Abstract
The utility model relates to a wall electric heating stove, which comprises a casing, a heating water tank in the casing, a water inlet pipe and a water outlet pipe on the heating water tank, and a control circuit in the casing. The utility model is characterized in that a PTC heating element is arranged in the heating water tank, a water tank which is arranged at the upper part in the casing is connected with the water inlet pipe through a pipeline, and the upper end of the water tank is provided with a nozzle which is communicated with the atmosphere; the heating water tank is arranged at the lower part on one side of the casing. The utility model has the advantages of dry burning resistance, difficult scaling, high heat efficiency and simple structure.
Description
Technical field: the utility model relates to a kind of wall-hanging electric heater, particularly a kind of electric heater with the heat radiation of water heating gas sheet.
Background technology: existing electric heater generally is that a heating water tank is arranged, and electrothermal tube is housed in heating water tank heats, and heated water dispels the heat through radiator.The electric heater of this structure has two serious defectives: 1, can not dry combustion method, if dry combustion method then, cause potential safety hazard at several minutes implosives.2, the thermal efficiency is low, blocks up because the electrothermal tube surface is easy to knot, causes heat conduction bad, causes the thermal efficiency to reduce.The bad shortening that also can cause the electrothermal tube life-span of heat conduction in fact.
The content of invention: the purpose of this utility model is that a kind of dry combustion method of not being afraid of will be provided, and is less scaling, the electric heater that the thermal efficiency is high.
The technical solution of the utility model is that this electric heater comprises shell 1 and inner heating water tank 2 thereof, water inlet pipe 10 on the heating water tank 2 and outlet pipe 4, the control circuit 8 in the housing 1; Be characterized in being equipped with in the heating water tank 2 a PTC heating element heater 3, housing 1 internal upper part has a water tank 5, and water tank 5 is connected with water inlet pipe 10 through pipeline, and there is a mouth of pipe that communicates with atmosphere 6 water tank 5 upper ends; Heating water tank 2 is loaded on the below of a side in the shell 1.
Another characteristics of the present utility model are that a circulating pump 9 is housed on described water inlet pipe 10.
Advantage of the present utility model and effect are: at first be not to be afraid of dry combustion method, that is to say and switch on when not adding water or during the not enough and energising of water level, can not cause the damage of heating element heater and this device.Secondly,, can not enter fluidized state between heating element heater and the medium (water), so be difficult for forming incrustation scale because heating-up temperature is stable and not high at once.So again owing to be difficult for scaling heat and conduct and make thermal efficiency height.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment: as Fig. 1, the outlet pipe 4 of heating water tank 2 connects radiator (radiator) through pipeline, is connected to the water inlet pipe 10 of heating water tank 2 again through return pipe, has filled water (medium) in heating water tank 2, radiator and the connecting pipe thereof.After the energising, PTC heating element heater 3 just heats the water in the heating water tank 2 under the control of control circuit 8.Because heated glassware for drinking water lightens and expands and move upward, so hot water just enters radiator from the upper end of heating water tank 2 behind outlet pipe 4, pipeline, gets back to heating water tank 2 through return pipe and through water inlet pipe 10 again, forms Natural Circulation.Water also is housed in the water tank 5, the one, be used for water in the replenishment cycles system, the 2nd, make circulation line be in passive state (not communicating) because the mouth of pipe 6 of water tank 5 upper ends does not seal with atmosphere.When the needs forced circulation, can open circulating pump 9 circulation rate is accelerated.Also can utilize control circuit to set a temperature, when water temperature reaches this temperature, begin forced circulation automatically.Heating water tank 2 has changed the big capacious design of water tank in the past, uses as far as possible little water bag (water tank) instead and can form the maximum heat coefficient of expansion to cause in the short time, forms thermal cycle in several minutes.We can be set at 80 ℃ with the temperature that starts circulating pump 9, when reaching 80 ℃, water temperature begins forced circulation automatically, make water temperature be controlled at below the boiling point all the time, can reduce the incrustation scale formative factor greatly like this, add that the PTC heating element heater itself has less scaling characteristics, so this wall hanging stove is difficult for producing incrustation scale.This electric heater can mount on wall, to reduce taking of space.
7-is a control panel among Fig. 1.
