Abstract
The utility model belongs to a temperature regulator of a gas water heater, which is used for eliminating the phenomenon that after a water inlet valve of the water heater is midway closed, a blast of hot water is generated and then a blast of cold water flows out when the water inlet valve is opened again. The utility model is mainly composed of a three-way element, an elastic thin wall bag, and a container with adjustable volume. Cold water is storage into the elastic bag in normal bathing, after the water inlet valve is midway closed, the cold water in the bag is discharged to absorb the heat on an exchanger, and a blast of hot water can not generated. When the water inlet valve is opened again, the cold water firstly flows into the elastic bag, and then flows into the heat exchanger. Thus, a main burner has a period of time to heat the heat exchanger at the start, and consequently, the phenomenon of generate a blast of cold water flows out because of the fast flowing of the cold water can be avoided.
Description
The utility model relates to a kind of gas heater leaving water temperature control set for adjusting.
During shower, the water-flowing gas water heater leaving water temperature generally transfers to 40 to 45 degree Celsius, often in short-term water intaking valve is closed by (as soap time) midway, and then opens water intaking valve.Make the action of aqueous vapor interstage valve though water intaking valve closes to close, cut off source of the gas big fire is extinguished, the heat transfer sheet of heat exchanger, copper plumbing have been burnt to such an extent that have very high-temperature and have been stored certain heat energy.Because water intaking valve is closed, water in the heat exchanger copper plumbing stops going up mobile, heat transfer sheet, copper plumbing store these absorb the heat energy taken away by more flowing water and stop this section water that flows in the copper plumbing and make it become very boiling hot water with regard to having passed to, the water that this section is very boiling hot when opening water intaking valve is once more just squeezed by follow-up cold water and pushes away rapid outflow.Because burning once more of main burner also has little time the leading portion of follow-up cold water is heated to preference temperature when opening water intaking valve once more, thereby after flowing out boiling hot water, can flow out one section cold water again in short-term, flow out suitable warm water again.After measured, to 60 degree, and the temperature of the bigger boiling hot water of this section of gas heater of heating power sometimes even reach more than 70 degree Celsius at 55 degree Celsius for the temperature of the boiling hot water of this section of gas heater that heating power is less.The volume of the boiling hot water of this section is decided by the internal diameter and the length of heat exchanger position copper plumbing, generally about 100 milliliters to 140 milliliters.
It is investigated, when still not having at present gas heater and having solved this water outlet and when hot and ice-cold problem.People adopt the way of dodging usually in the practice, promptly open the water intaking valve forefathers again and leave the water outlet shower head, treat that leaving water temperature returns under the water outlet shower head after suitable.
The purpose of this utility model is to eliminate boiling hot water and the cold water that flows out when opening water intaking valve once more, and leaving water temperature is tended towards stability.
The purpose of this utility model is achieved in that
Behind heat control valve, aperture of serial connection is slightly little than the cold water pipe internal diameter on the cold water pipes before the heat exchanger, apopore axis and the vertical or obtuse-angulate threeway of inlet opening axis water inlet direction, at a port external volume adjustable elastic thin-wall capsule coaxial with the inlet opening, when water intaking valve is opened, because the threeway aperture is less, the cold water flow velocity is accelerated, direct current is in the elastic thin-wall capsule, the pressure of threeway place feed water flow oppose side wall is less even can form negative pressure and (generally do not form negative pressure, should keep minute-pressure zero-pressure at the most), have only low discharge cold water even do not have cold water to flow to heat exchanger.After the elastic thin-wall capsule fills the cold water that storage completely mixes up volume, the cold water that enters threeway all the orifice flow by the threeway sidewall to gas heater heat exchanger copper plumbing.When water intaking valve is closed, when main burner stopped working, the cold water that stores in the elastic thin-wall capsule was flowing to heat exchanger to absorb the heat energy that stores on heat transfer sheet, the copper plumbing and to continue to flow to shower head by the threeway areole under the effect of elastic contractile force.The water water temperature that has stopped flowing in the heat exchanger part copper water pipe when cold water that the interior cool water quantity that stores of elastic thin-wall capsule will be adjusted to storage has been arranged can be raised to the temperature several years (determining the concrete number of degrees by the heating power of concrete season and water heater) that only are lower than suitable bathing.When opening water intaking valve once more, though main burner takes fire immediately, heat transfer sheet, copper plumbing are not raised to very high temperature immediately and need a period of time to heat up, and just have the flowing water of enough heat transferred inside to make flowing water be warmed up to preference temperature then.In the heat transferred pipe of copper plumbing temperature rise period copper plumbing, be lower than the water that stops to flow in suitable bathing temperature several years.Because it is not to enter heat exchanger immediately, in a large number that water intaking valve is opened back cold water, but enter in the elastic thin-wall capsule immediately, in a large number earlier, have only a small amount of even do not have cold water to flow to heat exchanger, along with swelling of elastic thin-wall capsule, hydraulic pressure progressively raises in it, the cold water flow that flows to heat exchanger also progressively increases, when treating to fill again in the elastic thin-wall capsule into cold water, cold water just all flows in the heat exchanger, and heat exchanger heat transfer sheet, copper plumbing temperature also are raised to the degree that can make cold flow water become suitable bathing temperature at this moment.Flowing to heat exchanger cold water flow in this process increases process and adapts with the heat exchanger temperature-rise period, thereby when opening water intaking valve once more, does not just have one boiling hot water outflow, does not also have one cold water to flow out.Concerning the water heater of different brands, model, specification, the cool water quantity that should store is different, but concerning the water heater of a certain concrete brand, model, specification, after the cool water quantity that should store mixes up, under the situation of not changing season, do not need to readjust, therefore can't cause the trouble in the use.Even conversion season, can be positioned on water heater external owing to regulate turn-knob, and regulating also is easily.
On existing gas heater, set up the utility model device, can eliminate one boiling hot water and cold water of producing when opening water intaking valve once more midway, leaving water temperature is tended towards stability.
