Abstract
The utility model relates to a constant-temperature automatic water mixer. A water mixing tank is equipped with a hot water inlet pipe, one end of a cold water inlet pipe is equipped with an electric control adjusting valve, a water outlet of the electric control adjusting valve is connected with a spray pipe, and the spray pipe is inserted into the water mixing tank; a gyrosphere is arranged inside the water mixing tank, the water outlet of the water mixing tank is equipped with a temperature sensor, a temperature signal transmission line of the temperature sensor is connected with a temperature regulating controller, and a signal control line of the temperature regulating controller is linked with the electric control adjusting valve. As the volume of the water mixing tank is much larger than that of the commonly used three-way water mixing pipe, after mixing the cold and hot water, the mixed water stays longer in the tank body; as the cold water is injected into the water mixing tank, the cold water can be fully mixed with the hot water. In order to reduce the size of the water mixing tank, the gyrosphere is arranged inside the water mixing tank; and by changing the mixed water flow directions for a plurality of times, the hot and cold water are fully mixed.
Description
Technical field
The utility model relates to the mixing arrangement of a kind of cold water and hot water.
Background technology
At present, " click-through " finger-contact type shower water economizer, infrared-sensing type shower water economizer, radio-frequency card shower water economizer widespread usage in the popular bathing pool in various places at home.But the prerequisite of using these products is to adopt the single tube constant temperature water supply.Before cold water and hot water enter the bathroom, just it is mixed into the temperature that is fit to bathing, such as being 40 ℃.Like this, one opens valve, and water temperature is exactly constant, need not the bather and goes to adjust again.
Realize this mixing, can directly water be heated to temperature requiredly, offer bathing pool and use by boiler or heat exchanger.The hot water that also can be ready to sufficient higher temperature in advance exists in the water tank, then injects cold water by artificial in water tank again, changes the ratio of hot and cold water in the water tank, realizes the temperature adjustment, then sends into bathing pool by pipeline.The former advantage is not need storage tank, and floor space is less, and shortcoming is to work as bather number more for a long time, the untimely phenomenon that supplies water may occur, and only is fit to the less bathing pool of scale and adopts.The latter's advantage is to be fit to larger bathing pool, can avoid the under-supply problem of hot water in the bathing process, and shortcoming is not only to need manpower, and is easy to generate water temperature phenomenon fluctuated, and the water-mixing temperature quality is not good.Thereby, need a kind ofly under the situation that does not need manual intervention especially, just can automatically change cold water and hot water ratio as required automatically, cold water, hot water are adjusted into temperature required device automatically.
As far back as 1993, water conservancy project machinery plant in Beijing once released a kind of constant temperature water-water jet.This device is made up of hot water or cold water's source capsule, electric control valve, mixing tube, temperature controller etc.Temperature controller is according to the leaving water temperature height, and the control electric control valve is done left rotation and right rotation, changes to open and close angle, and then changes the flow proportional that enters threeway mixing tube inner cold water and hot water.In this device, when cold water pressure is higher than the heat hydraulic pressure, the warm water that flows out from the warm water delivery port of threeway mixing tube, be hot water to be taken out of by the injection wall attachment effect that cold water produces, because the cavity volume of threeway mixing tube is less, thereby the mixing of cold water and hot water is uneven, so it is stable inadequately to mix water quality, thereby fails to obtain large scale application.
Summary of the invention
According to the defective that existing hot and cold water water admixing device exists, the utility model provides a kind of water-mixing temperature stable, water admixing device easy to use.
Solving the technical scheme that its technical problem adopts is: a kind of constant temperature automatic water-mixing device, and hot water inlet pipe (2) delivery port one end is equipped with non-return valve (4), and non-return valve (4) delivery port connects the hot water inlet (6) that mixes on the water pot (10); Delivery port one end of cold water inlet (1) is equipped with electric control valve (3), at electric control valve (3) delivery port non-return valve (4) is housed, and non-return valve (4) delivery port connects playpipe (13), and playpipe (13) inserts and mixes in the water pot (10); Mix in the water pot (10) gyrosphere (11) is housed, in mixed water pot (10) bottom blowoff valve (12) is housed, mix water pot (10) one ends and be shaped on delivery port (7), temperature sensor (8) is housed on delivery port (7), temperature sensor (8) temperature signal transmission line connects temperature regulation controller (9), and the signal control line on the electric control valve (3) connects temperature regulation controller (9).
One end of playpipe (13) is shaped on spray-hole (14).
Gyrosphere (11) spherome surface is shaped on circular turned hole (15).
The beneficial effects of the utility model are: because the volume of blending tank is much larger than normally used threeway mixing tube, thereby after cold water and hot water mixes in tank body, the time that stops is longer, and cold water enters blending tank with spray regime, thus mix with hot water more abundant; In order to reduce the volume of blending tank, added gyrosphere inside, by repeatedly changing the direction of mixing the back current, make the mixed effect of hot and cold water more abundant.
The utility model is that a kind of water-mixing temperature is stable, water admixing device easy to use.

The specific embodiment
Be described with reference to the accompanying drawings structure of the present utility model.
A kind of constant temperature automatic water-mixing device, as shown in Figure 1, hot water inlet pipe's 2 delivery ports one end is equipped with non-return valve 4, the hot water inlet 6 on the mixed water pot 10 of non-return valve 4 delivery ports connection diameter 100cm; Delivery port one end of cold water inlet 1 is equipped with electric control valve 3, at electric control valve 3 delivery ports non-return valve 4 is housed, non-return valve 4 delivery ports connect playpipe 13, see Fig. 2, playpipe 13 inserts and mixes in the water pot 10, and the end on the playpipe 13 in blending tank 10 has equally distributed spray-hole 14, and nozzle inside diameter is 1～20mm, its quantity can be calculated by the formula more than (caliber/2 ÷ aperture/2), makes the cold water that enters playpipe 13 from spray-hole 14 ejections; The gyrosphere 11 that is used to change the direction of a stream of water is housed in the blending tank 10, sees Fig. 3, water is repeatedly turned back by behind the gyrosphere, changes mixed water (flow) direction, so that cold water hot water fully mixes.Gyrosphere 11 is by light metal or plastic material machine-shaping, and sphere diameter is 100～200mm, is shaped on plural circular turned hole 15 at spherome surface, and the aperture of rotary hole 15 is 5～50mm.In mixed water pot 10 bottoms blowoff valve 12 is housed, mix water pot 10 1 ends and be shaped on delivery port 7, commercially available temperature sensor 8 is housed on delivery port 7, and temperature sensor 8 temperature signal transmission lines connect commercially available temperature regulation controller 9, and the signal control line on the electric control valve 3 connects temperature regulation controller 9.The temperature signal that temperature sensor 8 is gathered is delivered to temperature regulation controller 9; Temperature regulation controller 9 is made left rotation and right rotation according to setting value control electric control valve 3 or is stopped, by changing the size that it opens and closes angle, automatically change the interior cold water of blending tank and the ratio of hot water of entering, thereby obtain and set value the water temperature of basically identical, from the outlet of blending tank 10 through surge tank or directly send into the bathroom or similarly need the occasion of constant temperature water supply.
