Abstract
The utility model discloses a volume-type electric water heater, which comprises a heating device, a water storage tank, a water inlet pipe run and a water outlet pipe run. A scavenging valve is installed on a water storage tank; an opening of a water inlet pipe is provided with a check valve and a safety valve. The utility model has the advantages of simple structure and convenient installation. On the basis of the existing electric water heater, the scavenging valve is additionally arranged on the utility model, therefore, a water heater with non-bearing pressure type water out can be carried out; the utility model is advanced equipment at present.
Description
What the utility model related to is a kind of positive displacement electric heater that the pressure-bearing type water outlet also can be implemented the non-bearing type water outlet of both can having implemented.
The electric heater that uses relies on tap water hydraulic to form the pressure-bearing type water-in and water-out at present.The main defect of this water heater is: running water does not have can not use under the situation of pressure, if pressure is less, the water heater water outlet is slower, even can not water outlet; In addition, when the user emitted hot water, cold water entered into water tank from water inlet, and the hot water in the water tank is mixed, and water temperature descends, and the hot water that causes heating can not use fully.
The purpose of this utility model is to provide a kind of working method of carrying out non-bearing type under the prerequisite that does not change original water heater structure, utilizes difference in height water outlet voluntarily, also can implement the water heater of pressure-bearing type water outlet.
The purpose of this utility model is achieved through the following technical solutions, this displacement type water heater comprises heater, water storage tank, check-valves and safety valve are installed on the water inlet pipe mouth of water storage tank, a conduit are set on the air interchanger extend into top in the casing from the water inlet pipe mouth of water storage tank.Conduit also can extend into the top in the casing from the effluent pipe mouth of water storage tank.Air interchanger is provided with scavenging air valve.Scavenging air valve can carry out interlock control with water inlet control valve.Check-valves and safety valve can be arranged to the safety non-return combination valve.
By above technical scheme as can be seen the utility model compare with prior art and have tangible progress.This equipment stretches into conduit top of chamber in the water storage tank from water inlet pipe mouth or effluent pipe mouth under the prerequisite that does not change original water heater structure, realize control by the scavenging air valve on the air interchanger.If have a power failure with when cutting off the water, close inlet valve, open scavenging air valve, implement the non-bearing type water outlet, overcome water heater in the past do not have under the situation of hydraulic pressure can not water outlet defect; The advantage that another one is outstanding is not change the structure of existing electric heater, just can realize non-bearing type water-out manners described in the utility model.
By embodiment integrated structure schematic diagram the utility model is described in further detail.
Fig. 1 is the structural representation that air interchanger described in the utility model feeds from water inlet pipe mouth.
As can be seen, displacement type water heater comprises heater 1 from Fig. 1, and water storage tank 2 is equipped with check-valves 4 and safety valve 5 on the water inlet pipe mouth 3 of water storage tank, a conduit 7 is set on the air interchanger 6 extend into top in the casing from the water inlet pipe mouth 3 of water storage tank 2.Conduit 7 also can extend into the top in the casing from the effluent pipe mouth 8 of water storage tank 2.Air interchanger is provided with scavenging air valve 9, and scavenging air valve 9 can carry out interlock control with water inlet control valve.Check-valves 4 and safety valve 5 can be arranged to the safety non-return combination valve.
