The claimed device for an electric multicooker with Wi-Fi control can be used in light industry in the production of such devices.

State of the art

There are a number of technical solutions aimed at the development of electric multicookers, which could be controlled remotely. In particular, multicooker devices are known that are capable of wireless communication with a remote WI-FI router (modem).

The closest analogue of the claimed utility model is known from patent RU 132324 U1 dated May 24, 2013, an electric multicooker device with Wi-Fi control. This multicooker contains a housing with at least one heating element and a container for cooking located in the housing, while the housing contains a control module, the outputs of which are connected respectively: with the output of the power module intended for connection to the electrical network, at least , one of the specified heating elements; with the output of the display unit; with inputs of at least one temperature sensor and manual control unit, as well as with the first output of the microprocessor, the second output of which is connected to a conversion module configured to wirelessly communicate with a remote WI-FI router.

The known design of the prototype multicooker has a significant drawback, which is the low stability of wireless Wi-Fi communication due to the fact that the multicooker conversion module is not able to analyze interference that affects the operation of wireless Wi-Fi networks. As a result, the known design is due to intermittent or unstable operation of the wireless connection of the multicooker to the Wi-Fi network. This makes remote control difficult, and sometimes, due to the lack of an informational Wi-Fi signal on the receiving device, impossible.

Thus, the objective of this utility model is to create an electric multicooker device with the possibility of remote control from an application using a Wi-Fi network and the function of automatically filtering the received Wi-Fi information signal from interference generated by devices surrounding the electric multicooker to improve Wi-Fi stability. connection and uninterrupted operation of the remote control of the multicooker.

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

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

The set goal, the technical result required and obtained by using the utility model, is achieved by the fact that an electric multicooker with Wi-Fi control, consisting of a body, a cover, a container for products, a control button on the body and a control unit for the operation of the multicooker with a control module, additionally contains a connected with a control module, a converting module configured to receive and transmit, register and filter a Wi-Fi signal against the background of interference detected by the Wi-Fi signal transceiver unit, the input of which is connected to the microprocessor control device, and the output to the analysis and filtering unit, connected to the interference memory unit.

Implementation of the utility model

Multicookers with Wi-Fi control have a number of advantages compared to conventional multicookers. They have more advanced features and capabilities, such as automatic setting of cooking modes, remote control of the multicooker, use of a mobile application to select recipes and change settings, as well as the ability to be compatible with voice assistants.

Thanks to Wi-Fi control, the multicooker will always be ready for use, even if the user is away from home. In addition, the Wi-Fi control of the multicooker makes cooking more accurate and easier, as the user selects a recipe and sets the cooking modes, and the required temperature and cooking time are monitored by the multicooker, the control module 1 of which received the corresponding information signal from the conversion module 14, which registered Wi-Fi information signal from a remote command device.

Also, a multicooker with Wi-Fi control works on the principle of connecting to the Internet, which allows you to control it through a special mobile application installed on a remote command device, such as a computer, smartphone or tablet. To start working with a multicooker, you need to connect it to Wi -Fi networks. The application allows you to select recipes and set cooking modes, as well as control the multicooker remotely without being near it. For example, you can turn on the slow cooker while in the office or on the street, and by the time you get home, dinner will be ready.

Wi-Fi (Wireless Fidelity), also known as a wireless local area network (WLAN), uses radio waves as a signal propagation medium, and the operation of devices and data transmission on the network occurs without the use of cable connections. Wi-Fi uses the IEEE 802.11 standard, which defines the data transfer protocols used in wireless networks.

Devices connected to Wi-Fi communicate through wireless access points (access points), which are usually connected to a wired Internet network. When a device (such as a computer, phone, or tablet) wants to connect to Wi-Fi, it sends a request to the nearest access point. The access point then sends the request to the wired Internet network to access the Internet. After that, the device can start transmitting data over the wireless network using Wi-Fi protocols.

Wireless Wi-Fi networks usually use two frequency bands - 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. But newer versions of Wi-Fi, such as 802.11ac and 802.11ax, can support higher data rates.

Wi-Fi can also work in different modes, which can be configured on the access point. For example, an access point can operate in infrastructure mode, where it serves as a central access point for Wi-Fi devices, or ad hoc mode, where devices can connect to each other directly without using an access point.

In addition, Wi-Fi can be used to transmit voice and video. This is achieved through the use of Quality of Service (QoS) technology, which prioritizes data streams such as voice and video to ensure a smoother data transfer. According to this solution, the multicooker with Wi-Fi control is compatible with voice assistants such as Google Home, Marusya or Alice, which allows you to turn the multicooker on and off, change cooking modes and control its other functions by voice.

Despite all the advantages, there is a big drawback in the implementation of Wi-Fi communication - this is an unstable connection and transmission of the Wi-Fi signal due to the impact of a large amount of various kinds of interference on it. At the same time, Wi-Fi devices are subject to even small interferences that are created by other devices, including those operating in the same frequency range.

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

At the same time, Wi-Fi wireless devices have a limited range. For example, a home router with an 802.11b/g Wi-Fi access point has a range of up to 60 m indoors and up to 400 m outdoors.

Indoors, the range of a wireless access point may be limited to a few tens of meters depending on the configuration of the rooms, the presence of solid walls and their number, and other obstacles. In turn, obstacles such as walls, ceilings, furniture, metal doors, etc. located between Wi-Fi devices can partially or significantly reflect/absorb radio signals, resulting in partial or complete signal loss. Indoors, mirrors and tinted windows can also cause radio interference. Even the human body attenuates the signal by about 3 dB. At the same time, the presence of solid 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 operation of the conversion module of any Wi-Fi device, including an electric multicooker.

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

In addition, the operation of the Wi-Fi device and the deterioration of the quality of the Wi-Fi connection are also affected by various household appliances operating in the coverage area of the Wi-Fi network. For example, microwave ovens weaken the Wi-Fi signal strength, as they usually also operate in the 2.4 GHz band. In addition, baby monitors are also devices operating in the 2.4 GHz band, which creates interference and degrades the quality of Wi-Fi communications. Wi-Fi connectivity is also affected by CRT monitors, electric motors, wireless speakers operating at 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 the Wi-Fi network.

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

However, in the proposed solution, it was decided to use filtering based on data about these interferences. 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, electromagnetic interference 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 interferer. Interference patterns can be displayed on an interference map that can illustrate the spatial relationships of interference patterns, interference sources, objects that do not emit radio waves, combinations thereof, and the like. , a cordless phone, to determine how it might affect the Wi-Fi transceiver installed on the device, such as an electric multicooker.

Thus, an electric multicooker with Wi-Fi control is proposed, the design of which is designed to form and save an interference pattern from each interference source in order to compare the interference pattern and remove all interference from interference sources and leave only the signal pattern corresponding to the Wi- fi.

It should 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 an interference signature for each interferer. Meanwhile, information about the interferer can be included in the interference signature, such as operating frequency, signal strength, location, user information, and so on, to identify the interferer. To determine which interferer caused the interference pattern to change, the stored interference signatures can be compared with the interference data collected/acquired and the generated interference patterns.

When interference reduces the signal transmission rate, for example, the power level 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 signal-to-interference (noise).

In addition, it is possible to 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 multicooker converting module is based on the use of a Wi-Fi receiver configured as a transceiver unit 15. At the same time, the transceiver unit 15 is configured to receive (for example, collect, collect and measure) signals from interference sources, of which the computational the device of the microprocessor 10 of the converting module 14 can determine data on interference when changing signals by comparing the received signals with the existing base of reference signals stored in the memory unit 13. This comparative analysis is carried out in the analysis and filtering unit 12 of the microprocessor 10. In this case, the receiver Wi- Fi implemented as 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 TV, and cable TV can be configured to perform spectral analysis to measure the energy content, including signal carrier, signal harmonics, and/or signal intermodulation. Changes in the energy content can indicate interference and can be used to determine the source of the interference. For example, when the energy content is measured over time, spectrum analysis can indicate to the receiver whether the interferer is a frequency modulated signal or if it is a frequency hopping signal. For example, some types of signals, 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 Communication (DECT) and Code Division Multiple Access (CDMA) may have well-defined bandwidth.

Also, the conversion module 14 performs an analysis of the energy content in the time domain and can determine the pulse repetition frequency (PRF) of the interferer. 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, if microwave oven signals are compared with the 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 if the interferer is a microwave or a GSM cellular transmitter.

Thus, the conversion module 14, 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 signal strength present in a particular location.

At the same time, at the stage of forming an interference pattern, it can be created and/or generated based on the received interference data. For example, an interference pattern may include one or more of the following: radio interference pattern, microwave interference pattern, combinations thereof, 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 block 13 and is subsequently used as reference signals of the computing device of the microprocessor 10.

As shown in the block diagram in FIG. 1, the multicooker device includes a control module 1 connected to a power supply and communication unit 2, to which the supply voltage is supplied from the mains (in Fig. 1, the supply voltage is shown by a bold arrow). The power and switching unit 2 performs two tasks at once: it converts the 220 V alternating voltage supplied from the network into a 5 V direct current voltage to power the control module 1 and 12 V to power the switching circuit, which provides the supply voltage according to the signal from the control and switching unit 2 220 V to heating elements 3, 4 and 5.

The control module 1 contains a microcontroller (not shown in the drawings) and is connected to the display unit 6, manual control unit 7, which includes buttons for controlling the multicooker operation mode, and can also be connected to LEDs to illuminate the menu on the display unit 6.

The control module 1 is also connected to two thermal resistances - the main temperature sensor 9 and the top temperature sensor 8, which provide automatic adjustment and maintenance of the set temperature in the multicooker.

In accordance with the proposed solution, the control module 1 is connected in series via feedback with the microprocessor 10, namely, with the control device 11 of the microprocessor 10, which in turn is connected to the transceiver unit 15. The microprocessor 10 also includes an analysis and filter unit 12, the first the 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 13. At the same time, the microprocessor 10 with the built-in control device 11 and the computing analysis and filtering unit 12, together with the interference memory unit 13 and the receiving unit gears 15 form the converting module of the multicooker 14.

The specified conversion module 14 performs the main function is the reception, filtering, amplification and transmission to the microcontroller of the control module 1 information Wi-Fi signal. At the same time, the proposed constructive implementation of the converting module 14 provides filtering of all received interference signals due to the formation of an interference pattern, which may contain one or more of the following elements: a radio interference pattern, a 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 block 13 and is subsequently used as reference signals of the computing device of the microprocessor 10, such as the analysis and filtering unit 12.

Thus, the information transmitted by the user via a Wi-Fi signal to the multicooker will always be executed by the multicooker 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 multicooker device is carried out as follows.

During the initial installation of an electric multicooker 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 multicooker case, or the LCD screen of the multicooker, or by turning the corresponding relay on the multicooker case ( these elements are widely known and therefore not shown in the figures), which activates the manual control unit 7 to transmit a signal to the control module 1 and further transfer the command to the transceiver unit 15 through the control device 11 of the microprocessor 10. After scanning, the analysis of signals from all existing around the multicooker of interference sources using the analysis and filtering unit 12 with the recording of the obtained data on interference patterns in the memory of the interference memory unit 13. This step will ensure more efficient operation of the conversion module 14. Obviously, in a large office space or at a manufacturing plant in which the Wi-Fi signal can easily pass tens of meters in a small kitchen filled with various kinds of appliances, including a refrigerator, microwave oven, etc., where the Wi-Fi signal will be reflected from surfaces, absorbed and affected by electromagnetic radiation signals from working devices , the interference pattern of interference will differ significantly.

The received interference signals are recorded in the interference memory 13 as additional reference interference signals. Thus, in the interference memory block 13 of the converting module 14, an additional database is formed about the received interference patterns of signals from a variety of interference sources actually located around the multicooker device and affecting the efficiency of receiving and/or transmitting a Wi-Fi signal. At the same time, the interference memory block 13 contains stored data of reference signals of interference patterns of interference signals from documented sources of interference, for example, signal types such as Bluetooth (802.15.1) and Zigbee (802.15.4), which use frequency hopping or extension methods. spectrum that can be easily detected. That is, additional data is stored in the interference memory block 13 - this is data on the interference patterns of interference generated from interference sources around the multicooker. Thus, when analyzing the signal in the analysis and filtering unit 12, their classification will be greatly simplified by comparing with the signals available in the memory unit 13 of all the reference signals of the interference patterns of the signals present in it.

As a result, from the analysis and filtering unit 12 to the control device 11 of the microprocessor 10, an information control Wi-Fi signal is received, which is then transmitted to the control module 1 of the multicooker.

In addition, the multicooker device can give feedback to the user through the conversion module 14, for example, about the presence / absence of a finished dish in the multicooker, about the temperature of the dish, about the need to heat the dish, about the end time for cooking dinner, etc. In this case, the data from of the control module 1 fall on the control device 11 of the microprocessor 10, then transferred to the transceiver unit 15, which emits an information signal to the remote user device.

Let's take a specific example.

The signal carrying information about the temperature request of the finished dish (the user generates a remote request for the temperature of the finished dish, which is in the keep warm mode in the multicooker at a given time), comes from any of the devices that support the transmission and reception of a Wi-Fi signal to the router , for example, a Wi-Fi router (modem), where it is processed and then received by the converting module 14 of the multicooker. The transceiver unit 15 of the converting module 14 transmits the entire spectrum of signals received from the surrounding space to the microprocessor 10 in the analysis and filtering unit 12, then, at the request of the analysis and filtering unit 12, information about the interference pattern of the reference interference is transmitted from the memory of the interference memory unit 13. The analysis and filtering unit 12 operates by means of the control shown in FIG. 2 algorithms. In particular, the initially received signal is analyzed in order to detect the presence of a “new” signal that is not in the database of the interference memory block 13. In the case of a positive decision about the presence of a “new” interference signal, the analysis and filtering block 12 transmits information about the interference pattern new interference to the interference memory 13 and there this signal is stored as an additional reference signal. If the received signal is available in the saved database of reference signals, the received signal is compared with the signals from the interference memory block 13. Next, it is analyzed whether there is an information Wi-Fi signal we need among the signals, filtering is carried out and all interference signals are removed, and then only the Wi-Fi information signal is transmitted.

The converted signal comes from the control device 11 of the microprocessor 10 to the control module 1. The control module 1 connects to the main temperature sensor 9 and converts the temperature value into an electrical signal, which is transmitted from the control module 1 through the control device 11 of the microprocessor 10 to the transceiver unit 15 and further to the router, and then to one of the above user command devices.

In turn, the user, having received information about the temperature of the dish, forms a task to heat dinner in a slow cooker to a temperature of 75°C. The temperature of the dish is set by the user remotely using any device that supports a Wi-Fi connection, for example, a computer, or a tablet, or a mobile phone, etc. The signal carrying information about the temperature of the dish at 75 ° C, set by the user, comes from of these devices to the router, Wi-Fi router (modem), where it is processed and then received by the converting module 14. The transceiver unit 15 of the converting module 14 transmits the entire spectrum of signals received from the surrounding space to the microprocessor 10 to the analysis and filtering unit 12, then at the request of the analysis and filtering unit 12, information about the interference pattern of the reference interference is transmitted from the memory of the interference memory unit 13. The analysis and filtering unit 12 performs actions by means of the algorithm disclosed in FIG. 2.

The converted information signal comes from the control device 11 of the microprocessor 10 to the control module 1. The control module 1 connects the heating element of the multicooker 3, 4, 5, depending on the mode and conditions, to the electrical network through the power supply and communication 2. The temperature of the dish in the multicooker is controlled by thermal sensors 8 and 9. After heating the main temperature sensor 9 to the required temperature, the voltage supply to the heating element stops until the temperature in the upper zone of the working container of the multicooker reaches a certain value, which is determined by the upper temperature sensor 8. Then the heating is turned on again and after a while again turns off. The frequency, mode of operation (simultaneous switching on or alternate switching on) and the duration of switching on the heating elements 3, 4, 5 depend on the selected operating mode of the multicooker (cooking, frying, stewing, porridge, pilaf, baking, etc.). Next, the temperature value converted into an electrical signal is sent to the control module 1, which compares the obtained temperature value with the temperature set by a remote control device (for example, such as a computer, tablet, mobile phone). As the temperature of the dish reaches 75°C, that is, the desired temperature, it sends a signal to the power supply and communication unit 2 and disconnects the heating elements 3, 4, 5 from the electrical network. In this case, the information signal about reaching the set temperature of 75°C from the control module 1 through the microprocessor 10, it is the control device 11, enters the transceiver unit 15 and then is transmitted to the router, and then to one of the above user command devices.

Thus, the user receives information both about the initial temperature of the finished dish in the multicooker, and about heating the dish to a temperature corresponding to the value set by him. In this case, the command from the remote user device will be executed even if the Wi-Fi signal is weakened, 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 multicooker, for example, in another room) and noise arising from the operation of various kinds of devices (smart TV, microwave ovens, game consoles, refrigerator, etc.).

As follows from all of the above, due to the signal processing in the conversion module 14, the quality of the Wi-Fi connection is improved, which in turn improves the stability of the connection of the multicooker to the Wi-Fi wireless network for remote control of its operating modes.

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

Reception and transmission of data between a portable device with an installed application and a device that receives commands (a transceiver unit in the multicooker case) is carried out using such a type of communication / connection as Wi-Fi.

Thus, the proposed electric multicooker with Wi-Fi control, which includes the above elements, provides remote control from the application using a Wi-Fi network due to the effective function of automatically filtering the received information Wi-Fi signal from interference generated by devices and obstacles surrounding the electrical multicooker, which increases the stability of the Wi-Fi connection and the smooth operation of the remote control of the multicooker.

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