Description

FIELD OF TECHNOLOGY

The present technical solution relates to devices intended mainly for boiling liquid, in particular water, such as a kettle, thermopot, electric samovar and the like.

LEVEL OF TECHNOLOGY

An electric water heater is known (CN201022621Υ dated 02.22.2007, IPC class A47J27 / 21; A47J27 / 212). Electric water heater is made of glass, organic glass or plastic; the correct position of the outer casing of the electric water heater is ensured by a backlight plate, and the lower part of the outer casing of the electric water heater is equipped with a temperature indicator, the inner side of which has a programmable microcircuit and an inductive temperature sensor. The output of the inductive temperature sensor is connected to the input of the programmed microcircuit, and the output of the latter is connected to the input of the backlight plate. An inductive temperature sensor measures the temperature of the water in the water heater and transmits the data to a software-controlled microcircuit, which sends commands to the backlight plate to turn on the backlight in different colors depending on the temperature of the liquid.

The disadvantage of this electric water heater is the complexity of the perception of the light indication from angles of view other than the top view, and the lack of indication of the liquid level.

Known vessel for heating a liquid (GB2402325A from 25.09.2003, class A47J27 / 21; A47J27 / 212; A47J27 / 21), which contains a housing and at least one light source installed in a transparent housing located inside the specified vessel housing. The transparent body protrudes into the liquid in the vessel during use, thereby allowing direct transmission of light from the light source to the liquid. Each light source can be neon, LED, or conventional incandescent. One light source can be illuminated while heating by the main element and the other can be illuminated while the liquid is kept warm with a lower wattage heater. They can be of different colors.

The disadvantage of this vessel for heating liquid is uneven and spot illumination of water, since there is no brightness control.

Known kettle (PCT / GB2001 / 000392 from 09.08.2001, class IPC A47J 27/212) with electric heating or a jug of hot water having a thick-film heating element equipped with PTCR elements that generate alternating voltages when the heating element is heated in use, and these voltages are used to drive the corresponding diodes of the LED array so that the array glows more and more as the temperature rises. The color of the LEDs ranges from green (cold) to yellow / orange (warm) and red (hot) and can illuminate the sight glass of the vessel or the contents of the vessel, in which case the vessel wall has at least one transparent part. Having such a display on a kettle or jug with bimetallic controls provides a "high tech" look to a device that is technically uncomplicated in nature and makes it attractive compared to more expensive electronically controlled devices.

The disadvantage of this kettle is the uneven and spot illumination of the water, since there is no brightness control.

Known luminous teapot (CN 103784007 from 05/14/2014, class IPC A47J 27/21), containing a teapot body; a touch sensor and a ring-shaped LED lamp (light emitting diode) are located in the center of the upper lid of the kettle; a frame-shaped LED lamp is located on the periphery of the water level display screen, which is located on the side wall; the touch sensor circuit is connected to a ring-shaped LED lamp and a frame-shaped LED lamp; When the user touches the top lid of the kettle, the touch sensor controls the LED lights to light up.

The disadvantage of this glowing kettle is the uneven and spot illumination of the water, since there is no brightness control.

Known water heating device (RU2014147784 from 03.07.2013, class IPC A47J27 / 21), containing a heating element, a level sensor configured to determine the state when the water heating device is empty, and a transceiver that provides the ability to turn on and off the said heating element at a distance by sending by the user to the said transceiver of the corresponding command signal using a mobile communication device, while the time during which the boiling of the contents of the water heating device is achieved is determined either on the basis of data set by the user or on the basis of parameters according to a given formula.

The disadvantage of this water heating device is the lack of installed water backlighting.

Known electric kettle (EP 1597989 B1 of 06/18/2004, class IPC A47G19 / 14; A47J27 / 21; A47J27 / 212; A47J31 / 54; A47J), including a water-containing vessel having a bottom and a window, an electric heating element located relative to the vessel in such in order to transfer heat to the water contained therein, a temperature sensor for measuring the temperature of the water inside the vessel, light emitters shining into the vessel to illuminate the water therein, each light emitter having different color emission characteristics; as well as an electrical circuit associated with a temperature sensor and each light emitter, which controls the operation of each emitter to illuminate the water in such a way that below and above the first temperature, the water is illuminated, respectively, with the first and second colors, characterized in that each light emitter contains an LED located inside a casing that tightly passes through the bottom of the vessel.

The disadvantage of this electric kettle is the uneven and spot illumination of the water, since there is no brightness control, in addition, there is no wireless control.

A known vessel for heating a liquid (EP2661994 B1 dated 09/14/2016, class A47J27 / 21083, A47J27 / 2105, G05D23 / 1905, G05D23 / 22, G05D23 / 24, G05D23 / 27, A47J 2203/00, A47J31 / 52, H01H36 / 02 ), taken by its technical characteristics as a prototype, in which a reservoir for heating a liquid is provided, including a user interface embodied in a remote control device, which can also provide status indication and can include at least some of the functions of controlling the vessel. There is also an intermediate device that communicates with the vessel and with the remote control device and may provide additional functionality. For example, an intermediate device can provide information to a vessel that cannot be obtained from a remote control. An intermediate device may be provided between the power supply and the container and may include a power switching function. The intermediate device can determine the property of the vessel or its contents.

The disadvantage of this vessel is the need for a separate device for remote control attached to the vessel, limited functionality of the remote control device, expressed in the need for an intermediate device, uneven and spot illumination of water, since there is no brightness control, no feedback between the liquid level indication and the light indication.

The objective of the proposed technical solution is to create a device for heating a liquid with wireless control, providing adjustment of the brightness of the backlight either through automatic mode using a light sensor, or remotely using a mobile communication device with a remote control.

An example of the implementation of the technical solution is shown in Fig.1-4.

The bulb (1) can be made of glass, organic glass, plastic or metal material. The flask itself (1) is closed with a lid with a silicone seal. Structurally, depending on the model of the device for heating water, the cover (2) can be removable or non-removable.

The heating element heating element made of stainless steel, installed inside the bottom (3) of the flask (1), is made in the form of a spiral or plate.

The bulb (1) itself is mounted on a body (4), which is made of light-scattering plastic, but can also be made of other materials such as plastic and glass. A reflector (5) is installed inside the housing (4), which is responsible for ensuring light reflection. The reflector (5) is predominantly white, since white reflects better (as opposed to black, which absorbs) and does not change the shade of light. Structurally, the reflector (5) also in some models of the device for heating water can be made transparent or mirrored. The lower part (6) of the housing (4) allows the placement of auxiliary parts, such as load cells (8).

The backlight board (7) is installed inside the case (4) on the lower part of the case (6) and is a printed circuit board with digital RGB LEDs. The number of LEDs is more than 2, which should provide a smooth, uniform light line with an equal LED pitch along the diameter of the bulb (1).

Load cells (8) are strain gauges that measure force and load and are located in the lower part of the housing (6). The number of strain gauges (8) must be even, with a uniform distribution along the bottom of the body (4) to evenly distribute the weight of the flask (1) with water. Plugs (9) are installed on top of the load cells (8), ensuring their safety and protection.

The very bottom of the case (6) is mounted on a base / stand (10), which is a plastic product with a Strix contact pair, a power cord and rubber feet.

A handle (11) is installed on the flask (1) for holding it in the hands. On the handle (11) buttons (15) are installed for turning on / off, as well as adjusting the settings of the device for heating water. Buttons (15) can be tact or touch.

The power board (12) is a printed circuit board with components and is installed in the handle of the flask 1 (11), it provides power to all electronic components of the device for heating water.

The handle cover (13) provides protection for components such as the power board (12) and control board container (14) installed inside the handle (11).

A container with a control board (14) is installed inside the handle (11) and provides control of the functionality of the device for heating water directly through communication channels, such as BLE and Wi-Fi.

The temperature sensor (16) installed on the bottom of the flask (3) is a thermistor through which the water temperature is measured.

The seal (17) is made of silicone and is installed in the bottom of the flask (3).

When connected to a device for heating water from a smartphone, the application will display the volume and temperature of the water in the device. Illumination is provided by 24 digital RGB-LEDs through the body pos. 4 and the bulb pos. 1. An illumination sensor is installed on the control board (not shown in the figure), depending on the illumination, the illumination is brighter / dimmer. The light sensor is, for example, a photocell.

The claimed technical solution works as follows.

User 1 parks the car, connects from his electronic device, such as a mobile phone, to an indoor water heating device via a communication channel, such as Wi-Fi, via a mobile application, using a Gateway device installed at home that converts Wi-Fi Fi signal in BLE, allowing you to control the device for heating water from anywhere in the world, while leaving a secure connection with the equipment through the BLE channel. User 1 wants to start the boiling process with the water heater so that when he comes home the water is already hot.

On the application screen, User 1 sees the level of water in the kettle and realizes that there is not enough water. User 1 calls User 2 and asks to add water to the device. User 2 performs this action, while the claimed device itself stands on the base. User 2 observes how the LED ring gradually changes from blue to blue at the 1.7 liter mark User 2 stops pouring water into the kettle. With the help of the control located in the handle of the device, User 2 turns on the "Heating + Boil" mode, choosing the water temperature to maintain after boiling 60 degrees. During boiling, User 2 sees on the LED ring a smooth change in colors from the palette set in the mobile application: the color changes from yellow to green and through white returns to yellow again. Upon completion of boiling, the kettle's backlight changes to purple, corresponding to a temperature of 60 degrees.

User 2 opens the tea cupboard and discovers that it will run out soon, presses the clock button on the teapot to auto-order his favorite Greenfield Earl Gray Tea pre-installed on the application and waits for a call to confirm the order.

User 1 gets out of the car and in the application sees the process of boiling water, he rushes home to be in time for the end of boiling. Entering the room and pouring tea, User 1 turns on his favorite "Night Light" mode from the application, having previously set the entire spectrum of colors for a smooth transition for this mode, each LED gradually changes color, creating a feeling of rainbow light illumination in the lower part of the body of the claimed device.

User 1 presses the tact button on the kettle and thereby ends the session with the kettle. User 2 turns off the light in the room and the brightness of the LEDs is gradually dimmed thanks to the light sensor installed in the handle of the device.

The claimed technical solution, namely a device for heating a liquid with wireless control, backlight, indication and function of determining the amount of liquid, provides the possibility of remote operation. This technical solution improves the usability of the device for heating a liquid by displaying complete information, such as the liquid level in the vessel, liquid temperature, device readiness for operation, presetting liquid heating, etc., on the screen of a mobile communication device (smartphone, tablet, etc.) etc.). Information about the temperature of the liquid and its volume is displayed visually by means of a backlight, the brightness of which is automatically adjusted depending on the level of illumination, which increases the ergonomics of the device. Remote control and illumination increase the safety of the device by protecting the user from thermal burns or electric shock, as well as from the so-called dry boiling when there is no liquid in the vessel. The device makes it easier to care for young children by conveniently adjusting the settings for preparing baby food, and also helps to maintain a healthy lifestyle by tracking the amount of fluid consumed.
