Abstract
The utility model discloses a constant pressure water storage electric water heater, comprises a water storage tank, a heat preserved layer and an electric heating tube. The utility model is characterized in a three-port adjust valve is positioned on a cool water input pipe, one end of the three-port adjust valve is connected to the cool water input pipe, one end is connected to the one-way valve leading to the input pipe of the storage water tank, the other end via the cool water output pipe and the three-port is connected to the heat water output pipe, a jet device is positioned on a heat and cool water mixed pipe of the three-port, the jet device is vertical to the outlet and connected with a spout, the side outlet of the jet device is connected with the overflow pipe, an overflow pipe one-way valve is positioned on the overflow pipe. The utility model uses a simple structure to solve the problem of water storage electric water heater with voltage, not only greatly improves the operation safety, but also decreases the pressure bearing requirement of the tank and pipe under the constant pressure, and saves some parts and decreases the cost.
Description
Technical field
The utility model relates to electric heater, particularly a kind of normal pressure storage-type electric water heater.
Background technology
At present, the operation principle of known electric heater is: water is directly added in the water tank that heat-insulation layer is arranged of water heater, through electric heater the heating of the water in water tank back is prepared against and used.Cold water pipe is to the water tank moisturizing during use, and hot water is forced out for using.But, in case after closing hot water outlet, because the water in water tank continues to be heated steam is expanded, so the inner bag of water tank need bear certain pressure, the material of making inner bag all there is being higher requirement aspect intensity and the thickness, and safety valve need be set on water tank.In a single day existing storage-type electric water heater takes place that pressure regulator is malfunctioning, dirt stops up or automatically controlled malfunctioning, all might cause blast, brings harm for people's lives and properties.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of normal pressure storage-type electric water heater simple in structure, safe, easy to use is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of normal pressure storage-type electric water heater, comprise water tank, heat-insulation layer and electrothermal tube, it is characterized in that: be provided with threeway at cold water inlet pipe place and regulate water valve, the end that water valve is regulated in described threeway connects cold water inlet pipe, one end connects the check valve that leads to the water tank water inlet pipe, one end is connected with hot outlet pipe with threeway by cold outlet pipe, the cold and hot mixed conduit of described threeway is provided with ejector, the ejector vertical outlet is connected with shower nozzle, the outlet of ejector side is connected with overflow pipe, and overflow pipe is provided with the overflow pipe check valve.
Because the utility model has been taked above-mentioned technical measures, it has compared with prior art solved storage-type electric water heater problem with pressure with simple structure, not only the security of Shi Yonging improves greatly, and owing to be under normal pressure, to work, tank body, pipeline bearing requirements are reduced, and saved subelement, reduced cost.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
With reference to accompanying drawing, the utility model is identical with existing storage-type electric water heater at the water storage heating part, comprises water tank 1, heat-insulation layer 2 and electrothermal tube 3.Blow-off pipe 4 is arranged on the water tank 1.Be provided with threeway at cold water inlet pipe 7 places and regulate water valve 6, the end that water valve 6 is regulated in threeway connects cold water inlet pipe 7, one ends and connects check valve 5, one ends that lead to water tank water inlet pipe 8 and be connected with hot outlet pipe 11 with threeway 10 by cold outlet pipe 9.The cold and hot mixed conduit 16 of threeway 10 is provided with ejector 14, and ejector vertical outlet 17 is connected with shower nozzle 15, and ejector side outlet 18 is connected with overflow pipe 12, and overflow pipe 12 is provided with overflow pipe check valve 13.Operation principle of the present utility model is: under the condition that realizes temperature adjustment, key is to avoid turn-offing the steam expansion that the hot water vapor path produces, and is in atmospheric pressure state to guarantee storage-type electric water heater.Cold water is regulated water valve 6 by threeway and is divided into two-way.One the tunnel is used for mixing with hot water outlet, a road direction water tank 1 moisturizing, and hot water is forced out.As the water yield that enters water tank 1 is when advancing the water yield of mixing water, and hot water yield strengthens, and cold mixing water reduces, and leaving water temperature rises; Otherwise water temperature descends, to reach the purpose of temperature adjustment.When cold and hot mixed flow during through ejector 14, can make overflow pipe 12 produce negative pressure, overflow pipe check valve 13 is closed, cold air can not enter cold and hot mixing water, in order to avoid influence the temperature and the flow of water.Cold and hot mixing water flows out for using by shower nozzle 15.When stopping using, close threeway adjusting water valve 6 back shower nozzles 15 and stop water outlet.But steam can expand when continuing heating owing to the water in water tank 1, and at this moment because overflow pipe 12 does not have negative pressure, and overflow pipe check valve 13 is in open mode, a little expansion steam enters sewer from overflow pipe 12 by overflow pipe check valve 13.Because storage-type electric water heater communicates with atmosphere, so be in atmospheric pressure state all the time.It is to adjust by two water flow allocation proportions of 6 pairs of cold water inlets of threeway adjusting water valve to reach that the utility model adjusts coolant-temperature gage.Ejector 14 with make that cold air can not enter in the mixing water when the water cooperating of overflow pipe check valve 13, in order to avoid influence water temperature and discharge, but when stopping using, a small amount of steam in the storage-type electric water heater can be discharged again and guarantee normal pressure, be unlikely to again shower nozzle is leaked.
