Abstract
The utility model discloses a heat-exchanging water tank of an electric water heater. The heat-exchanging water tank of the electric water heater comprises a water tank and an electric heating device, wherein the electric heating device is installed inside the water tank; a water inlet and a water outlet are formed at the bottom of the water tank; and connecting devices for connecting an external water pipe are connected on the water inlet and the water outlet in a clamping way respectively. The clamping connection structure replaces the conventional threaded connection structure of the water inlet and the water outlet and the external water pipe, so that the problem that the water inlet and the water outlet cannot be separated from the external water pipe due to rusting damage in the using process can be solved; and the heat-exchanging water tank of the electric water heater simplifies the operating process of products, ensures the tightness and the firmness of the water inlet and the water outlet, produces attractive and decent products and greatly improves the qualified rate of the products.
Description
Technical field
The utility model relates to a kind of Teat pump boiler, particularly a kind of electric heater heat exchange water tank.
Background technology
At present, existing electric heater heat exchange water tank generally is made up of water tank and electric heater unit, and electric heater unit is installed in the water tank, offers water inlet, delivery port on the water tank.Yet traditional technological major part all is to adopt the water inlet of long straight tube, delivery port is fixed on water tank through welding manner bottom.In the electric heater installation process; People often are threaded with water inlet, delivery port through external water pipe; In long-term use; The phenomenon that corrosion damages appears in the link position of water inlet and delivery port easily, in case water inlet and delivery port are corroded to a certain degree, then can't realize tight being connected with external water pipe again.At this moment, because the connecting thread of water inlet, delivery port and external water pipe is because of corrosion is bonded together, therefore people have and can't break, and cause the generation of drainage, and electric heater suspends use.And; The water inlet of long straight tube structure, the welding junction of delivery port on water tank are because of welding imprecision, get loose or burning; Cause this product its quality that influences easily again promptly not attractive in appearance, cause the anti-oxidant degree of this product to significantly reduce, thereby yield rate is reduced greatly.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of water inlet and delivery port of effectively preventing to be corroded, to increase work efficiency, to make yield rate to improve and electric heater heat exchange water tank elegant in appearance.
The goal of the invention of the utility model is achieved in that a kind of electric heater heat exchange water tank; Comprise water tank, electric heater unit; Electric heater unit is installed in the water tank; Wherein, water tank bottom is provided with water inlet and delivery port, it is characterized in that: be connected with respectively on said water inlet and the delivery port and be used for the jockey that is connected with external water pipe.
Said jockey comprises welding point, jointing, lock-on connection, and said welding point is connected with water tank, and water inlet pipe and outlet pipe extend to respectively in the inner chamber of welding point.
Said welding point is provided with the boss that is used for tank weld.
Be provided with sealing ring in the said jockey, the sealing snare is between welding point and jointing.
Said jointing outer rim is provided with the chucking platform.
Said electric heater unit is the heater of built-in electric heating plug.
The utility model improves electric heater heat exchange water tank in the prior art; Through changing the water inlet and the delivery port structure of water tank; On water inlet and delivery port, be connected with respectively and be used for the jockey that is connected with external water pipe, replace the water inlet of traditional straight structure of length, the structure that delivery port directly is threaded with external water pipe, thereby avoid the problem that the corrosion damage can't be changed in use occurring because of water inlet, delivery port; Simultaneously; Tightness, the fastness of electric heater unit and water tank connector are guaranteed in this product operation work simplification, make also that product is elegant in appearance and improve the yield rate of this product greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A portion enlarged drawing in the accompanying drawing 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
To shown in Figure 2, the said electric heater heat exchange of the utility model water tank mainly is made up of water tank 2 and electric heater unit 1 according to Fig. 1.Wherein, electric heater unit 1 is installed in the water tank 2, and water tank 2 is provided with water inlet 21 and delivery port 22.Yet; On water tank 2 outer rims, be provided with jockey; On the adaptive respectively and water inlet 21 that is connected in water tank 2 of this jockey and the delivery port 22 and be used for being connected with external water pipe, specifically, this jockey specifically comprises welding point 3, jointing 6, lock-on connection 4 and sealing ring 5.Wherein, Said welding point 3 is provided with the boss of being convenient to water tank 2 welding 31; In concrete operations, this boss 31 is integrated setting with welding point 3, when making welding point 3 with water tank 2 welding through boss 31; Operating procedure is more simplified, thereby increases work efficiency and the welding quality of guaranteeing this product.And, guarantee the attractive in appearance of water tank 2 and welding point 3, avoid not good because of the control intensity of a fire, the outward appearance of infringement water tank 2 and welding point 3 guarantees the antioxygen property of this product, thereby improves the yield rate of this product.Simultaneously, the termination of welding point 3 other ends is connected with the end that jointing 6 is provided with the draw, and water inlet 21 extends to respectively in the inner chamber of welding point 3 with delivery port 22.For the fastness of this product, lock-on connection 4 is tightened on the welding point 3 firmly, thereby jointing 6 and welding point 3 are closely connected.Simultaneously, be connected part through welding point 3 with jointing 6 and be with sealing ring 5, guarantee the tightness of this product.Also have, required according to reality, the other end of the jointing 6 of this product is provided with is convenient to the chucking platform 61 that installs and fixes with external water pipe, help the installation or removal to this product, and the electric heater unit 1 of this product is the heater of built-in electric heating plug.
For this reason; The utility model plug-in structure replaces traditional water inlet 21, the structure that delivery port 22 is threaded with external water pipe; Thereby avoid because of water inlet 21, delivery port 22 in use occur corrosion damage can't with the problem of external water pipe partition, simultaneously, this product operation work simplification; Guarantee water inlet 21, the tightness of delivery port 22, fastness, make also that product is elegant in appearance and improve the yield rate of this product greatly.
