Description

[0001] DESCRIPTION

[0002] DEVICE FOR HEATING DRINKING WATER

[0003] The field of technology to which the utility model relates.

[0004] The claimed utility model relates to methods and devices for heating a given volume of water to a desired temperature, for example, to obtain warm water or to obtain a certain amount of water.

[0005] State of the art

[0006] The following technical solutions known from the state of the art can be identified as analogues.

[0007] An electric kettle is known which comprises a base, a body with a bottom mounted on the base, a current lead, a heater, a microcontroller, to the output of which a relay is connected, the switching circuit of which is connected between the current lead and the heater, and a switching element, a boiling sensor and a force sensor connected to the input of the microcontroller, the force-sensing elements of which are installed with the possibility of interaction with the base and the bottom. Moreover, the part of the bottom interacting with the force sensor is made with the possibility of displacement and / or deflection under the force of gravity of water, and the force sensor is made integral with the boiling sensor (patent RU2462975, IPC A47J 27 / 21, published 10.10.2012).

[0008] The disadvantage of the known device is the lack of visual information about the water temperature.

[0009] A device for thermal processing of products is known, comprising a main body with a vessel provided in its lower part with a heating element and a thermal fuse, and a base connected during use to a power source, wherein a plug part of an electrical connector is made on the central upper part of the base, and a socket part of the electrical connector is made on the bottom of the main body. Inside the main body with a gap, a vessel is placed, coated from the inside with a non-stick layer and hermetically connected to the upper part of the body through a heat-resistant sealing ring, a heat-reflecting screen is placed between the bottom of the vessel and the bottom of the body with a gap, a thermal fuse and a temperature sensor are connected to the heating device, which in turn are connected to the socket part of the electrical connector, and a power supply and control module is used as the base, containing a control unit connected to a keyboard, a display, a speaker,a pressure sensor, a plug-type electrical connector, a power source, a transceiver configured to be connected via either radio or infrared communication to a transceiver of a remote control, and the electrical contact of the remote control is configured to be connected to an electrical contact of a power supply module of the remote control connected to a power source (patent RU66166, MIIKA47J27 / 00, published 10.09.2007).,

[0010] The disadvantage of the known device is the limited visibility of information about the water temperature, boiling or reaching the set water temperature.

[0011] Disclosure of the essence of the utility model

[0012] This useful model is designed to reduce the time it takes to heat the liquid to the required temperature, extend the service life of the heating element and save electricity. Another advantage of this method is its convenience for the consumer, as he has the opportunity to get the amount of water he needs and the desired temperature.

[0013] The advantage of the development is a single boiling of water directly in the container itself. Multiple boiling of water, for example in a kettle or coolers leads to an increase in the content of nitrates, arsenic and sodium fluoride, heavy hydrogen and harmful organochlorine compounds are formed, the water changes its taste, the concentration of heavy metals increases, calcium salts become dangerous. Saving electricity, since for example there is no need to boil a full kettle. No scale, as a result of which the heating element lasts much longer.

[0014] The technical result is achieved as follows: a container with water is installed in the device; the desired action is selected on the touch screen; then the presence of the container is determined by the distance sensor integrated into the tray and if the container is present, the lid is automatically lowered, with a heating element, temperature sensor and water level sensor integrated into it, onto the container with a tight fit, thereby the heating element with sensors is inside the container with water.

[0015] Next, the tank is automatically filled with water to the level set on the touch display until the water level sensor is triggered.

[0016] The next step, if the action “Filling the container with water without heating” was previously selected, the lid with the heating element, temperature sensor and water level sensor integrated into it automatically rises upwards so that the container with water can be removed. Thus, the action is completed.

[0017] During operation, the controller constantly checks the readings from the humidity and temperature sensor located inside the case, and if the set values ​​are too high, automatic ventilation occurs using a fan built into the case to remove excess moisture and cool the internal elements of the device.

[0018] Also, during operation, the controller constantly checks the readings from the outdoor lighting level sensor, thereby changing the intensity of the display backlight.

[0019] If the action “Filling the container with water and then heating it up” was previously selected, then the heating element heats up the water directly in the container with water to a preset temperature, which is measured by the temperature sensor. After heating the water to the set temperature, the lid with the heating element, temperature sensor and water level sensor integrated into it automatically rises up so that the container with hot water can be removed. Thus, the action is complete.

[0020] The water heating device consists of: a housing, on the front of which there is a touch screen for controlling the device and informing about the ongoing process. Below there is a recess for installing a container for filling it with water with subsequent heating or without heating.

[0021] Main elements of the device:

[0022] A housing with a lid, a tray, a sensor for measuring the humidity level and temperature inside the housing, a fan, a controller, a display, and a pump installed in it.

[0023] A cover with a heating element, a temperature sensor, a water level sensor, limit switches, a nut for connection with a screw transmission and a sleeve for sliding along guides integrated into its lower plane.

[0024] A tray for a water container with integrated metal guides and an electric motor with a screw transmission and a distance sensor to determine the presence of a container in the tray.

[0025] The lid is mounted on guides with a screw transmission integrated into the tray using the bushings built into it. The movement of the lid along the guides with a screw transmission is carried out using an electric motor integrated into the tray.

[0026] Automation of all processes occurs using a touch screen and an electronic controller located inside the device body.

[0027] The device operates as follows: A water tank is installed on the tray (1), the required heating and filling parameter of the tank is set on the display (2), an external light level sensor (3) is installed above the display, which regulates the backlight level, then a distance sensor for determining the presence of a tank (4) determines the presence or absence of a tank, if there is a tank, water is supplied to the water tank using a pump (5), all processes are automated using a touch screen (2) and an electronic controller (6), a fan (7) is needed to remove excess moisture and cool the internal elements of the device, connected to a humidity and temperature sensor inside the housing (8), after filling the tank to a specified level, an electric motor (9), along guides with a screw transmission (10), lowers the lid (I) with a temperature sensor integrated into it, a water level sensor,limit (final) switches with a heating element (12) fixedly fixed in its lower plane directly into the container for heating water.

[0028] The device can be connected directly to the water supply as a water source.

[0029] The essence of the utility model is explained by figures, where:

[0030] Fig. 1 - elements of the device.

[0031] Fig. 2 shows a device for heating drinking water in the switched-off position.

[0032] In Fig. 3 the water heating device is turned on.

[0033] Thanks to the technical solution, lowering the heating element directly into the container for heating water, all the tasks set by the utility model are achieved, namely, scale does not form on the heating element, since the heating element heats a small amount of water, and is not in the water constantly, from this also follows a saving of time in heating the water, since the water is heated exactly as much as the consumer requires and energy savings.
