Description

The utility model relates to sanitary equipment, designed for washing hands, washing, washing dishes with water heated to the required temperature, in the absence of a centralized water supply. It can be used in domestic premises, educational and medical institutions, retail outlets, hotels, food points, in garden houses and garages connected to the mains.

A known analogue of the claimed technical solution, the washbasin "Street", manufactured by the manufacturing company LLC "Metles", Russian Federation, (http://metles.ru). The washbasin consists of a support column on which a removable basin for collecting used water and a filling tank for clean water with a water pipe with an outlet tap are installed.

The washbasin is used as follows.

The tank is filled with clean water, the outlet valve is opened and the water is used continuously for its intended purpose, then the outlet valve is closed. Used water is collected in a basin for further disposal.

Common features of the claimed technical solution and the analogue are: a washbasin containing a support column with a removable basin for collecting used water, a filling tank for clean water and an intake pipe mounted thereon.

In the design of the analogue, there is no heating of the water used and a device for the dosed water flow.

An electric heater for hot water supply, for example, for washing, described in the patent for invention RU No. 2116580, IPC F24H 1/20, published July 27, 1998, containing the upper and lower tanks connected by two pipes, the lower tank being also selected, was also selected It is additionally equipped with a water discharge pipe with a tap and a heating element, for example, a heating element, located in the lower part of the tank cavity. The water intake pipe is fixed in the bottom of the lower tank so that its inlet end is located directly below the top of this tank. The output end of the first connecting pipe is brought into the lower part of the cavity of the lower tank in the zone of the heating element, and the second connecting pipe contains a valve and connects the bottom of the upper and the cover of the lower tank.

An electric heater is used as follows.

The valve of the second connecting pipe is opened to prevent the formation of an air plug in the lower tank and fill both tanks with cold water. To heat the water, the heater is turned on, the water is heated to the temperature set by the temperature controller, after which the water heating stops. Heated water rises, accumulates in the upper part of the lower tank and is fed into the water discharge pipe after opening the tap for use. As the heated water flows into the lower tank, cold water enters from the upper tank into the zone of the heating element, which, without mixing with preheated water, is heated to the temperature set by the temperature controller, rising to the upper part of the lower tank.

Common features of the proposed technical solution and the analogue are: a heating element (TEN) installed in the lower part of the lower tank cavity, a water intake pipe, the inlet end of which is located under the top of the lower tank, the output end of the first connecting pipe is brought into the lower part of the lower tank cavity in the zone of the heating element .

The disadvantages of this analogue are its high material consumption and the lack of thermal insulation of the lower tank, leading to increased energy costs for long-term maintenance of the set temperature of the water used.

As a prototype of a utility model, the Moydodyr washbasin complete with an EVBOE-15 / 1.25 “Summer H” electric heater, shown in the utility model certificate No. 79225, IPC Н05В 1/00 manufactured by Pskov Electrotechnical Plants OJSC ( http://elterm-pskov.ru.).

The washbasin comprises a support column on which a sink is connected, connected to a container for collecting used water, a filling tank with a dosed water flow device, the outlet of which is located above the sink, a water outlet pipe from the tank connected to a dosed water flow device. An additional tank is located in the tank, open from the bottom for water intake, in which a heater and a temperature controller are installed, and the inlet of the water outlet pipe is located directly below the top of the additional tank.

The washbasin is used as follows. The tank is completely filled with cold water and the heater is connected to the electric network. The heating element heats the water in the additional tank to the set temperature of the thermostat, which disconnects the heating element from the electric network. Heated water drawn through a water discharge pipe from the zone of greatest heating is supplied to a dosed water flow device that provides a flow rate of 0.5 liters per minute. In this case, cold water is supplied to the heating element from the tank through the open lower part of the additional tank, cooling the temperature control sensor. The temperature regulator connects the heater to the electrical network and the process of heating water resumes. The rate of heating water in an additional tank corresponds to the rate of analysis of heated water, so the temperature of the outflowing water remains almost constant when using the entire volume of water.

Common features of the proposed technical solution and prototype are: a washbasin containing a support column with a sink installed on it, a filling tank for clean water, a tap with a dosed water flow device, the outlet of which is located above the sink, a pipe for discharging water from the tank connected to the dosed flow device water, an additional tank installed inside the tank cavity, with a heating element and a temperature control sensor, the inlet of the water outlet pipe is located directly under the top of the additional water the cistern.

The disadvantage of this device is the high thermal conductivity of the surface of the additional tank, as a result of which there is a significant heating of the entire volume of water in the tank. This increases the energy consumption, especially when continuously maintaining the set water temperature in the “standby)) mode without using it. In addition, the possible formation of an air plug in the cavity of the additional reservoir (a drain pipe is not provided) can lead to failure of the heater, and to eliminate the air plug, you must first open the exhaust valve.

A significant disadvantage of this device is the lack of thermal protection of the heating element when it is turned on unauthorizedly without water, for example, before first use.

The problem solved by the proposed utility model is to save energy while maintaining the working temperature of the water used for a long time. This is achieved by the fact that the additional tank is made in the form of the lower part of the bulk tank, separated from its upper part by a horizontal sealed heat-insulating partition, for example, of solid foam, forming a closed volume of water above the heating element, sufficient for single use. In the partition, a tube is installed connecting the top of the additional tank with the top of the tank above the level of filling with water. Around the outer surface of the tank, below the partition, external thermal insulation is fixed.

The essence of the utility model is illustrated by the drawing in Fig., Which shows a section of the proposed washbasin.

The washbasin contains a rack 1 with a basin 2 mounted thereon for collecting used water, a filling tank 3 for clean water open from above. The hole for filling the water of the filling side in the working position is closed by the basin 2. In the rack, a water intake pipe 4 is fixed with an outlet pipe 5 located above the basin. A heater 6 is installed near the bottom of the tank 3 and, above it, a temperature controller 7. The water outlet pipe 8 is fixed in the bottom of the tank 3 so that its inlet is located directly below the horizontal sealed heat-insulating partition 9 made of rigid foam. The partition 9 divides the cavity of the tank 3 into the upper most part intended for storing cold water, and the lower one, with a volume sufficient for single use, about 4 liters. The water outlet pipe 8 is connected to the inlet fitting of the electric pump 10, the outlet nozzle of which is connected to the pipe 4. Two tubes 11, 12 are fixed in the partition 9. The upper end of the tube 11 is connected to the upper part of the tank cavity, directly above the partition, and the lower end of this tube is placed under the heater. Tube 11 is designed to supply cold water to the bottom of the tank. The tube 12 connects the top of the lower part of the tank with its upper part above the level of filling with water 13. Around the outer surface of the tank, below the partition, an external thermal insulation is fixed 14. The electric pump 10 is connected to the electrical network by means of a limit switch 15, for example, with a foot drive. The capillary tube of the liquid thermostat is tightly wound on the surface of the heating element, protecting the heating element from overheating in the absence of water.

The claimed device operates as follows. Remove the basin from the rack 1, the basin 2, pour clean water into the upper part of the tank 3. Water through the tube 11 fills the lower part of the cavity of the tank, the air from which is removed through the pipe 12. Then add water to the tank 3 to the upper level mark and install the basin 2 in working position. In this case, the basin 2 closes the filling opening of the tank 3. Preparation for work is completed.

To use the washbasin, turn on the power switch (not shown in the drawing) supplying voltage to the electric pump switch and thermostat (not shown in the drawing), by turning the thermostat knob, set the required temperature of the water used, connecting the heater to the mains. After a short period of time (about 4 minutes), the water used is heated to the set temperature, and the thermostat disconnects the heater from the mains. Heated water can be in the washbasin for a long time without heating, since it is isolated from the cold water by a partition, and from external air by external thermal insulation. To maintain the water temperature, the heater is periodically briefly switched on by the temperature controller. To use water, press the foot of the drive of the limit switch 15, including the electric pump 10, which supplies heated water through the pipe 4 to the outlet pipe 5. The electric pump creates a water flow of up to 2 liters per minute, which is enough for comfortable washing. The dosage of the heated water flow is carried out by turning off the limit switch.

In the process of spending heated water, cold water from the upper part of the tank enters through the tube 11 the lower part of the tank, into the zone of the heating element, without mixing with the heated water. Then the water heating cycle is repeated.

In the case of switching on a heating element without water (for example, before the first use of the washbasin), its surface is heated to 120-150 degrees. C, leading to the expansion of the working fluid of the thermostat in the capillary tube wound around the surface of the heater and shutdown. Alternating switching on and off of the heating element does not lead to its failure, and the limitation of its temperature eliminates the fire hazard of the washbasin. In this version, the capillary tube connecting the temperature sensor to the thermostat is itself an additional temperature sensor, but in a different, much higher temperature range. In the presence of water in the tank, a capillary tube wound around the surface of the heater does not practically change the set temperature characteristic of the thermostat.

A prototype of the inventive wash basin was manufactured and tested. Its main characteristics are as follows:

- total tank volume - 14 liters;

- the volume of the lower part of the tank is 4 liters;

- the volume of heated water (above the heating element) - 3 liters;

- installed power of heating elements - 1 kW;

- the heating time of the used water from 15 to 45 degrees. C - 4 minutes;

- network voltage - 220 V;

- washbasin mass (dry) - 6 kg;

- the average power of electricity consumption with long-term maintenance of the temperature of water heated to 45 degrees. With at an ambient temperature of 17 degrees. C, no more - 20 watts.

According to the applicant, the proposed technical solution, having novelty and industrial applicability, can be protected by a patent for a utility model.
