Abstract
A spray/education type hot water and cold water mixer is composed of nozzle, education cavity, mixing chamber, diffusing chamber, cold water jointer, hot water jointer and showering head jointer. Its advantages are no need of valve and movable part and simple structure.
Description
Technical field
The present invention relates to a kind of hot and cold water mixing device, specifically is a kind of apparatus for spray/injecting type mixing cold and hot water.Belong to the mechanical device field.
Background technology
Along with the raising of people's living standard, electric heating miscellaneous, gas water heater have been come into people's family, and people can wash a hot bath at any time easily in the family of oneself, and the personnel that needn't arrive crowd and are subjected in the bathhouse of time restriction.Yet electric heating, gas heater are installed the back and are moved inconvenience, the expensive price of nearly 1,000 yuan has determined it can not generally use in the simple and crude relatively place of some conditions again, resemble the temporary homes such as dormitory, construction site of school, it is uneconomical that the expensive equipment of having a bath is installed, and also is impossible.In these places, from the beginning the suitable water for bathing of temperature that people have to mix sometimes waters down with washbowl, so not only inconvenient, and can cause the huge waste at water source.
Find through literature search prior art, the Chinese patent publication number is the CN87105093A patent of invention, name is called: shower, the shower that this patent is made up of a mixing valve and shower head, by regulating size and the temperature that mixing valve can be regulated current, be a kind of simple and practical shower bath.But this device and electric heating, combustion type bath utensil are the same, and hot water source with pressure must be arranged, and in the place that does not possess the hot water source, can't use.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of apparatus for spray/injecting type mixing cold and hot water is proposed, make it that burned hot water (about 80 ℃) is placed water tank or bucket, use the injection of running water to come the hot water in the injection water tank (bucket) to mix, have a bath for people by the shower head ejection.Realized that simple and easy place staff can easily have a bath.
The present invention is achieved by the following technical solutions, the present invention includes: nozzle, ejection cavity, mixing chamber, diffuser casing, cold water pipe joint, pipe joint of hot water and Connector for shower, its annexation is: at cold water pipe joint one end nozzle is set, nozzle is in injecting chamber, nozzle is made gradual shrinkage, and diameter flows to along cold water and dwindles gradually, when jet expansion, water flow velocity reaches about 22m/s, and the nozzle exit static pressure is approximately than the little 0.3～0.4bar of atmospheric pressure; About the interior diameter of injecting chamber was twice than the overall diameter of nozzle approximately, near coming flow path direction one side to communicate with injecting chamber, the diffuser casing longshore current was to increasing gradually in injecting chamber for pipe joint of hot water, and when exporting, flow velocity reaches 1～2m/s.Injecting chamber, nozzle, mixing chamber, diffuser casing, spray head are taken over and are set gradually along water (flow) direction, and communicate.
Running water sprays from nozzle and quickens, flow velocity at the nozzle place is about 22m/s, cause the pressure of ejection cavity to reduce, be lower than the about 0.3～0.4bar of atmospheric pressure, hot water in the water tank (bucket) is advanced ejection cavity by injection under the atmospheric pressure effect, injection advances the hot water of ejection cavity and the lower running water of temperature that entered by nozzle mixes in mixing chamber, boosts the back from the outlet ejection through diffuser casing again, and outlet can connect to have a bath uses shower nozzle.In the import of nozzle one valve is installed, but the temperature of the size of regulating pondage and water outlet.
The present invention compared with prior art, maximum not being both abandoned and regulated the mixing valve that hot and cold water mixes usefulness, the method that adopts injection to mix, whole device no-movable part, reliable operation.The present invention is simple in structure, and volume is little, and low price is convenient for carrying, and is convenient to move, and the mixing of hot and cold water can be provided preferably, the service of providing convenience and having a bath for the staff in the simple and crude relatively place of condition.

The specific embodiment
As shown in Figure 1, the present invention includes: cold water pipe joint 1, injecting chamber 2, nozzle 3, mixing chamber 4, diffuser casing 5, spray head adapter 6 and pipe joint of hot water 7.Cold water pipe joint 1 one ends are provided with nozzle 3, and nozzle 3 is in injecting chamber 2, and nozzle 3 is made gradual shrinkage, and diameter flows to along cold water and dwindles gradually, and when nozzle 3 outlets, water flow velocity reaches about 22m/s, and nozzle 3 exit static pressures are approximately than the little 0.3～0.4bar of atmospheric pressure; About the interior diameter of injecting chamber 2 was twice than the overall diameter of nozzle 3 approximately, pipe joint of hot water 7, communicated with injecting chamber 2 near coming flow path direction one side in injecting chamber 2, and diffuser casing 5 diameter longshore currents are to increasing gradually, and when exporting, flow velocity reaches 1～2m/s.Injecting chamber 2, nozzle 3, mixing chamber 4, diffuser casing 5, spray head are taken over 6 and are set gradually along water (flow) direction, and communicate.
When the present invention uses, a valve is set before cold water pipe joint 1, is used for regulating discharge, can directly utilize water tap when on running water, using.The pipeline that comes from running water pipe is connected with valve, and valve export is connected with cold water pipe joint 1 by pipeline, and boiler is connected with pipe joint of hot water 7 by flexible pipe, and the present invention's outlet is connected with the bathing shower nozzle by flexible pipe.
Heat water at the Shi Kexian that has a bath to boiler, adjust valve then and make current and water temperature suitable.Boiler can replace with bucket or thermos bottle.
