Description

Technical field

The invention relates to small household appliances for the kitchen, more specifically to a hand-held electric kitchen tool, namely to an immersion hand blender controlled by a wireless data transfer protocol.

At present, there is a need to improve safety and reliability, as well as to simplify the use of hand-held electric kitchen tools, especially those having exposed rotating parts.

State of the art

In the prior art, a large number of hand-held immersion blenders having various design features are known.

Thus, a hand-held immersion blender is known according to patent document US 7866879 B2, 01/11/2011, having an elastic spatula ring attached to the blade guard as its continuation. The spatula ring is made of a resilient material and is flexible enough to conform to the contours of the interior surface of the mixing container. The prior art blender arrangement thus enables efficient use of an immersion blender, for example when using a mixing vessel made of glass. However, the disadvantage of the known device of the blender is its low reliability and safety, since not only is there no control of the state of the blender (its position in space, rotation speed, pulsation), but also there is no possibility of reducing its speed or turning it off when an unforeseen situation arises (splashing of the mixing product , damage to glass containers for mixing, etc.).

Also known is a hand blender comprising a counter-torque mechanism positioned to counter torque applied to the kitchen appliance by moving parts of the kitchen appliance, such as a motor for driving the tool of the appliance, for example by rotating in opposite directions relative to the motor disclosed in a patent document. EP 3381341 A1, 03.10.2018. This can reduce the forces acting on the hand of the user and thereby improve the safety and ease of use of such a blender by the user by reducing the gyroscopic force and the acceleration/deceleration forces acting on the user's hand of the hand tool, which are eliminated or reduced by counter-rotating rotors. . However, the disadvantage of the known device of the blender is also the inability to control both the state of the blender, including control of its position in space, rotation speed, pulsation, etc., and the inability to reduce its speed or turn it off when an unforeseen situation arises (splashing of the mixing product , damage to the mixing container, stop the blender in case of an unforeseen situation, etc.). This reduces its reliability and safety.

Task and technical result

The object of the present invention is to provide a wirelessly controlled hand-held immersion blender that is highly reliable and safe to use. The technical result of the claimed invention is to increase safety and reliability, as well as to simplify the use of a hand-held immersion blender controlled by a wireless data transfer protocol.

The essence of the invention

The problem is solved, and the required technical result when using the invention is achieved by the fact that the submersible hand blender controlled by a wireless data transfer protocol contains a housing, replaceable nozzles, buttons on the housing, and a sensor is installed in the blender housing that measures the actual speed of rotation of the nozzle and its position in space, while the blender contains a wireless data transceiver module for communication with a portable device with an installed application, and the speed of rotation of the nozzle is determined by means of a Hall sensor installed on the motor shaft, and the ability to determine the position of the nozzle in space is carried out by means of a built-in gyroscopic position sensor .

In turn, a portable device with an installed application receives, processes and displays the data transmitted by the blender, including the speed of rotation of the nozzle.

At the same time, the portable device with the installed application processes and displays data, providing statistics on the history of use in offline mode.

Using a portable device with an installed application, data is transmitted that allows programming the assignment of buttons located on the blender body in the mentioned application.

Also, using a portable device with an installed application, the state of the blender is monitored in the said application.

In addition, the control of the state of the blender in the mentioned application is carried out on the basis of the actual speed of rotation of the nozzle, obtained on the basis of the data transmission provided by the Hall sensors mounted on the motor shaft.

In turn, it is possible to control the position of the blender in space using the built-in gyroscopic position sensor, which allows the blender to turn on only if the blender nozzle is directed downwards, and also allows the blender to automatically turn off if the nozzle changes its position in space during operation.

In this case, any portable computer device, such as a smartphone, communicator, tablet computer, laptop, smart watch, can be used as a portable device.

In addition, the reception and transmission of data between the portable device and the blender device is carried out using any type of communication / connection, such as Wi-Fi, and / or Bluetooth, and / or mobile cellular communication GSM, 3G, 4G, LTE, and / or via ultra-low power data links forming complex wireless mesh networks such as ZigBee and/or LoRa and/or LoRaWAN and/or LPWAN and/or 6LoWPAN and/or Z-wave.

The problem is solved, and the required technical result when using the invention is achieved by the fact that the method of operation of a submersible hand blender controlled by a wireless data transfer protocol is that the nozzle is fixed on the blender, the blender is connected to the mains, the nozzle is immersed in the product being prepared, with In this case, the blender contains a wireless data transmission and reception module through which it communicates with a portable device with an installed application, to which data is transmitted, including the speed of rotation of the nozzle, while determining the rotation speed of the nozzle is carried out by means of a Hall sensor installed on the motor shaft, and the ability to determine the position of the nozzle in space is carried out by means of a built-in gyroscopic position sensor, while it is possible to program the assignment of the buttons located on the blender body in the mentioned application, as well as the ability to control For the state of the blender in the mentioned application.

Implementation of the invention

It was found that in order to solve the problem and achieve the technical result, it is necessary that the device of the hand-held immersion blender with wireless control contains a sensor that measures the actual speed of rotation of the nozzle and determines the position of the nozzle in space. At the same time, data on the actual speed of rotation of the blender nozzle and its spatial position are wirelessly transmitted to a device for receiving, processing and outputting information, such as a portable computer device with a touch screen.

As will be described below, the claimed hand immersion blender includes a sensor that measures the actual speed of rotation of the nozzle and its position in space. The blender also contains a wireless data transmission module for communication with any portable computer device, such as a smartphone (mobile phone with the functionality of a pocket personal computer), a communicator (a pocket personal computer with the functionality of a mobile phone), tablet computer, laptop, smart watch . At the same time, on a portable computer device, it is necessary to install an application to which data is transmitted, including the speed of rotation of the nozzle. As an example, this could be the Polaris IQHome app.

As shown in FIG. 2, the nozzle rotation speed is determined by means of a Hall sensor mounted on the engine shaft (shown in the drawing as a speed sensor 10 with a Hall sensor). In turn, the ability to determine the position of the nozzle in space is carried out by means of a built-in gyroscope (see Fig. 2 item 9).

The use of such a simple and reliable converter as a Hall sensor mounted directly on the shaft makes it possible to reliably and accurately determine the direct speed of rotation of the blender nozzle immersed in the processed product. Prior art models of immersion blenders allow you to set only the speed of rotation of the blender nozzle. At the same time, none of the known submersible blenders can determine at what actual speed the nozzle rotates depending on the density and composition of the products mixed in the bowl. The claimed blender with wireless control, connected to the application, controls not only the set, but the actual speed of rotation of the nozzle, through the use of an additional sensor - a Hall sensor installed on the shaft, the data of which is transmitted to the application so that the values obtained can be available to the application to the user for precise adherence to recipe parameters.

The use of a built-in gyroscope to determine the position of the nozzle in space increases the reliability of determining the absolute position of the nozzle in space. Controlling the position of the blender in space using the built-in gyroscope provides the ability to disable / enable the blender. That is, the declared blender, when used, will turn on only if the blender nozzle is directed downwards. In the event that during operation the nozzle sharply changes its position in space, the blender will turn off. Thus, the use of the built-in gyroscope will not only increase the level of user protection from possible injuries resulting from careless handling of the rotating parts of the blender, but also provide additional convenience, which is expressed in preventing splashing of products when removing the blender from the bowl.

Also in the claimed blender, it is possible to program the assignment of buttons (positions 2 and 4 in Fig. 2) located on the blender body. In particular, said application, for example, the Polaris IQHome application installed on any portable computer device, such as, for example, a smartphone (mobile phone enhanced with PDA functionality), communicator (Personal Pocket Computer enhanced with mobile phone functionality), tablet computer, laptop, smart watch allows you to set various functions of the smart button 4, which simplifies the use of the blender, and can also increase the reliability and safety of the blender, for example, due to the fact that the user can select one of the preset ones in the application or create his own personal work cycle blender (rotation speed, pulse, pauses), transfer it from the application to the blender and start it by pressing the "smart" button 4. In this case, it is possible to assign any of the buttons 2 or 4 to an operational function that ensures safe use, for example, the speed reduction function or engine stop. Shown in FIG. The example in Figure 2 considers button 4 as the smart button, but this is only one choice. According to the proposed invention, the user himself can choose in the application which of the buttons 2 or 4 will be assigned to him as a "smart" button, guided by personal requirements for ergonomics, that is, his own requirements for the convenience and comfortable use of the blender. At the same time, it is obvious that other functions can be assigned to the mentioned buttons 2 and/or 4 in the application - turning on the engine, selecting a work program, increasing speed, etc., or, for example, activating some additional functionality of the device. In addition, as mentioned above, the user can either select one of the pre-installed ones in the application or create his own personal blender operation cycle (rotation speed, pulsation, pauses), transfer it from the application to the blender and start it by pressing the "programmable" button.

Thus, it is possible to program the assignment of the buttons located on the blender body in the mentioned application.

In addition, the present invention implements such a possibility as the ability to control the state of the blender in the above application, which also improves the reliability and safety of the blender. For example, the user will be able to visually see how the selected mode of operation corresponds to the technical characteristics of the blender, which will help to avoid overheating and triggering of emergency protection against overheating. This function provides additional user safety during the use of the device, and also informs him about the reasons for the protection operation if the user ignored the warnings coming from the application and allowed the device to overheat.

In FIG. 2 it is also indicated that each replaceable nozzle has its own code, and when it is installed in the blender body, the nozzle code is read using the nozzle code reader 12. The specified control of the type of nozzle installed allows the user to open access to additional blender operation modes in the application, including such modes that will not require constant holding while the blender button is operating. This is especially true, for example, in cases where it is necessary to beat / mix / grind the product when working in the same mode for a long time.

The replaceable nozzle (3, 3.1, 3.2) is driven by an electric motor 11, on the shaft of which a Hall sensor is installed that controls its speed (see speed sensor 10 in Fig. 2). A gyroscopic position sensor 9 is built inside the blender body, which makes it possible to control the position of the blender in space.

Thus, the claimed blender has a programmable unit 8 that transmits and receives data to/from a portable computer device capable of transmitting and receiving high-frequency radio waves using a wireless local area network, such as a smartphone (mobile phone supplemented with the functionality of a pocket personal computer), communicator (personal pocket computer, supplemented with the functionality of a mobile phone), tablet computer, laptop, smart watch (see Fig. 3 position 5).

In particular, the Internet can be used as a wireless network, and/or mobile or satellite communications, Bluetooth, and/or Wi Fi, and/or GSM, 3G, 4G, LTE, and/or wireless communication can be carried out via ultra-low power data links forming complex wireless networks with a mesh topology, such as ZigBee and/or LoRa and/or LoRaWAN and/or LPWAN and/or 6LoWPAN and/or Z-wave.

In turn, a program is loaded onto the portable device 5, which allows the blender to work and has a simple interface that is understandable to a user of any level. The application cites the Polaris IQHome application as an example. It should be understood that any other programs can be developed or known applications can be supplemented that will allow operation with the claimed device of a wireless hand-held immersion blender controlled by a wireless data transfer protocol.

In addition, the portable device receives, displays and processes data not only in real time. It also provides usage history statistics, meaning the portable device can work offline as well.

The communication scheme of a wireless blender 1 with wireless control and a portable device 5 is shown in FIG. 3.

The claimed blender works as follows.

The replaceable nozzle 3 is fixed on the blender 1, the blender 1 is connected to the mains, the nozzle is immersed in the prepared product. When the blender is turned on, the nozzle code is read and the information is wirelessly transmitted to the application installed on the portable device 5, such as a smartphone. Transmission and reception of data between the portable device and the blender device is carried out, for example, using a WLAN (Wireless Local Area Network - wireless local area network), using high-frequency radio waves for communication and data transmission between nodes, for example, Wi-Fi wireless local area network technology with devices based on IEEE 802.11 standards or using any type of communication (connection) that are described in the framework of the present invention (Bluetooth, and / or GSM, 3G, 4G, LTE mobile cellular communications, and / or via ultra-low power data transmission channels, forming complex wireless networks with mesh topology, such as ZigBee and/or LoRa and/or LoRaWAN and/or LPWAN and/or 6LoWPAN and/or Z-wave). At the same time, after connecting to the application, the following functions become available to the user, namely:

• Possibility to switch on/off control of the position of the blender in space using the built-in gyroscope to increase the level of protection against possible injuries resulting from careless handling of the rotating parts of the blender, to simplify and increase the reliability of use, expressed in preventing splashing of products when removing the blender from the bowl - use of a gyroscope will allow the blender to turn on only if the blender nozzle is directed downwards, and also turn off the blender if the nozzle changes its position in space during operation.

• Nozzle rotation speed control by means of a Hall sensor installed directly on the shaft, which allows you to find out with what actual speed the nozzle rotates depending on the density and composition of the products mixed in the bowl. The blender connected to the application monitors not only the set but the actual speed of rotation of the nozzle, using a Hall sensor mounted on the shaft, and transmits the obtained values to the application for exact compliance with the recipe parameters.

• After connecting to the application, one or more of the buttons on the blender body becomes "smart". The user will be able to select one of the pre-installed ones in the application or create his own personal cycle of the blender (rotation speed, pulsation, pauses), transfer it from the application to the blender and start it by pressing the "smart" button or their combination;

• Recipes in the app also allows the user to access a database of recipes for the blender, which he can transfer from the app to the blender and run by pressing the "smart" button;

• Monitoring the current state of the blender in the application - the user will be able to clearly see how the selected mode of operation corresponds to the technical characteristics of the blender, which will help to avoid overheating and triggering emergency protection against overheating. This function provides additional safety and reliability of the device use, and also informs it about the reasons for the protection operation if the user ignored the warnings coming from the application and allowed the device to overheat.

• Control of the installed nozzle type - depending on the installed nozzle, additional modes will be available to the user, including those modes that will not require constant holding of the blender button during operation.

Thus, the claimed wireless blender improves safety and reliability, and also simplifies the use, that is, the claimed result is achieved.
