Description

A kind of heat-pump water-heater water tank of single-ended assembling
Technical field
The present invention relates to a kind of water-heater water tank, the heat-pump water-heater water tank with rotational moulding layer of especially single-ended assembling.
Background technology
Having relatively high expectations of the sealing device of the heat exchange manifold of heat-pump water-heater water tank requires good seal performance, and water tank is water-tight, good heat insulating with insulate (being used to protect the red copper heat exchanger of heat-pump water-heater water tank not receive electrochemical corrosion).The CN200410014808.1 sealing device relates to the device of this kind structure in the prior art; This invention is used for sticking outlet heat exchanger tube sealing of moulding metal water tank from metal water tank inwall and heat-insulation layer; The heat exchanger exit pipeline directly stretches out water tank wall; Fixed seal head flange plate on the pipeline; At the tank inner wall place fixing one with the nut or the fixed cover of cover flange plane contact, the both sides of cover flange sheet are equipped with the insulation snare, are provided with internal thread nut or cover flange that nut or fixed cover with the cover flange plane contact fix usefulness again in the insulation snare outside in the cover flange outside.Water tank interior conduit of the present invention does not have any joint, so that heat-exchanger pipeline has sufficient intensity to bear the operating pressure of heat pump in the water tank.Good seal performance, water tank is water-tight, and heat resistance is good.But above-mentioned sealing device needs more cover flange structure, and convenient inadequately in installing, and makes things convenient for the slightly careless meeting of process to cause the reliability decrease that seals.
Heat exchanger in the heat-pump water-heater water tank is a helical ring copper pipe shape, also is the most important parts of Teat pump boiler, and heat exchanger is the having relatively high expectations of sealing device of pipeline.CN200320110314.4 has mentioned a kind of cisten mechanism of Teat pump boiler, comprises that metal water tank inwall and heat-insulation layer constitute, and are provided with the metal condensation coil pipe of heat pump in the water tank; Coil pipe is provided with opening at water tank sidewall or end, and condenser coil directly stretches out water tank wall, and condenser coil is provided with the insulation integument at tank inner wall and thermal insulation layer place; Establishing two cover flanges simultaneously is enclosed within on the insulating barrier; Wherein a slice cover flange is welded on the inwall, and another sheet cover flange is screwed onto on the welding cover flange, is provided with sealing O shape circle between two cover flanges; On this O shape snare insulation integument, O shape circle can also be integrated with the insulation integument.Though said structure can bear the operating pressure of heat pump.Outside or interface that the port of heat exchanger stretches out water tank have enough big space on every side, but in general, above structure realizes relatively difficulty of suitability for industrialized production, and the reasonability aspect of structure also needs to improve.
The general inlet and outlet piping of heat exchanger (refrigerant tubing) in the existing heat-pump water-heater water tank advances from an end (bottom) of water tank; The other end (upper end) goes out; Need two end faces to arrange end caps, also just mean and all will carry out the quite high sealing of requirement two end covers up and down; And the signal of also necessary minimum one to two temperature sensor of output of existing heat-pump water-heater water tank, whether control in the hope of work main frame.Sensor export structure on the existing water tank is also reasonable inadequately: the complex structure hermetically-sealed construction is especially like this, also has temperature sensor insensitive, has influence on the temperature control to the main frame temperature.
Summary of the invention
The present invention seeks to, propose a kind of heat-pump water-heater water tank of single-ended assembling.Especially seal and insulate, the work efficiency of assembling is high, and yield rate can obviously guarantee and improve the quality of heat-pump water-heater water tank.The heat exchanger installation quality of water-heater water tank is good, and the heat exchanger in the water-heater water tank is easy for installation with other parts, helps whole sealing property and the service life that promotes water-heater water tank.
The present invention seeks to realize like this: the heat-pump water-heater water tank of single-ended assembling; Comprise inner water tank, heat exchanger, heat-insulation layer and shell; Heat exchanger is inner at inner water tank, and the inner water tank inner surface has the rotational moulding layer, and the inner water tank skin is provided with the heat-insulation layer and the shell of foaming; The upper end welding integral end socket of inner water tank; End socket is provided with hot water out pipe; Welding cover flange in the lower end of inner water tank is also installed sealing gasket and end cap on cover flange, end cap seals through sealing gasket and cover flange, and end cap is provided with the outlet that inlet opening and water tank heat exchanger are drawn out pipe; Heat exchanger is the spiral endless tube that copper pipe turns to same diameter, and pipe is directly drawn out in the lower end of spiral endless tube under the end cap lower direction, and the upper end bending of spiral endless tube is drawn out pipe downwards and from the end cap below in spiral coil.
The spiral endless tube be solid matter and to constitute integral body be cylindrical.Also can be how much cylindricalitys such as elliptical cylinder-shape, square cylindricality.
The sealing device structure of pipe on end cap of drawing out of the heat exchanger helical endless tube of water-heater water tank is to comprise nut 22, silica gel circle 23, supports insulative pad 24, rotational moulding layer 25, A/C 26, screw thread 27; A/C is fixed on the outlet opening of end cap, and the said pipe of drawing out stretches out from said outlet opening that is fixed on and A/C, and A/C is provided with step and is provided with the rotational moulding layer in the oral area inboard of near-thermal water heater tank inner container; Heat exchanger is drawn out and is with supports insulative pad and silica gel sealing ring 23 on the pipe, ends the threaded outer wall that the nut 22 that encloses is spun on A/C 26 with band again, the step that the outside of supports insulative pad is provided with and A/C oral area inner side step is coincide.
The height of supports insulative pad and silica gel sealing ring 23 is a little more than the height of A/C, heat exchange manifold insulated the distortion of insulation spacer and silica gel sealing ring 23 in the outlet opening sealing of water-heater water tank and with the metal level of water tank when then the band nut 22 that ends circle is tightened the threaded outer wall that is spun on A/C 26.
Inner bag is a cylindrical structure.Water inlet or delivery port be through a threeway, and one on the both sides of threeway output are taken the joint at the mouth of a river out of for circular arc, and one is circular arc band loose joint version.
Overlap second a supports insulative pad that internal diameter is identical on the silica gel circle 23 again; The outside of the second supports insulative pad is provided with and only encloses the step that step matches with the nut 22 that ends circle, this two can be structure as a whole.
