Description
Technical field
The present invention relates to storage-type electric water heater, particularly a kind of storage-type electric water heater magnesium rod assembly.
Background technology
Storage-type electric water heater refers to the fixed utensil heated by water, and it for a long time or temporary reservoir hot water, and can be equipped with the device controlling or limit water temperature.Family commonly uses storage-type electric water heater, and it is easy for installation, and price is not high, but need heat the long period, can use after reaching uniform temperature.
Storage-type electric water heater is divided into by its outlet pattern: closed electrical water heater and open type electric water heater two kinds.Closed electrical water heater, and to work by one or more Valve controlling water yield at water outlet under tap water pressure.Such water heater has that installation site is flexible, discharge pressure is high and the advantage such as heat loss is little.But because its inner bag works in situation with pressure, need adopt thicker material, manufacture process requirement is high; The delivery port of open type electric water heater opens wide, by the Valve controlling water yield of on inlet pipeline.This type of water heater works at ambient pressure, therefore the making of its inner bag requires lower, and structure is also relatively simple.At present, the storage-type electric water heater of most of manufacturer production is closed electrical water heater.Storage-type electric water heater is divided into by mounting means: wall hanging is horizontal, wall-mounted vertical and console mode three kinds.When wall hanging horizontal water heater is installed, level is hung on body of wall, is suitable for the water heater that capacity is not more than 100L, has certain requirement of strength to body of wall; Wall-mounted vertical water heater is vertically hung on body of wall when installing, and be suitable for the water heater that capacity is not more than 100L, have certain requirement of strength to body of wall, need be arranged on load bearing wall, non-load bearing wall need install emergency support in advance; Floor hot-water unit can vertically be placed on firm ground when installing, and is suitable for the water heater of more than Large Copacity 100L.
Inner bag is the core component of water heater, directly affects the security performance of water heater, serviceability and working life.User should be concerned about when selecting water heater the material of water heater liner steel plate be whether, welding procedure whether enough thick containing titanium alloy, thickness whether advanced reliable, whether frit for porcelain enamel quality ensures, whether application of slip sintering process advanced.Magnesium is the metal that in electrochemical series, current potential is minimum, nontoxic on physiology.Therefore, be used for making magnesium rod protection inner bag ideal.The size of magnesium rod is directly connected to the length of setting time and the size of protected effect in protection, and magnesium rod is larger, and protected effect is better, and guard time is longer.
At present, storage-type electric water heater magnesium rod is provided with two kinds of modes: one is arranged on heating tube ring flange, and one is arranged on sewage draining exit.When being arranged on heating tube ring flange, difficulty changed by magnesium rod; And close to heating tube, easily form build-up of limescale, affect the heating tube life-span.When being arranged on sewage draining exit, in order to make magnesium rod and inner bag be electrically conducting, blowdown lid needs to use metal material manufacture, and so just make blowdown lid cost high, heat leakage amount is large.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of structure simple, installation and removal are convenient, only simply need transform existing magnesium rod assembly, without the need to increasing new parts, and with low cost and storage-type electric water heater magnesium rod assembly that is that easily realize.
The object of the invention is to be achieved through the following technical solutions: a kind of storage-type electric water heater magnesium rod assembly, comprise magnesium rod, one end of magnesium rod is goed deep in inner bag, the other end of magnesium rod and magnesium rod base close contact, the end face close contact of magnesium rod base and sewage draining exit, sewage draining exit is welded on inner bag, is provided with the dirt-discharging hook mated with sewage draining exit outside sewage draining exit.
Further, described magnesium rod is connected with magnesium rod base by thread: the central axis place of magnesium rod is provided with along its axially extended mandrel, the part that mandrel gives prominence to magnesium rod is provided with external screw thread, the middle part of magnesium rod base is provided with the through hole that mandrel is passed, and is provided with the internal thread matched with the external screw thread of mandrel in this through hole.
Further, described magnesium rod base is located in dirt-discharging hook, is provided with packing ring, is provided with the through hole that mandrel is passed, is provided with the installing hole of fixed central spindle in the middle part of dirt-discharging hook in the middle part of packing ring between magnesium rod base and dirt-discharging hook.
Further, be provided with nut above described magnesium rod base, nut is rotatably mounted on the external screw thread of mandrel.
Further, described magnesium rod base is that metal material is made, and dirt-discharging hook is that engineering plastic materials is made.
The invention has the beneficial effects as follows:
1, magnesium rod and magnesium rod base close contact, magnesium rod base and sewage draining exit end face close contact, sewage draining exit is welded on inner bag, realize magnesium rod and inner bag electrically conducting, structure is simple, and installation and removal are convenient, only simply need transform existing magnesium rod assembly, without the need to increasing new parts, with low cost and easily realize;
2, magnesium rod submount material adopts stainless steel to make, and dirt-discharging hook adopts engineering plastics injection mo(u)ldings, manufactures easy, and its thermal conductivity factor is much smaller than the thermal conductivity factor of metal simultaneously, and heat leakage amount is little, and carrying can the heat-insulating property of high water heater.
