Abstract

The utility model belongs to hot washing device which can heat running water in a water tap. An existing electric heating shower which can heat running water which passes through adopts a high voltage water switch, the safety and the reliability are low, and a pipe fitting is easily burnt. The utility model adopts a low voltage conductive rubber water switch, which enhances the safety of the device. Simultaneously a drainage hole of the heating cavity of the hot washing device is positioned on the wall of a core pipe at the upper part of the cavity body. A certain high water level can be kept in the cavity all the time. Electrothermal pipes are immersed in water. Water can be thoroughly heated. The phenomenon that because the temperature of the electrothermal pipes is too high, the electrothermal pipes are burnt out can be avoided. After water and power are cut off, the water stored in the cavity can continuously absorb the residual heat of the electrothermal pipes. The service life is extended.

Description

Hot-washing device capable of heating tap water

The utility model belongs to a kind of heat of the hot water tap's of adding flowing water and washes device.

Existing " cross hydro-thermal " electrothermal tube shower adopts 220 volts of water under high pressures to compress switch, and security, reliability are lower, and the electrothermal tube easy burn-out.

The utility model aims to provide a kind of safe and reliable, and the easy burn-out electrothermal tube is not suitable for the various tap heat that need the hot wash-water occasion to use and washes device.

For reaching above-mentioned purpose, the utility model adopts following structure: it includes housing 2, housing 2 internal upper parts can be communicated with the heating chamber 24 of bottom by the intake antrum 23 that joint 1 and faucet outlet join, housing 2 bottoms are provided with delivery port 8, it is characterized in that: the sidewall between intake antrum 23 and the lower heating chamber is provided with low-voltage conductive rubber hydraulic pressure switch K ₂, electrothermal tube 5 is housed in the heating chamber 24, the heating chamber bottom is for what seal, and vertical direction is equipped with a hollow core pipe 6 in the heating chamber, and core pipe top has osculum 25, and the heating chamber bottom that core pipe lower part outlet passes sealing communicates with the delivery port 8 of housing 2 bottoms.Above-mentioned low-voltage conductive rubber hydraulic pressure switch K ₂Being connected on one can connect in the loop of low-voltage relay A coil, the normally open contact of relay A is serially connected in the loop that can connect electrothermal tube 5, and the utility model also is furnished with to relay A to be provided low-voltage dc power supply and the related circuit and the power line of AC power are provided to electrothermal tube 5.

The operation principle of said apparatus is: joint 1 and faucet outlet are linked, power line and power connection, when there not being current out-of-date, low pressure conductive rubber hydraulic pressure switch is an off state, the not conducting of relay A coil, electrothermal tube does not heat yet, and when water was full of cavity and reaches certain flow, low pressure conductive rubber hydraulic pressure switch was connected, the relay normally open contact adhesive, the electrothermal tube energising, to the heating of the water in the heating chamber, heated water flows out through the osculum 25 and the delivery port 8 on core pipe 6 tops.

The utility model adopts the conductive rubber hydraulic pressure switch, has only that current are out-of-date could connect power supply, and the i.e. outage of cutting off the water supply can prevent the dry combustion method phenomenon, particularly owing to employing low-voltage conductive media robber cement compresses switch, so safe and reliable.Simultaneously because the osculum in the heating chamber is provided in a side of the top of vertical core pipe, so can make and remain certain high water level in the heating chamber, make heating tube all be immersed in the water, can fully add hot water, can prevent that again heating tube is exposed to water surface external superheat and burns, after cutting the supply of water and electricity, the water in the heating chamber also can absorb the waste heat of electrothermal tube, has prolonged its service life.This device also has the characteristics that volume is little, cost is low.

Now the utility model is described in further detail in conjunction with the embodiments:

The joint 1 of present embodiment adopts rubber stepped hole joint form, utilizes the larynx hoop to be fixed on the tap so can be easy to land productivity, the delivery port 8 employing porous nozzle formulas of its underpart, thereby can flow out hot water equably.

The conductive rubber hydraulic pressure switch technical parameter of present embodiment is: 6V, 10mA, its concrete structure is seen Fig. 2: have a hole on the sidewall between intake antrum 23 and the heating chamber 24, rubbery membrana dermalis 13 compresses and is positioned at the sealing ring 28 around the hole and is fixed on by screw on the outer wall at cavity perforate position, the gap that is fixed on simultaneously in the outer field printed board 10 of rubbery membrana dermalis between two switches conductive contacts 29,30 faces the conductive rubber contact 12 that is fixed on the rubbery membrana dermalis 13, and keeps certain interval in the horizontal direction with it.When the current in the intake antrum reach when being full of water in certain flow, the heating chamber, because the hydraulic pressure effect, rubbery membrana dermalis promptly can outwards be heaved, and the conductive rubber contact 12 on it is promptly run into two the switches conductive contacts 29,30 in the printed board 10, makes K ₂Closed.
