Background technology

Water heater is the most frequently used a kind of sanitary bath equipments of people; should gas heater be arranged water heater commonly used at present; electric heater and solar water heater etc. are multiple; the water inlet of these water heaters is connected with the cold water inlet pipe road; cold water is the process combustion gas in water heater; after multiple modes such as electrical heating or absorption solar energy are brought up to suitable high temperature with cold water; for people to use from the delivery port discharge hot water of water heater again; in order to ensure water temperature; usually the temperature of the hot water of discharging in the water heater all is the temperature of having a bath a little more than the best; but; since in some water heaters particularly in gas instantaneous water heater and the electric heater heating process of water be the process of the heating of flowing; therefore; in the use of reality; often be difficult to be adjusted to best water temperature; in the process of bathing through regular meeting the situation that water temperature is too high or water temperature is low excessively appears; cause people in bathing, often need ceaselessly regulate the flow of hot water and cold water, cause the very inconvenience of bathing process.

The reason that causes this situation is that particularly gas instantaneous water heater is in use for water heater, if (this is that the people takes a shower usually just with custom to suspend use hot water midway, also be energy-conservation needs), water in the water heater continues the heat in the extract heat interchanger, because water has stopped flowing in heat exchanger, therefore water temperature can continue to rise, though the time that continues is not long, but water temperature still can raise and make an appointment with the high-temperature region to liquidate 15 ℃ fully mutually in actual use, when if the water temperature that sets is 42 ℃, so this situation hot water can raise and reach about 57 ℃ high-temperature water, and the generally the highest water temperature of accepting of the person is below 48 ℃, exceeding 48 ℃ can make the people feel uncomfortable, even might be arrived by soup, in addition, when after water heater stops, starting once more, flowing to combustion gas from water is lighted and is had one period lag time, whole process need 3-8 second, the heat exchanger cold water that flows through water heater in this time period can not in time obtain heating, cold water can flow out from gondola water faucet or tap, the water of lower temperature can allow the user produce uncomfortable sensation, and therefore serious meeting causes flu etc.

More than two kinds of phenomenons using water heater particularly can often run into during gas instantaneous water heater, people claim that this two kinds of phenomenons are sometimes cold and sometimes hot phenomenon, appearance for fear of this situation, people are when using water heater, just use after painstakingly bleeding off the high and low warm water of this section in the capital, this is not only cumbersome but also can cause water resource waste, particularly for those water heaters install under bathroom situation far away, because water pipe is longer, when often being difficult to correctly hold in use when hot cold phenomenon correct time caused bigger inconvenience with the person at interval.

The utility model content

Technical purpose of the present utility model is in order to address the above problem, exit at water heater is provided with the buffering commuting case with a constant volume, thereby the overheated or cold excessively water that water heater flows out is mixed the constant temperature blender of eliminating the sometimes cold and sometimes hot phenomenon of heat mutually.

For achieving the above object, the hot water outlet place that constant temperature blender of the present utility model is connected in water heater uses, this constant temperature blender comprises the buffering commuting case, hot water input pipe and efferent duct, this hot water input pipe stretches into the interior certain-length of this buffering commuting case and is communicated with this commuting case, this hot water input pipe stretches into the interior pipe section of buffering commuting case as built-in pipe, the spout part of this built-in pipe is provided with the ferrule of sealing baffle with this built-in pipe, effect is not allow water directly flow to outlet downwards, and connect on the tube wall of built-in pipe and be provided with some mixed water holes, allow the water mixing that liquidates fully mutually in the high-temperature region.

Mixed water hole on the tube wall of above-mentioned built-in pipe reduces in the aperture from top to bottom gradually, near the sealing baffle place mixed water hole be not set, so that hot water can fully mix after entering this buffering commuting case by built-in pipe, heat exchange is realized on fullest ground.

Beneficial effect: constant temperature blender of the present utility model, be specifically designed to the buffering commuting case that hot water and cold water are mixed owing to be provided with, therefore in use can store and mix the hot water that flows out in the water heater and cold water, hot water and the cold water regulating and neutralize and from water heater, flow out, make water heater keep comparatively stable water temperature thereby reach through the current of this constant temperature blender output, cold phenomenon when hot when current take place when avoiding bathing, this constant temperature blender can directly design in the water heater the inside, also can be connected between the hot water outlet of the hot water exchanger of water heater and water heater, or be directly connected between the hot water exit of water heater and the gondola water faucet and use, also can be contained in domestic hot water's circulatory system, effect preferably, do not need complicated electronic circuit and complicated accessory in the use, low being convenient to of cost promoted.
