Description

The utility model relates to devices for boiling drinking water in a domestic environment, namely to dummies.

Known electric kettle with a temperature timer containing a variable temperature timer (see RF application No. 2002121270, filing date 2002.08.12, publication date 2004.02.27. Applicant - Kuvakin E.YU.).

The well-known kettle does not provide sufficient convenience for the consumer to use, since it does not allow tracking the temperature of the water in the kettle.

The closest technical solution of the known ones is an electric kettle containing a base that supplies electricity, a liquid reservoir installed in the latter, an electric heating element, a temperature limiter, a heat-sensitive element and a power reduction system for a heating element with a mode switch, a thermal relay and a temperature sensor (see RF application No. 2001102370/13, filing date 2001.01.11, publication date of the application 2003.01.10 Applicant - Vyuzhujanin S. A. - prototype).

The well-known teapot is also not convenient enough for the consumer to use, since the consumer cannot track the temperature of the water in the teapot, which is very important for the consumer in domestic conditions.

In addition, the temperature regime of water can be changed in a limited temperature range.

Thus, as shown by the analysis of information on the current level of technology in this field, the known electric kettles do not provide sufficient convenience in use, because they do not allow the consumer to know at the right time the temperature of the water in the kettle, which is very important in domestic conditions.

Declared as a utility model, an electric kettle allows you to achieve a new technical result - increasing the convenience for consumers to use an electric kettle by ensuring that the temperature of the water in the kettle is monitored at any time and changes the water temperature in an unlimited range to the boiling point of water at any time.

The following set of essential features characterizes the essence of the proposed utility model.

An electric kettle containing a base for supplying electricity, a housing with a liquid tank with a handle, installed in the latter, an electric heating element located in the tank, a temperature limiter, a relay, a temperature sensor, and an operating mode switch, characterized in that it is equipped with a liquid crystal indicator located on the housing, an autonomous power source and a microprocessor control system, electrically connected to the latter, an operating mode switch, liquid crystal a female indicator, a relay and a temperature sensor.

To achieve the result, a microprocessor control system is built into the handle of the fluid reservoir.

The technical result is achieved by the fact that the mode switch is located on the kettle body.

Thus, as shown by the analysis of the revealed information in this area and the essence of the proposed utility model, the latter meets the patentability criterion of “novelty”.

Providing the kettle with a liquid crystal indicator located on the body and a microprocessor control system built into the handle and electrically connected to the operating mode switch, a liquid crystal indicator, a relay and a temperature sensor allows you to monitor the temperature in the kettle at any time and simply, it is easy to adjust the water temperature in unlimited range to the boiling point of water at any given time.

Thus, the claimed combination of essential features of the proposed utility model provides a new technical result in all cases to which the requested amount of legal protection applies.

The proposed electric kettle is illustrated using the drawing, where:

figure 1 - shows an electric kettle;

figure 2 is a circuit diagram.

The electric kettle contains a base 1, a housing 2 with a liquid tank 3 with a handle 4 and a cover 5, an electric heating element 6, a temperature limiter (not shown in the drawing), a temperature sensor 7, a microprocessor control system (MCM) 8, an electronic relay 9 located from the inside of the housing 2, a liquid crystal indicator 10, a switch 11 of the operating modes and an autonomous power source 12, which is a battery or battery.

A temperature limiter is necessary to turn off the power supply to the electric heating element 6 when the boiling point of water is reached.

Base 1 is designed to supply electricity to the electric heating element 6 through an electronic relay 9 and a microprocessor control system 8.

The liquid crystal indicator 10 and the switch 11 of the operating modes are located on the housing 2.

The liquid crystal indicator 10 is designed to display the temperature of the water in the tank 2, which allows the consumer to know the temperature at any time.

The switch 11 modes of operation is designed to change the temperature of the water in the kettle by the user in an unlimited range to the boiling point of water at any time. The switch 11 is an electronic board with control buttons displayed on the housing 2, designed to discretely establish the required temperature for heating the liquid (conditionally “-” “+”) and turn on the electronic relay 9 to supply electric power to the heating element 6 (conditionally the power button) .

A microprocessor control system 8 (see Figs. 1, 2) is built into the handle 4 of the water tank 3 and is electrically connected to an autonomous power supply 12, an electronic relay 9, a temperature sensor 7, a liquid crystal indicator 10, and an operating mode switch 11. The microprocessor system 8 is made on the basis of any domestic microprocessor in the form of a board with analog-to-digital input 13 and digital-to-analogue output 14.

Electric kettle operates as follows.

When the base 1 of the electric kettle is turned on, power is supplied to the electric heating element 6, from an autonomous source 12 to the microprocessor control system 8. Using a temperature sensor 7 electrically connected to the ICM 8, the temperature of the water in the tank 2 is converted into the ICM 8 into a signal and is displayed on the liquid crystal indicator 10 as an indicator of the temperature of the water in the kettle.

Using the switch 11 operating modes, the user sets the desired temperature of the liquid and turns on the electronic relay 9, after which the process of heating the liquid in the kettle.

In the process of heating the liquid from the temperature sensor 7 there is a signal in the ICM 8 about the actual temperature of the liquid and is compared with the user-specified. In case of mismatch between the actual and the set temperatures, the electronic relay 9 remains on. When

temperature coincidence ICC 8 sends a signal to the electronic relay 9 and it turns off, thereby stopping the process of heating the liquid.

Thus, as a result of the application of this utility model, it is possible to obtain a new technical result - increasing the convenience for the consumer in using an electric kettle by ensuring that the temperature of the water in the kettle is monitored at any necessary time and the water temperature changes in an unlimited range to the boiling point of water in any moment of time.

Therefore, the proposed utility model meets the patentability criterion of "industrial applicability".
