Description

Submerged electric heaters are widely known. Also known are electrical boiling water devices consisting of a vessel containing a heating device and equipped with a discharge pipe. The proposed device is also immersed in water and also consists of a vessel containing a heating element and provided with a tube for draining heated water; it differs from the known electric heaters in that the rigid vessel is provided with a spring loaded inlet valve for receiving water; By this, automaticity is achieved both in the supply of the device with water and in the discharge of heated water from the device through the tube indicated above.

The proposed device is shown in the drawing in longitudinal section.

In the hard vessel I there is a valve 2 for water inlet, loaded with a spring 3, a damper 4 and an electric heating element 5 with openings for the passage of water. Element 5 is fixed to the end of the tube 7, which serves to drain heated water; the tube 7 is provided with a channel 6 for the wire of the electrical wires to the element 5 and

a hole in the bottom of the dp water intake; tube 7 is also equipped with a crane 8; A flexible hose 9 is fitted on the end of the tube 7 in order to transfer the hot water lifted through the tube 7 to the receiver itself.

The instrument is used as follows. It is immersed in a tank of water that fills the vessel 1 through the opening valve 2. The water in the vessel 1 is heated by element 5, for example, until boiling; due to vaporization, the pressure in vessel 1 rises so much that valve 2 closes and stops communication between the inside of vessel 1 and the water of the above-mentioned reservoir. By the force of the steam pressure, the heated water rises through the tube 7 and through the hose 9 is supplied to the place of discharge. When the vapor pressure decreases due to the consumption of water in the vessel 1, the valve 2 opens with the spring 3; Vessel 1 refills with water and the process repeats. Thus, the automatic transfer of heated water to the receiver of that of the cold water tank in which the proposed device is immersed is carried out.

If it is necessary to heat the water in the indicated tank, turn the flap 4 over and close the opening of the valve 2 with it; at the same time, the second opening in the vessel, which has been closed until then, is opened. If the device is immersed in water, the entire tank is circulated through the second opening. If the latter is closed, then after boiling of the Water located in it, the process of automatic water transfer through hose 9 described above will occur.

The subject matter of the invention.

Claims (2)

1. An electric heater for boiling water, consisting of a vessel that holds electrical to the heating element and is equipped with an f-tube for draining the heated water, its lower end open under the surface of the heated water, which is designed to be immersed in water The rigid vessel 1 is provided with a spring-loaded inlet valve 2 for receiving water, in order to achieve automaticity in both supplying the device with water and discharging heated water from the device through the above-mentioned tube. 2. When using the appliance according to claim 1, use in the vessel 1 of the valve 4, serving to open the second opening in the vessel 1 and to close the opening of the valve 2 in order to use the device to heat the water into which the device is immersed.
