Abstract
The utility model discloses a linkage structure of a hollow-core ceramic heating tube and a water supply connector. The linkage structure comprises a heater tube body, the hollow-core ceramic heating tube, a power source L leading wire, a power source N leading wire, the water supply connector, a screw, a big sealing gasket, a small sealing gasket, a heater base, a hot water outlet and a hot water guiding tube. When the water supply connector is connected with water, the water flows through a hollow-core hole of the hollow-core ceramic heating tube. Under the action of water pressure, the water continues to flow through the outer side of the hollow-core ceramic heating tube, reaches an inlet of the hot water guiding tube and then flows toward the hot water outlet of the heater base. After the power source L leading wire and the power source N leading wire of the hollow-core ceramic heating tube are connected with a power source, the hollow-core ceramic heating tube can emit heat, the water takes away the heat in the flowing process, and hot water is generated. By the adoption of the structure, the hollow-core hole of the hollow-core ceramic heating tube is in direct butt joint with the water supply connector, the situation that water temperature is even and not provided with a blind area is guaranteed, and heating efficiency is improved. Besides, the linkage structure is simple in structure, small in size and reliable in use and greatly prolongs the service life of a heater.
Description
Technical field
The utility model relates to a kind of heat exchanger, particularly a kind of heat exchanger of hollow ceramic heating pipe.
Background technology
Along with instantaneous water heater, little kitchen treasured, electric hot water tap are constantly accepted by the consumer, the crux parts of these quick-heating type heaters---the quality of heater directly influences quality and the service life of product.Ceramic heating element since little, the firing rate of thermal inertia soon, can not scaling, long service life, accepted, begin to use by people gradually.But because the ceramic heating element firing rate is fast, from end water inlet, other end water outlet is easy to generate the inhomogeneous and blind area of water temperature, influences performance and the thermal efficiency of its performance.Beat discharge orifice at ceramic heating element on the other hand, in the punching process, be easy to generate stress, can produce fracture in the course of the work, and influence its service life.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, the draw bail of hollow ceramic heating pipe and water supply connector is provided, it not only directly docks with water supply connector in the hollow hole of hollow ceramic heating pipe, 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 draw bail of hollow ceramic heating pipe and water supply connector, hollow ceramic heating pipe is housed in the heater cylindrical shell, one end of hollow ceramic heating pipe has power supply L lead-in wire, power supply N lead-in wire, the other end of heater cylindrical shell is equipped with heater holder, the hot water effluent hole is arranged on the heater holder, water supply connector is screwed at the heater cylindrical shell and compresses big sealing gasket, little sealing gasket, it is characterized in that, dock with the hollow hole of hollow ceramic heating pipe the inlet opening of water supply connector.
Compared with prior art, the beneficial effects of the utility model are: (1) has saved installing space, and water supply connector hollow hole direct and the hollow earthenware connects, and installing space is saved, and flow path is more effective.(2) reliability height, ceramic heating pipe two sides be not to discharge orifice, and the stress that has produced when having avoided punching has reduced the fracture that produces when long-term energising is heated.(3) thermal efficiency height, water enters the arrival other end from hollow one end of ceramic heating pipe, and then arrives the entrance of hot water guiding tube from the outside of ceramic heating pipe, and water flows through the inside and outside surface of ceramic heating pipe like this, has obtained sufficient heating.(4) homogeneous heating non-blind area, the path length of current under the pressure effect of current, has been taken away heated hot water.(5) compact conformation is reasonable.
Description of drawings
Fig. 1 is main pseudosection of the present utility model;
Fig. 2 is structural profile schematic diagram of the present utility model;
Fig. 3 is partial cutaway schematic of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1, Fig. 2, Figure 3 shows that structural representation of the present utility model.
Reference numeral wherein is: heater cylindrical shell 1, hollow ceramic heating pipe 2, power supply L lead-in wire 21, power supply N lead-in wire 22, water supply connector 3, screw 4, big sealing gasket 5, little sealing gasket 6, heater holder 7, hot water effluent hole 8, hot water guiding tube 9.
As Fig. 1, Fig. 2, shown in Figure 3, hollow ceramic heating pipe 2 is housed in the heater cylindrical shell 1, one end of hollow ceramic heating pipe 2 has power supply L lead-in wire 21, power supply N lead-in wire 22, and external power supply is connected on power supply L lead-in wire 21, the power supply N lead-in wire 22, and hollow ceramic heating pipe 2 will the evolution of heat.
Dock with the hollow hole of hollow ceramic heating pipe 2 inlet opening of water supply connector 3, and water enters in the hollow hole of hollow ceramic heating pipe 2 path of form water by the inlet opening of water supply connector 3.
The other end of heater cylindrical shell 1 is equipped with heater holder 7, and hot water effluent hole 8 is arranged on the 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 pipe 2 other end delivery ports have a height difference H, and H 〉=10mm, make current from the outside of hollow ceramic heating pipe 2 the circuitous hot water guiding tube 9 that enters, thereby guarantee water temperature evenly and non-blind area.
After water supply connector 3 connected water, water flow through the hollow hole of hollow ceramic heating pipe 2, and under the effect of water pressure, water continues to flow through the outside of hollow ceramic heating pipe 2, arrived the entrance of hot water guiding tube 9, flowed to the hot water effluent hole 8 of heater holder 7.After the power supply L of hollow ceramic heating pipe 2 lead-in wire 21, power supply N went between 22 external power supplys, hollow ceramic heating pipe 2 will the evolution of heat, and water is taken away heat in process of flowing, just produced hot water.Adopt such structure, not only on the ceramic heating pipe, do not need discharge orifice, guarantee the even non-blind area of water temperature, improve the thermal efficiency, and simple in structure, volume is little, use is reliable, increase the service life of heater greatly.
Most preferred embodiment of the present utility model is illustrated, and various variations or the remodeling made by those of ordinary skills can not break away from scope of the present utility model.
