 m indoors and up to 400 m outdoors.

Indoors, the range of a wireless access point can be limited to several tens of meters depending on the configuration of the rooms, the presence of solid walls and their number, as well as other obstacles.

At the same time, obstacles such as walls, ceilings, furniture, metal doors, etc., located between Wi-Fi devices, can partially or significantly reflect/absorb radio signals, which leads to partial or complete loss of the signal. Moreover, the presence of permanent walls, including concrete and reinforcement, sheet metal, plaster on the walls, steel frames, etc. also affects the quality of the radio signal and can significantly impair the performance of the conversion module of any Wi-Fi device, including a humidifier.

Indoors, mirrors and tinted windows can also cause radio signal interference. Even the human body attenuates the signal by about 3 dB.

Table 1 shows the loss of efficiency of a Wi-Fi signal when passing through various obstacles that are present in indoor environments. The data is given for a network operating in the 2.4 GHz frequency range.

In addition, the operation of the Wi-Fi device and the deterioration of the quality of Wi-Fi communication are also affected by various household appliances operating within the coverage area of the Wi-Fi network.

For example, microwave ovens weaken Wi-Fi signal strength because they typically also operate in the 2.4 GHz band. In addition, baby monitors are devices that also operate in the 2.4 GHz band, which creates interference and degrades the quality of Wi-Fi communications. Also, the quality of communication over a Wi-Fi network is affected by cathode ray tube monitors, electric motors, wireless speakers operating at a frequency of 2.4 or 5 GHz, some sources of electrical voltage, such as electrical wiring, cables with insufficient shielding, and coaxial cables and connectors used with some types of satellite dishes, external monitors and LCD screens operating at 2.4 GHz, wireless cameras, and other Wi-Fi devices within range of a Wi-Fi network.

Thus, various devices can interfere with the registration and transmission of signals over a Wi-Fi network. As discussed above, these devices may include communications and/or electronic devices, including both wired and wireless devices (for example, microwave ovens, printers, computers, tablets, phones, cordless phones, network nodes, network devices, set-top boxes, televisions, radios, communication devices), terminals, power lines, transmitters, various communication protocols used by devices and the like.

At the same time, in the proposed solution it was decided to use filtering based on data about this interference. It is proposed to use these interferences to create and/or generate interference patterns for each interference source.

Common types of interference can be divided into mutual or co-channel interference CCI (co-channel interference), inter-carrier interference ICI (inter-carrier interference) due to signal modulation, EMI (electromagnetic interference) due to radiation from an external source . In turn, the interference data can be used to create and/or generate interference patterns for each interference source. The interference patterns may be displayed on an interference map, which may illustrate the spatial relationships of interference patterns, interference sources, non-radio emitting objects, combinations thereof, and the like. The generated interference map can be used to evaluate an unknown and/or new interference source, such as a cordless phone, to determine how it might affect a Wi-Fi transceiver installed on a device, such as a humidifier, for example.

Thus, a Wi-Fi controlled humidifier is proposed, the design of which is designed to form and store the interference pattern from each interference source in order to compare the interference pattern and remove all interference from the interference sources and leave only the signal pattern corresponding to the Wi-Fi signal. Fi.

It must be reiterated that each interferer has its own unique interference pattern, and it is this data that can be used to create and/or generate a signature for each interferer. In this case, information about the interference source may be included in the interference signature, such as operating frequency, signal power level, location, user information, and so on, to identify the interference source. To determine which interference source caused the interference pattern to change, the stored interference signatures can be compared to the interference data collected/obtained and the generated interference patterns.

When interference reduces the signal transmission rate, the power level, for example, can be coordinated. You can also change the signal modulation to improve the signal-to-noise ratio between the desired Wi-Fi signal and the interfering signal (noise).

In addition, you can determine the network address of the interference source from the interference signature. For example, the network address may include an Internet Protocol address, a network address, a media access control (MAC) address, an Internet address, and/or the like.

The implementation of the humidifier converting module is based on the use of a Wi-Fi receiver configured as a transceiver unit 15. In this case, the transceiver unit 15 is configured to receive (for example, collect, collect and measure) signals from interference sources, from which the computing device of the microprocessor 10 converts module 11 can determine data on interference when signals change by comparing the received signals with the existing base of reference signals stored in the memory unit 14. This comparative analysis is carried out in the analysis and filtering unit 13 of the microprocessor 10. In this case, the Wi-Fi receiver, made in form of a transceiver unit 15, may have a plurality of receiver channels that are capable of measuring the relative direction of the signal with the highest transmission energy. For example, a wideband or full spectrum receiver in a cable modem, satellite television, and cable television may be configured to perform spectral analysis to measure energy content, including signal carrier, signal harmonics, and/or signal intermodulation. Changes in energy content can indicate interference and can be used to determine the source of the interference. For example, when energy content is measured over time, spectral analysis can indicate to the receiver whether the interfering source is a frequency-modulated signal or a frequency-hopping signal. For example, some signal types, such as Bluetooth (802.15.1) and Zigbee (802.15.4), use frequency hopping or spread spectrum techniques that can be easily detected. In another example, wireless and cellular technologies such as digital enhanced wireless communications (DECT) and code division multiple access (CDMA) may have a well-defined bandwidth.

Also, the conversion module 11 performs time domain energy content analysis and can determine the pulse repetition frequency (PRF) of the interference source. Time domain energy content analysis to determine PRF can be used in situations where signal analysis results in more than one type of interferer. In one aspect, instead of signal analysis, time domain analysis can be used to determine the PRF of the interferer.

As an example of using PRF to determine the source of interference, consider microwave ovens. Microwave ovens transmit either a continuous wave or long signal cycles lasting several seconds or more. However, when comparing the signals of microwave ovens with global system for mobile cellular transmitters (GSM), the latter have a relatively higher PRF compared to microwave ovens (approximately 216 Hz with an 8 Hz component). Based on the PRF, the computing device can determine whether the source of interference is a microwave or a GSM cellular transmitter.

Thus, the converter module of the humidifier 11, due to its design, can determine sources of interference, including sources that have documented characteristics (reference interference), can determine the type of radio frequency interference and the signal strength present in a certain location.

Moreover, at the stage of forming the interference pattern, it can be created and/or generated based on the received interference data. For example, an interference pattern may contain one or more of the following elements: radio interference pattern, microwave

interference pattern, their combinations, and the like. In addition, the interference pattern may contain a frequency spectrum associated with multiple interference sources. The interference pattern is stored in the interference memory unit 14 and is subsequently used as reference signals of the microprocessor computing device 10.

As shown in the block diagram in FIG. 1, the humidifier device includes a control module for the humidifier 1 with a controller (not shown in the drawings), one output of which is designed to be connected to the power supply 5. The power supply 5 can have either an external constant power supply from the electrical network or can be of a battery type. Also, the control module 1 is connected to the air temperature sensor 2, the air humidity sensor 3, the internal temperature sensor 4, the display unit 6, the internal heating element 7, the ionizer unit 8 and the water level sensor 9. These blocks are included in the manual control unit of the humidifier, shown in Fig. . 1 dotted line.

In accordance with the proposed solution, the control module with controller 1 is connected in series via feedback to the microprocessor of the humidifier 10, namely with the control device 12 of the microprocessor 10. In turn, the microprocessor of the humidifier 10, namely the control device 12, is connected to the transceiver unit 15. Microprocessor 10 also includes an analysis and filtering unit 13, the first input of which is connected to the output of the transceiver unit 15, and the second input is connected by feedback to the interference memory unit 14. In this case, the microprocessor of the humidifier 10 with a built-in control device 12 and the analysis and filtering computing unit 13, together with the interference memory unit 14 and the transceiver unit 15 form the Wi-Fi conversion module 11 of the humidifier.

The specified converting module of the humidifier 11 performs the main function - it is receiving, filtering, amplifying and transmitting an information Wi-Fi signal to the controller of the control module 1. In this case, the proposed design implementation of the converting module of the humidifier 11 ensures filtering of all received interference signals through the formation of an interference pattern, which may contain one or more of the following elements: radio interference pattern, microwave interference pattern and combinations thereof. In addition, the interference pattern may contain a frequency spectrum associated with multiple interference sources. The interference pattern is stored in the interference memory unit 14 and is subsequently used as reference signals of the computing device of the microprocessor 10, such as the analysis and filtering unit 13.

Thus, the information transmitted by the user via a Wi-Fi signal to the humidifier will always be carried out by the humidifier device, regardless of how much the specified Wi-Fi information signal is affected by interference from external devices and/or obstacles.

The operation of the claimed humidifier device is carried out as follows.

During the initial installation of a humidifier with Wi-Fi control, the area is scanned by turning on the transceiver unit 15. This activation can be done manually by pressing the corresponding button on the humidifier body, or the LCD screen of the humidifier, or by turning the corresponding relay on the humidifier body (these elements are widely known and therefore not shown in the figures), which activates the manual control unit of the humidifier to transmit a signal to the controller of the control module 1 of the humidifier and further transmit the command to the transceiver unit 15 through the control device 12 of the microprocessor 10. After scanning, signals from all sources existing around the humidifier are analyzed interference using the analysis and filtering unit 13 with recording of the received data on interference patterns into the memory of the interference memory unit 14. This step will ensure more efficient operation of the converting module 11 of the humidifier. Obviously, in a large office space, in which the Wi-Fi signal can easily travel tens of meters, and in an apartment filled with various types of appliances, including a refrigerator, TV, etc., where the Wi-Fi signal will be reflected from surfaces, absorbed and exposed to electromagnetic radiation from signals from operating devices, the interference pattern will vary significantly.

The received interference signals are recorded in the interference memory unit 14 as additional reference interference signals. Thus, in the interference memory unit 14 of the Wi-Fi converting module 11, an additional database is formed about the received interference patterns of signals from multiple sources of interference actually located around the humidifier device and affecting the efficiency of Wi-Fi signal reception. In this case, the interference memory unit 14 contains stored reference signal data of interference patterns of interference signals from documented interference sources, for example, signal types such as Bluetooth (802.15.1) and Zigbee (802.15.4), which use frequency hopping or spreading methods spectrum that can be easily detected. That is, additional data is stored in the interference memory unit 14 - this is data on the interference patterns of interference generated from interference sources around the humidifier. Thus, when analyzing a signal in the analysis and filtering unit 13, their classification will be significantly simplified due to comparison with the signals available in the memory unit 14 of all the reference signals of the interference patterns of the signals contained in it.

As a result, an information control Wi-Fi signal is received from the analysis and filtering unit 13 to the control device 12 of the microprocessor 10, which is then transmitted to the controller of the control module 1 of the humidifier.

In addition, the humidifier device can give feedback to the user through the Wi-Fi 11 conversion module, for example, about the presence/absence of water in the humidifier, about the water temperature when the humidifier is operating in the “warm steam” mode, about the humidity level in the room, about the room temperature , about the temperature of the internal elements of the humidifier for its correct operation, turning on/off the built-in ionizer to saturate the air with negative ions, etc. In this case, data from the controller of the control module 1 reaches the control device 12 of the microprocessor 10, and is then transmitted to the transceiver unit 15, which emits an information signal to a remote user device.

Let's look at a specific example.

A signal carrying information about a request for the level of humidity in the room (the user creates a remote request about the current humidity in the room) comes from any of the devices that support the transmission and reception of a Wi-Fi signal to a Wi-Fi router (modem), where it is further processed is received by the Wi-Fi conversion module 11 of the humidifier. The transceiver unit 15 of the Wi-Fi converter module 11 transmits the entire spectrum of signals received from the surrounding space to the microprocessor 10 in the analysis and filtering unit 13, then, at the request of the analysis and filtering unit 13, information about the interference pattern of reference interference is transmitted from the memory of the interference memory unit 14 . The analysis and filtering unit 13 carries out actions through the one disclosed in FIG. 2 algorithms. In particular, the initially received signal is analyzed in order to identify the presence of a “new” signal that is not in the database of the interference memory unit 14. In the case of a positive decision about the presence of a “new” interference signal, the analysis and filtering unit 13 transmits information about the interference pattern new interference into the interference memory block 14 and there this signal is stored as an additional reference signal. If the received signal is in the saved database of reference signals, the received signal is compared with signals from interference memory block 14. Next, it is analyzed whether the Wi-Fi information signal we need is among the signals, filtering is carried out and all interference signals are deleted, and then only the Wi-Fi information signal is transmitted.

The converted signal comes from the control device 12 of the microprocessor 10 to the controller of the control module 1 of the humidifier. The control module 1 connects to the humidity sensor 3 of the humidifier and converts the humidity level in the room into an electrical signal, which is transmitted from the controller of the control module 1 of the humidifier through the control device 12 of the microprocessor 10 to the transceiver unit 15 and then to the Wi-Fi router, and then to one of the above-mentioned user command devices.

In turn, the user, having received information about the humidity level in the room, creates a task to increase the humidity level to 50%. The humidity level is set by the user remotely using any device that supports a Wi-Fi connection, for example, a computer, or tablet, or mobile phone, etc. A signal carrying information about the humidity level of 50%, set by the user, is sent from any of the specified devices to the Wi-Fi router (modem), where it is processed and then received by the Wi-Fi 11 converter module of the humidifier. The transceiver unit 15 of the converting module 11 transmits the entire spectrum of signals received from the surrounding space to the microprocessor 10 to the analysis and filtering unit 13, then, at the request of the analysis and filtering unit 13, information about the interference pattern of the reference interference is transmitted from the memory of the interference memory unit 14. The analysis and filtering unit 13 carries out actions through the one disclosed in FIG. 2 algorithms.

The converted signal comes from the control device 12 of the microprocessor 10 to the controller of the control module 1 of the humidifier. The control module 1 connects the humidifier to the electrical network via the power supply 5 or by activating the battery of the power supply 5. The humidity level is carried out by monitoring the set humidity level in the room using a humidity level sensor 3, for example an external hygrometer. In this case, the signal about the humidity level is sent to the controller of control module 1, which compares the humidity level with the level set by a remote command device (for example, such as a computer, tablet, mobile phone) and when the humidity level reaches 50%, disconnects the humidifier from the electrical networks. In this case, the information signal about the achievement of a given level of humidity in the room from the controller of the control module 1 through the microprocessor 10, namely the control device 12, enters the transceiver unit 15 and is then transmitted to the Wi-Fi router, and then to one of the above-mentioned user command devices.

Thus, the user receives information both about the initial humidity level in the room and about the humidity level corresponding to the specified value. In this case, the command from the user’s device will be executed even if the Wi-Fi signal weakens, since the proposed solution will provide a stable Wi-Fi connection regardless of the location of the Wi-Fi router (far from the location of the humidifier, for example, in another room) and noise problems that arise during the operation of various types of devices (smart TV, microwave ovens, game consoles, refrigerators, etc.).

As follows from all of the above, due to signal processing in the Wi-Fi 11 converting module, the quality of Wi-Fi communication is improved, which in turn increases the stability of the humidifier’s connection to the Wi-Fi wireless network for remote control of its operating modes.

The IQ HOME application can be used as a remote control application.

Reception and transmission of data between a portable device with an installed application and the device receiving commands (receiver unit in the humidifier body) is carried out using a type of communication/connection such as Wi-Fi.

Thus, the proposed humidifier with Wi-Fi control, including the elements listed above, provides remote control from the application using a Wi-Fi network due to the effective function of automatically filtering the received Wi-Fi information signal from interference created by devices and obstacles surrounding the humidifier, which increases the stability of the Wi-Fi connection and uninterrupted operation of remote control of the humidifier.

It is obvious that the principle of operation of the humidifier can be any, including:

1) Ultrasonic (the membrane breaks water into dust, which is then blown by a fan);

2) Steam: steam is obtained by heating water and then blowing it out with a fan;

3) Natural: vertically located and partially submerged disks with special water-holding elements, rotating, lift water from the container, which then evaporates from them naturally.

It is mainly necessary to realize the purpose of the humidifier, namely forced humidification of the air in the room to create comfortable living conditions and for therapeutic purposes.

In turn, the following main functions of the claimed device are realized via Wi-Fi:

1) setting target humidity;

2) adjusting the intensity of steam supply;

3) inclusion of additional modes: ionization/night mode/children’s mode/breathing exercise mode; control of backlight, sound commands, locking buttons from accidental pressing ("child lock");

4) setting a schedule for turning on and off on specified days of the week and time in specified operating modes;

5) remotely informing the user: there is not enough water or the water needs to be replaced, about the need for maintenance (cleaning the tank, replacing filters, etc.), about reaching the specified humidity parameters;

6) the ability for the user to create personal modes that best suit his requirements.

As follows from the description of possible implementations of the claimed utility model, the proposed humidifier with remote control functions ensures the achievement of the stated technical result, which consists in increasing the stability of the connection of the humidifier to the Wi-Fi wireless network for remote control of its operating modes while maintaining high efficiency of the humidifier device as a whole and the operation of the Wi-Fi signal transceiver unit built into the humidifier, in particular.

Taking into account the novelty of the set of essential features, the technical solution of the problem, the materiality of all general and specific features of the utility model, proven in the section “State of the art” and “Disclosure of the utility model”; the technical feasibility and industrial applicability of the proposed device, proven in the section “Implementation and industrial implementation of the utility model”; solving the assigned problems and confidently achieving the required technical result when implementing and using a utility model, in our opinion, the declared device satisfies all the requirements for patentability for utility models.

The analysis also shows that all the general and specific features of a utility model are essential, since each of them is necessary, and all together they are not only sufficient to achieve the goal of the utility model, but also allow its implementation in an industrial way.
