The relay is arranged on the water inlet pipe, the temperature of the water inlet pipe is basically consistent with the temperature of cold water, and the relay implements heat exchange with the water inlet pipe with cold water flowing therein all the time so as to timely take away heat caused during working of the relay, and therefore, the relay can keep working in proper temperature.

Description

Boilers heated electrically

Technical field

The present invention relates to a kind of heating equipment, specifically a kind of boilers heated electrically.

Background technology

In heating field, boilers heated electrically has safe and reliable, the feature that the thermal efficiency is high, is increasingly widely used in commercial production and resident uses.Boilers heated electrically generally includes cold water inlet, hot water outlet pipe, heating pipe, arranges heating element heater and heating element heater plays the relay composition of control action on heating pipe.

Relay electric component of inside during using can produce heat, such as heat radiation not in time, may result in the damage of relay, thus affects the normal use of boilers heated electrically.In prior art, the heat radiation of relay is typically to arrange fan on relay side, and the setting of fan not only adds installing component, takes up space, and the cold wind that fan provides blows on the surface of relay, and the heat within relay still can not distribute in time.

Summary of the invention

It is an object of the invention to provide a kind of boilers heated electrically, on this boilers heated electrically, the radiating effect of relay is much sooner, effectively.

For realizing object above, the technical solution used in the present invention is: a kind of boilers heated electrically, is connected by heating pipe with outlet pipe including water inlet pipe, and heating pipe is provided with heating element heater, arranges relay on water inlet pipe.

Compared with prior art, there is techniques below effect in the present invention: by arranging relay on water inlet pipe, the body temperature of water inlet pipe is basically identical with cold water temperature, relay is arranged on water inlet pipe, relay implements heat exchange with the water inlet pipe of interior stream cold water all the time, heat when being worked by relay in time is taken away, and makes relay keep working at a suitable temperature.

Detailed description of the invention

Below in conjunction with Fig. 1,2,3, the present invention is described in further detail.

As it is shown in figure 1, a kind of boilers heated electrically, being connected by heating pipe 20 with outlet pipe 30 including water inlet pipe 10, heating pipe 20 is provided with heating element heater 40, arranges relay 50 on water inlet pipe 10.Owing to water inlet pipe 10 has cold water flow and cold water to be continuously replenished entrance all the time, water inlet pipe 10 will remain at lower temperature, relay 50 is arranged on water inlet pipe 10, relay 50 and water inlet pipe 10 remain the contact condition of cold and hot exchange, the heat produced when relay 50 works will be taken away in time, it is achieved that the purpose of cooling relay 50；After the pipeline section of the water inlet pipe 10 that cold water flows through relay 50 arrangement, water temperature will increase, and will at once enter heating pipeline section, and so this heat exchanging process actually also implements heating to cold water, the most necessarily save the energy consumption of subsequent heat.

As it is shown on figure 3, arrange the fixed station 60 made by Heat Conduction Material on described water inlet pipe 10, relay 50 is connected with fixed station 60.The fixed station 60 made by Heat Conduction Material, in that context it may be convenient to relay 50 is fixed and do not affected the transmission of heat.

As it is shown on figure 3, described fixed station 60 is pipeline leakage plugging device, relay 50 abuts on pipeline leakage plugging device.Preferred version is, to being provided with semicircular arc groove on two halfbodies of the pipeline leakage plugging device of the fixed station 60 described in composition, the tube chamber that two arcuate grooves enclose is set on the outer tube wall of water inlet pipe 10.Using such scheme, the fixed station 60 of pipeline leakage plugging device version abuts on water pipe closely, and relay 50 can recline being fixed on fixed station 60 of formula closely, it is ensured that heat is in time, effectively transmit.

As it is shown in figure 1, described water inlet pipe 10 includes the first pipeline section 11 arranged with outlet pipe 30 parallel interval, the two ends of heating pipe 20 are connected with water inlet pipe 10 and outlet pipe 30 respectively and each heating pipe 20 is each other for parallel relationship.Parallel way is used to arrange heating pipe 20, it is possible to reduce the caliber of heating pipe 20 so that water body is uniform, heated fast.

As it is shown in figure 1, the first pipeline section 11 that described water inlet pipe 10 includes and outlet pipe 30 parallel interval is arranged, the second pipeline section 12 being directly linked in sequence with the first pipeline section 11 arranges relay 50.Second pipeline section 12 arranges relay 50 and is because the cold water water pipe preheating through relay 50 place, and at once it is diverted to heating in heating pipe 20 after the water body of preheating timely enters the first pipeline section 11, decreases flowing in pipeline and cause scattering and disappearing of heat.

As shown in Figure 1, first pipeline section 11 and outlet pipe 30 are positioned at horizontal direction, heating pipe 20 between the first pipeline section 11 and outlet pipe 30 is positioned at vertical direction, and the second pipeline section 12 is positioned at vertical direction and coplanar with being positioned at the first pipeline section 11, outlet pipe 30 and heating pipe 20.Water pipe uses such arrangement, and first pipeline section the 11, second pipeline section 12, outlet pipe 30 and heating pipe 20 can be made to be in approximately the same plane, saves space.

As shown in Figure 2, the 3rd pipeline section 13 is connected on the second described pipeline section 12, the 3rd described pipeline section 13 is positioned in same level with outlet pipe 30 and is parallel to each other, and the outside of the same side box wall that the water inlet end of the 3rd described pipeline section 13 extends to boiler tank with the water side of outlet pipe 30 is connected with water supply line and user's pipeline respectively.Such layout makes water inlet and outlet be positioned at homonymy, facilitates pipeline flowing and operation.

As it is shown in figure 1, set gradually temperature sensor, Pressure gauge, air bleeding valve along water (flow) direction on outlet pipe 30.The effect of temperature sensor is to gather leaving water temperature, then temperature signal is sent on central controller, central controller is according to the switch of water body actual temperature regulating relay 50, heating pipe 20 uses the benefit being arranged in parallel to be convenient heating pipe 20 quantity controlling to participate in heating work, and the heating pipe 20 of startup or closedown corresponding position works, the effect reaching to regulate water temperature with this.Pressure gauge is the situation of change of detection water overpressure, such as hypertonia, can be adjusted by air bleeding valve.
