Description
Technical field
The utility model relates to a kind of electric heater technical field, particularly a kind of with have the matching used flexible heating container inlet control device of storage-type electric water heater of flexible inner-tube structure.
Background technology
Existing water heater generally comprises heating container (inner bag), heating tube, temperature controller and relief valve, heating container is rigid container (canister), heating tube and temperature controller stretch into water heating and the thermometric that is respectively in the heating container in the container, relief valve and heating container internal communication, relief valve can be the heating container pressure release.
Be example with the storage-type electric water heater, the water inlet of heating container directly is communicated with running water pipe, running water is toward the interior water filling of heating container, when equating with tap water hydraulic, the heating container internal pressure stops water filling (this moment heating container in water level be at the highest notch or be close to peak), when the water heater heating work, water in the inner bag is heated and expands, the heating container internal pressure raises and heating container is expanded simultaneously, discharge with hot water or discharge by relief valve until pressure, heating container recovers deformation.Architectural feature in view of above-mentioned water heater, make it have following deficiency: (1) is in heating process, the volumetric expansion because water is heated, the heating container water level can surpass the design standard position of establishing 20 ° of C of room temperature originally, when reaching the product design holding temperature, water temperature (surpasses 38 ° more than the C, then water volume can surpass original 20 ° of C ambient temperature position, when water temperature needs higher temperature namely to reach 100 ° of C, part water becomes steam because of high temperature shift, this can make the long-pending rapid expanding of broad object in the heater inside, do not having under the reliable and secure control, then will cause the water heater liner internal pressure to surpass rated pressure, thereby the explosion accident of water heater heating container takes place, bring heavy losses hidden danger to manufacturer and consumer's personal safety; How much hot water when (2) water heater uses and just advance how much cold water, hot water just can come out by cold water pressure, water temperature often occurs and has little time to rise to when temperature required, has had a large amount of cold water to add in the heating container, thus the user when taking a shower water temperature stable inadequately.In sum, existing storage-type electric water heater is not set a reasonably water inlet water level value, when tap water pressure hour, the water level of heating container is then low; When tap water pressure was big, the water level of heating container was full, and the water in the heating container will cause the heating container swell increment to increase after being heated, even exceeded load, had higher security risk; When (3) the heating container internal pressure exceeds setting value, must rely on relief valve discharges pressure, but, existing relief valve is general to be existed because of defectives such as foreign material obstruction or the stuck akinesias of inner body, so, present water heater relies on the relief valve exhaust, will have higher risk of explosion; (4) whether heating tube work be to rely on temperature controller (general setting is when being lower than 5 ℃ of design temperatures in the current water heater industry to heating control circuit with the water temperature feedback information fully, heating tube heats automatically), because temperature controller is arranged in the temperature probing tube, temperature probing tube stretches in the water, so incrustation scale is gathered on the temperature probing tube surface easily, cause thermometric inaccurate (except above-mentioned reason, also might be that temperature controller damages), cause water temperature to be higher than the highest standard of setting, heating container inside is born pressure and is strengthened, when water temperature reaches 100 ℃, produce a large amount of steam, the tiny pressure release passage of relief valve inside also can't in time be discharged steam, finally causes the water heater blast.
