Abstract

The utility model discloses a high-efficiency insulating water tank of a solar water heater, which has a structure that a water tank shell is formed by an inner liner, an outer insulating layer and a shell; an inlet-outlet pipe, an overflow pipe and a ventilation pipe are led into the water tank; the ventilation pipe is extended into the water tank from the bottom and is higher than the inner pipe orifice of the overflow pipe at the upper end. The utility model can effectively reduce the dissipation of heat of water, improve the insulation effect, improve the working efficiency and the heat collecting efficiency as a solar water heater does, and prolong the annual service life of the solar water heater.

Description

The efficient solar water heater attemperater

Technical field

The utility model relates to a kind of solar water heater, specifically a kind of efficient solar water heater attemperater.

Background technology

Solar water heater water tank is formed tank shell by the thermal insulation layer and the shell of inner bag and outsourcing, and water inlet pipe and water outlet pipe, overflow pipe and scavenge trunk etc. all feed in the tank shell.The scavenge trunk that connects on solar water heater water tank is for water tank being communicated with atmosphere, like this, could successfully carrying out the water filling of solar water heater and the operation that discharges water.And the installation site of the scavenge trunk of existing solar water heater water tank, it is end face at tank shell, it is the top in the tank shell side, its opening all is upwards to be provided with, thereby realize water tank be communicated with atmosphere this-function in, the heat that also has institute's heat accumulation water in the big water-masuring box is discharged outside the case by the scavenge trunk of this upper shed, causes the temperature of solar water heater water tank institute heat accumulation water to descend to some extent.Particularly in colder season, the inside and outside temperature difference of water tank is bigger, and a large amount of of this heat scatter and disappear, and the water temperature that often causes institute's heat accumulation water is crossed low and made the user can not bathing, has shortened the pot life of solar water heater in 1 year thus.

The utility model content

The purpose of this utility model just provides a kind of efficient solar water heater attemperater that overcomes the prior art defective, to reduce scattering and disappearing of water storage heat in the water tank effectively, prolongs the pot life of solar water heater.

The utility model is achieved in that a kind of efficient solar water heater attemperater, thermal insulation layer and shell by inner bag and outsourcing are formed tank shell, water inlet pipe and water outlet pipe, overflow pipe and scavenge trunk feed tank shell, institute's improvements are to be to stretch in the tank shell from water tank bottom with scavenge trunk, and its upper end is higher than the inner spout of overflow pipe.

Key of the present utility model is exactly original upper shed scavenge trunk to be changed become the under shed scavenge trunk.Owing on the overflow pipe inner spout of upper port in water tank of scavenge trunk, so just can make water tank water filling successfully, and when water is full, continue by the overflow pipe overflow; And the lower port setting of scavenge trunk just in time is opposite with the characteristic walked on the hot gas in the water tank, thereby just can significantly reduce by the heat of the water tank inside that this scavenge trunk scattered and disappeared, and has improved the heat insulation effect of water tank thus.And the raising of water tank heat preserving effect also just is equal to the raising of solar water heater operating efficiency and the raising of Heat-collecting effect.The utility model has reduced scattering and disappearing of water storage heat in the water tank effectively, thereby can prolong the pot life of solar water heater.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, this novel heat insulation water tank is formed tank shell by steel shell 3 of the foamed material system thermal insulation layer 2 of stainless steel inner container 1 and outsourcing etc., water inlet pipe and water outlet pipe 4 and overflow pipe 5 etc. feed tank shell, and its basic structure can be identical with the structure of existing solar water heater water tank.Certainly, also electrical heating mouth and/or sewage draining exit can be set correspondingly in the bottom of tank shell.Among Fig. 1, in the cross-under of the bottom of tank shell scavenge trunk 6 is arranged, the top of scavenge trunk 6 is stretched in the tank shell, and its upper end is near the top of inner bag 1 and be higher than about the about 1cm of inner spout of overflow pipe 5.

Overflow pipe 5 in this novel heat insulation water tank can be connected with tank shell with mode by traditional structure, also can with scavenge trunk 6 side by side, stretch in the tank shell from the bottom of water tank, be more convenient for like this installing.The upper port of overflow pipe 5 is generally flat opening, but is preferably the inclined-plane opening.Because overflow pipe of flat opening 5 and scavenge trunk 6, big at hydraulic pressure, on water when fast, having the danger that water filling blocks overflow pipe and scavenge trunk is suitable for reading, inner bag is bursting at the collision because of pressure increases takes place, and the upper shed on inclined-plane, just can solve water filling shutoff problem suitable for reading well, the water tank damage of avoiding so causing.So except overflow pipe 5, the upper port of scavenge trunk 6 also should be made for the form of inclined-plane opening.

The utility model also can be on the basis of above-mentioned various cisten mechanisms, in the outer surface of the inner bag 1 of the tank shell antifreeze thermal isolation film of outsourcing one deck again, with the heat insulation effect of further raising water tank.Antifreeze thermal isolation film can adopt commercially available matured product.
