Description

The utility model relates to household appliances, in particular to immersed water heaters with electric heating elements, and is intended for heating water or other fluid medium.

A household water heater is known, containing a hollow closed body, open at the bottom, the walls of which have channels connected in series with inlet and outlet fittings, the body consists of two shells, one on top of the other, and on the outer surface of the inner shell there are grooves, the walls of which are curved inside the body towards heat flow and form series-connected channels when putting on the outer shell. The inner shell is made of a material with increased heat capacity and thermal conductivity compared to the material of the outer shell, and an additional coil made of a material with increased heat capacity and thermal conductivity, for example, copper, is placed under the upper wall of the housing (patent RU 2133412, IPC F24H 1/12, publ. 20.07. 1999).

This design is quite complex to manufacture and requires materials.

A hot water tank with an immersion heater is known, having a flow channel communicating with the upper and lower parts of the tank and containing a sensor located vertically in the tank to monitor the water temperature. The circulation pump is built into the flow channel to supply water from the bottom to the top of the tank through the heater (patent DE 2950328, IPC F24H1/18, publ. 06/19/1981).

The specified technical solution is not mobile; it refers to a hot water heater with a storage tank, in which a fairly high water level must be maintained.

A submersible water heater is known, in which the rod is surrounded at some distance by a container, which is closed for supplying process water and passes through a hole in the flange. The container around the rod is filled with heating liquid, and its surface protruding into the water tank is at least three times larger than the heating surface of the immersion heater rod (patent DE 3324423, IPC F24H7/02, publ. 01/17/1985).

This design is quite complex to manufacture and operate.

The closest in terms of the set of essential features is a submersible water heater, containing a housing with holes, closed with upper and lower covers, the housing contains a pump and a heating element equipped with a control and regulating device, a heated water outlet pipe with a nozzle, the water heater is equipped with a water level sensor and tilt sensors , sensors and a control device are connected to electronic equipment located in a sealed compartment formed by a partition and an upper cover, which is a control panel and display of the operating status of the device, the pipe is fixed in a fitting with the ability to rotate 360°, and a clamp is located in the upper part of the housing , on which there is a carrying handle, a clip for hanging and C-shaped fixation elements (patent No. RU 215152, IPC F24H 1/20, published 11/30/2022).

The disadvantages of this device are the need for a large volume of water, the complexity of the design, and the presence of additional elements (water level sensor and tilt sensor).

The technical problem to be solved by the proposed technical solution is the creation of a device that provides heating and water intake from the lower level of the main body.

The technical result coincides with the objective and is achieved due to the fact that in a submersible portable water heater containing a main body with holes, with a pump and a heating element with a temperature control sensor housed in it, the main body is equipped with a heated water outlet pipe, a sealed compartment, and a control panel and indicating the operating status of the device, the heating element and the pump are located in the main body in the bottom part vertically and parallelly.

The main body can be cast from polymer. The thermostat can be configured with either temperature control or fixed temperature.

New significant distinctive features of the proposed technical solution are the vertical-parallel location of the heating element and pump in the main body in the bottom part. All this makes it possible to draw heated water from the lower level of the main building. Thus, the use of all essential features allows us to solve the problem and ensure the achievement of a technical result.

The utility model is illustrated by drawings:

Fig. 3 – submersible portable water heater, sealed housing inside, section.

The submersible portable water heater (hereinafter referred to as the water heater) consists of a main body 1, cast from polymer. The main body 1 is made with holes in the form of parallel slots. The holes can also be of any geometric shape, for example, round or rectangular, etc. The purpose of the holes, in addition to filling the main body 1 with water to heat it, is to maximize cooling of the heating element 2 by creating circulation of heated water during its pumping. To ensure assembly of the water heater, the main body 1 is made composite.

In the main body 1 there is a heating element 2 and a pump 3. The heating element 2 and the pump 3 are located in the main body 1 in the bottom part vertically-parallel, thereby providing heating and intake of heated water from the lower level of the main body 1. In some cases, in Depending on the dimensions of the pump 3 used or the layout of the sealed housing 6, the heating element 2 can be installed in the bottom part of the main housing 1.

Adjacent to the heating element 2 is an emergency temperature control sensor 4, which can be manufactured in 2 options: a) have a self-healing mode; b) have a mechanical return to working condition. The main body 1 is equipped with a pipe 5 for discharging heated water, connected to a pump 3. A flexible hose with a watering can with a shut-off valve is connected to the pipe 5, allowing you to turn the water flow on and off. The flexible hose can be equipped with devices for fixing to walls, pipes, taps, etc.

The sealed compartment is made in the form of a sealed housing 6 and is connected to the main body 1. The sealed housing 6 can be connected to the main body 1 both outside and inside the housing 1 and can be made of metal or polymer.

Electromagnetic pump 3 is connected to 220 volts by a wire to a sealed housing 6 and washed with water. Pump 3 is installed with the ability to suck in water from below and drain water upward and starts working immediately when the water heater is connected to the network. Pump 3 is turned off by a built-in thermal fuse if its temperature is higher than the permissible safe values for its operation. Pump 3 is also switched off when the emergency temperature control sensor 4 is triggered.

In the sealed housing 6 there is a thermostat 7, electrically connected to the heating element 2 and equipped with a “START” button 8 for turning on the heating, installed on the upper end of the sealed housing 6, there is also a control panel with a temperature adjustment knob 9 if necessary, setting the thermostat temperature and indicating the status device operation.

Thermostat 7 can be made of 2 types: a) with temperature control from the off state, which approximately corresponds to a value from 0 to 10 degrees to the upper range of 100 degrees; b) a self-switching non-adjustable thermostat with a temperature set by the customer during the manufacturing process. The temperature was set to a constant two-digit number from the range of 35÷70 degrees during its manufacture. When the set temperature is reached, thermostat 7 turns off. Restarting is possible when the temperature is below the set one, using button 8 “START” to turn on the heating.

The principle of operation of the water heater: the water heater is immersed in water. The temperature adjustment knob 9 sets the desired temperature (if there is such a function). The water heater is connected to the network. If there is no heating indication, press button 8 “START”. If the water temperature is less than the set temperature, heating element 2 will switch to heating mode. When the set temperature is reached, heating element 2 will turn off. Restarting the heating mode is possible only by pressing button 8 “START” if the water temperature is 10 degrees less than the set value. If the emergency temperature control sensor 4 is triggered, not only the heating element 2 will turn off, but also the pump 3 with an indication of emergency operation. When the shut-off element located on the flexible hose is opened, heated water is supplied to the user through the watering can.

The submersible portable water heater is industrially applicable and can be manufactured on standard equipment from known materials using modern technologies.
