Abstract
The invention discloses a connecting method for a hollow ceramic heating pipe and a water inlet joint. A heater tube body, the hollow ceramic heating pipe, a power supply lead wire L, a power supply lead wire N, a water inlet joint, a screw, a large sealing pad, a small sealing pad, a heater seat, a hot water outlet hole and a hot water guide pipe are adopted. After water is connected into the water inlet joint, the water flows through a hollow hole of the hollow ceramic heating pipe, and under the water pressure effect, the water continuously flows through the outer side of the hollow ceramic heating pipe, reaches an inlet of the hot water guide pipe and flows to the hot water outlet hole of the heater seat. When the power supply lead wire L and the power supply lead wire N of the hollow ceramic heating pipe are externally connected with a power supply, the hollow ceramic heating pipe can give out heat, the water brings away the heat in the flowing process, and the hot water is generated. After the structure is adopted, the hollow hole of the hollow ceramic heating pipe is in direct butt joint with the water inlet joint, the uniform water temperature without a blind region is ensured, the heat efficiency is improved, in addition, the structure is simple, the size is small, the use is reliable, and the service life of the heater is greatly prolonged.
Description
Technical field
The present invention relates to a kind of heat exchanger, particularly a kind of heat exchanger of hollow ceramic heating tube.
Background technology
Along with instantaneous water heater, little kitchen are precious, electric hot water tap is constantly accepted by consumer, the crux parts of these quick-heating type heaters---the quality of heater, directly affects quality and the service life of product.Ceramic heating element because thermal inertia is little, firing rate soon, can not scaling, long service life, gradually by people, accepted, start application.But because ceramic heating element firing rate is fast, from one end water inlet, other end water outlet, easily produce the inhomogeneous and blind area of water temperature, affect performance and the thermal efficiency of its performance.On ceramic heating element, beat on the other hand convection holes, in punching process, easily produce stress, can produce fracture in the course of the work, and affect its service life.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the coupling method of hollow ceramic heating tube and water supply connector is provided, it not only directly docks with water supply connector in the hollow hole of hollow ceramic heating tube, guarantee the even non-blind area of water temperature, improve the thermal efficiency, and simple in structure, volume is little, use is reliable, the life-span of heater increases greatly.
The coupling method of hollow ceramic heating tube and water supply connector, heater cylindrical shell is in-built hollow ceramic heating tube, there are power supply L lead-in wire, power supply N lead-in wire in one end of hollow ceramic heating tube, the other end of heater cylindrical shell is equipped with heater holder, on heater holder, there is hot water effluent hole, water supply connector be screwed at heater cylindrical shell and compress large sealing gasket, little sealing gasket is characterized in that, dock with the hollow hole of hollow ceramic heating tube the inlet opening of water supply connector.
Compared with prior art, the invention has the beneficial effects as follows: (1) has saved installing space, water supply connector hollow hole direct and hollow earthenware connects, and installing space is saved, and flow path is more effective.(2) reliability is high, and ceramic heating tube two sides do not have convection holes, the stress having produced while having avoided punching, the fracture having produced while having reduced long-term energising heating.(3) thermal efficiency is high, and water enters the arrival other end from hollow one end of ceramic heating tube, and then from the outside of ceramic heating tube, arrives the entrance of hot water guiding tube, and water flows through the inside and outside surface of ceramic heating tube like this, has obtained sufficient heating.(4) homogeneous heating non-blind area, the path length of current, under the pressure-acting of current, has taken away the hot water after heating.(5) compact conformation is reasonable.
Accompanying drawing explanation
Fig. 1 is main pseudosection of the present invention;
Fig. 2 is structural profile schematic diagram of the present invention;
Fig. 3 is partial cutaway schematic of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in further detail.
Fig. 1, Fig. 2, Figure 3 shows that structural representation of the present invention.
Reference numeral is wherein: heater cylindrical shell 1, hollow ceramic heating tube 2, power supply L lead-in wire 21, power supply N lead-in wire 22, water supply connector 3, screw 4, large sealing gasket 5, little sealing gasket 6, heater holder 7, hot water effluent hole 8, hot water guiding tube 9.
As shown in Figure 1, Figure 2, Figure 3 shows, heater cylindrical shell 1 is in-built hollow ceramic heating tube 2, there are power supply L lead-in wire 21, power supply N lead-in wire 22 in one end of hollow ceramic heating tube 2, and external power supply is connected on power supply L lead-in wire 21, power supply N lead-in wire 22, and hollow ceramic heating tube 2 will the evolution of heat.
Dock with the hollow hole of hollow ceramic heating tube 2 inlet opening of water supply connector 3, and water enters in the hollow hole of hollow ceramic heating tube 2 by the inlet opening of water supply connector 3, the path of form water.
Water supply connector 3 use screws 4 are fixed on heater cylindrical shell 1 and compress large sealing gasket 5, little sealing gasket 6, make between heater cylindrical shell 1 and hollow ceramic heating tube 2, water supply connector 3 and hollow ceramic heating tube 2 sealing and water-tight.
The other end of heater cylindrical shell 1 is equipped with heater holder 7, has hot water effluent hole 8 on heater holder 7, and hot water guiding tube 9 docks with hot water effluent hole 8, and current enter hot water effluent hole 8 from the entrance of hot water guiding tube 9, have formed the path of water.
The entrance of hot water guiding tube 9 and hollow ceramic heating tube 2 other end delivery ports have a height difference H, and H >=10mm, make current from the roundabout hot water guiding tube 9 that enters in outside of hollow ceramic heating tube 2, thereby guarantee the even and non-blind area of water temperature.
When water supply connector 3 connects after water, water flows through the hollow hole of hollow ceramic heating tube 2, and under the effect of water pressure, water continues to flow through the outside of hollow ceramic heating tube 2, arrives the entrance of hot water guiding tube 9, flows to the hot water effluent hole 8 of heater holder 7.When power supply L lead-in wire 21, the power supply N of hollow ceramic heating tube 2 go between after 22 external power supplys, hollow ceramic heating tube 2 will the evolution of heat, and water is taken away heat in mobile process, has just produced hot water.Adopt such structure, not only on ceramic heating tube, do not need convection holes, guarantee the even non-blind area of water temperature, improve the thermal efficiency, and simple in structure, volume is little, use is reliable, greatly increase the service life of heater.
Most preferred embodiment of the present invention is illustrated, and the various variations of being made by those of ordinary skills or remodeling can not depart from the scope of the present invention.
