Description

The claimed technical solution relates to electrical household heating devices and can be used for hygienic water procedures in case of interruptions in the operation of the hot water supply system, as well as in the absence of a water supply system.

Three types of electric water heaters are known from the current level of technology - flow, storage and bulk. Flowing and storage electric water heaters can be used only with a water supply system: they are built into the cold water supply system.

A flow-through electric water heater is a type of water heaters in which water heats up immediately as it passes through a water heater. Known electric heater, which is made in the form of a heating module, which includes a tubular housing with inlet and outlet pipes, heating elements with sealing units, installed inside the housing coaxially along the entire length of the housing with a gap of 1.0-2.5 mm, a water presence sensor in the housing, made in the form of a pressure signaling device, the sensitive element of which is connected by a hydraulic channel to the internal cavity of the housing, a thermal limiter and a light indicator of the operation of the heating element (RU, з. No. 97101790/06, F24Н 1/20, dated 06.02.1997, publ. 27.09 .1998). A flow-through electric water heater is designed for instant heating of water continuously coming from the water supply network. It is characterized by high speed, but due to the high energy consumption at the time of heating the water, it requires the connection of a separate electric cable from the electrical panel to the water heater. Its disadvantages include difficulties associated with maintaining a constant temperature, stringent requirements for a minimum inlet water pressure.

Accumulative electric water heater is a type of water heaters equipped with capacious heat-insulated containers in which water is heated using the built-in heating element (TENA) before being supplied to the mixer or shower. When draining hot water, it is gradually replaced by cold water coming from the water supply. A well-known storage electric water heater, which contains a steel outer casing, two containers made of aluminum, connected in series between each other by an adapter pipe, a heating element with a thermal switch installed in each container, a cold water supply pipe with a non-return safety valve in one tank, and a hot intake pipe water and a complete drain pipe in another container, and on the front of the outer case there is a control panel with a temperature control knob, a button Starting the operation modes of the heating elements and light indication (RU, s. №2008135528 / 22, F24N 7/00, on 04.09.08, publ. 10.01.09). Accumulative electric water heater is used to heat large volumes of water, because after emptying the volume of containers by 1 / 2-2 / 3, the outlet jet becomes cool due to the cold water entering the tank. The disadvantages of the storage electric water heater include its dimensions, prolonged heating of water, the need for regular maintenance.

A bulk electric water heater is a type of water heaters used in the absence of a water supply system: in houses without a water supply system, in garages, in summer cottages. The design of the bulk water heater includes a tank (usually up to 30 l) equipped with a crane, a heater and a temperature controller. Bulk water heaters are usually placed above the sink. The closest analogue - a prototype to the claimed technical solution is a household electric heater, which contains a plastic container with a removable lid, an electric heater located in the lower part of the tank, a drain device, electrical components and a temperature controller with a handle located on one of the side walls or on the base containers and closed by a box casing, a suspension device in the form of support brackets, and the container contains fixing elements on the suspension device (RU, z. No. 2009143422/22, P24H 1/20, from 23. September 11, publ. 04/27/10). Water is poured into the tank manually with the cover removed. The required water temperature is set with the temperature control knob. When water is heated to a predetermined temperature, the temperature controller turns off the electric heater, and when the water temperature in the tank decreases, it automatically turns it on. Water is taken from one level: a drain device located above the electric heater. The disadvantage of this water heater, which is inherent in other bulk electric water heaters, is the instability of the temperature of the flowing stream of water due to the temperature separation of water in the tank. When heated, the water “stratifies”: at the top there is a warmer layer, at the bottom it is colder. Therefore, the stream of water flowing out of the tank is first cool, then warm, and then hot. Hence the low consumer-operational characteristics and the functional limitations of bulk electric water heaters: they are positioned as a “heated washbasin”.

When taking hygienic water procedures and, in particular, the shower, the most important characteristic of the comfort of the procedure is the temperature stability of the flowing stream of water.

The utility model is based on the task of creating a device for conducting hygienic water procedures during interruptions in the operation of the hot water supply system, as well as in the absence of a water supply system, combining comfort, economy, compactness, mobility, ease of operation and maintenance.

To achieve this objective, a device is proposed for a water heater-shower, which, like the closest to it, a household electric heater selected as a prototype, contains a container with a removable lid, an electric heater (TEN) located in the lower part of the tank, a control unit with a temperature regulator having a handle adjustment, equipped with a temperature sensor with an LCD display, an indicator of filling the tank with water, a device for simultaneous water intake at two levels, the output end of which is placed in the drain hole and, a shower hose and a watering can with a push control button, a water inlet hose, a hanging shelf.

In this case, the controls are located on the front side of the tank.

In addition, water is withdrawn simultaneously at two levels: from the upper and lower layers of water.

In addition, the LCD displays in figures the temperature of the water from the temperature sensor installed in the tank above the intake from the lower layers of water.

In addition, the inlet hose is connected to the bath mixer.

In addition, the removable lid of the container has a receiving hole for the inlet hose.

The technical result of the claimed device is to ensure the stability of the temperature of the flowing stream of water due to the simultaneous intake from the upper and lower layers of water in the tank.

The technical result is achieved by the fact that the electric water heater-shower device is equipped with a device for simultaneous water intake at two levels, consisting of a funnel, float, intake pipe and L-shaped fitting. Water is taken from the upper layers through the funnel, and from the lower through the longitudinal grooves on the outer cylindrical surface of one of the ends of the L-shaped fitting located in the drain hole of the tank.

As a result of the implementation of the proposed design, the functionality is expanded, the consumer-operational characteristics of the domestic electric heater and the level of comfort are increased.

The placement of the control unit, as well as the thermostat, in the lower part of the tank and the location on the front side of the tank of control elements, i.e. adjustment knobs of the thermostat, a key switch with a signal lamp and an indicator for turning on the heater, provides convenience during operation of the device.

The introduction of a temperature sensor with an LCD display provides information on the actual temperature of the water in the tank, which allows to optimize the temperature regime of water procedures and save energy.

The introduction of a tank filling indicator with water installed on a removable container cover makes the process of monitoring the water level when filling the tank comfortable.

The introduction of a shower hose, shower head with a push-button control expands functionality and provides an economical mode of water flow.

The introduction of the inlet hose makes the process of filling the tank with water comfortable.

The introduction of the inlet opening for the inlet hose on the removable lid of the container and the hanging shelf provide ease of installation of the container and its durability.

As a result of the patent research, no similar technical solutions were identified, characterized by the claimed combination of features, which allows us to conclude that the claimed technical solution has novelty and is industrially applicable.

The device operates as follows. The inlet hose 19 is connected to a bath mixer. The other end of the inlet hose 19 is inserted into the inlet opening of the removable cover 2. Open the mixer valve and fill the container 1 with water, following the flag 10 of the tank fill warning indicator 9. When the flag is raised above the removable cover, which indicates that the container is full, close the mixer valve and remove the end of the inlet hose 19 from the inlet (in the absence of a water supply system, the tank is filled with water manually through a funnel inserted into the inlet of the removable cover). They turn on the device in the power supply network and use the key switch with the signal lamp 6 to supply voltage to the electric heater 3. The temperature control knob 5 sets the required temperature. When the temperature regulator is turned on, the heating element ON indicator lights up 7. When the water is heated to the set temperature, the temperature controller turns off the electric heating element 3. The temperature of the water in the tank is controlled by the LCD 8. If necessary, adjust the heating of the water with the adjustment knob 5. When the water temperature in the tank 1 decreases , the thermostat automatically turns on the electric heater 3 and the heating process is repeated. Before taking water procedures, the device is disconnected from the power supply and the ball valve 15 is opened. The intensity and continuity of the outflow of water from the tank, when taking water procedures, is regulated by the control push button 18 of the shower head 17.
