Abstract
The invention provides a dry-burning-preventing alarm PTC electric water heater and belongs to the technical field of water heaters. The dry-burning-preventing alarm PTC electric water heater comprises a water heater shell, an inner container, PTC heating rods and a power source. The PTC heating rods are inserted in a cavity of the inner container. The dry-burning-preventing alarm PTC electric water heater is characterized in that a dry-burning-preventing device is arranged and comprises a water level probe arranged at the bottom of the inner container and an electromagnetic valve connected with the water level probe, and the PTC heating rods, the water level probe, the electromagnetic valve, the power source and a power source switch are connected in series. The dry-burning-preventing alarm PTC electric water heater is simple and reasonable in structure, and in the normal work process, a caution lamp is turned on, and the PTC heating rods emit heat; and when the water line in the inner container does not meet the requirement, the caution lamp does not work, and meanwhile the PTC heating rods do not work. The dry-burning-preventing alarm PTC electric water heater is safe, reliable, convenient to use, practical, capable of monitoring the water level and preventing the bad effects caused by dry burning at the same time and wide in market space.
Description
Technical field
The present invention relates to a kind of structure of electric heater, especially a kind of structure of dry heating preventing alarm PTC electric heater, belongs to technical field of water heaters.
Background technology
PTC makes a general reference the very large semi-conducting material of positive temperature coefficient or components and parts, and the PTC that we mention usually refers to semistor, is called for short PTC thermistor.Under PTC normal temperature, impedance is low especially, volume is little, can be widely used in the overcurrent protection of various circuit and electrical equipment, and can install by separated time, protects the safe handling of each circuit to greatest extent, the defect of the integrated protective circuit (IPC) of compensate for over.
PTC is swift in response to overload current, stable and reliable for performance; Impact resistance is strong, long service life; Nonpolarity, alternating current-direct current all can be used; Volume is little, can according to client's needs, the product of the various difformity of processing, specification; Use extensively, can be used for micro machine, motor circuit, stereo set, communication apparatus, instrument and meter, battery component, industrial control system, computer peripheral etc.
Current safety problem is always by people are paid close attention to, and existing PTC device against dry boilding for electric water heater complex structure, poor practicability, is unfavorable for safeguarding.
Summary of the invention
The object of the invention is for above-mentioned the deficiencies in the prior art, the dry heating preventing alarm PTC electric heater providing a kind of structure simple, safe and practical.
The object of the invention is to be achieved through the following technical solutions: a kind of dry heating preventing alarm PTC electric heater, comprise water heater housing, inner bag, PTC heating rod, power supply, described PTC heating rod inserts in inner bag cavity, it is characterized in that, be provided with anti-dry burning device, this device comprises the magnetic valve being placed in water-level detecting head bottom inner bag, being connected with water-level detecting head, and described PTC heating rod, water-level detecting head, magnetic valve, power supply and power switch are connected in series.
Described magnetic valve is normally closed solenoid valve.
Also be provided with warning lamp, this warning lamp and PTC heating rod are connected in parallel, and itself and water-level detecting head, magnetic valve, power supply and power switch are connected in series.
Described PTC heating rod is three, is placed in the upper, middle and lower portion of inner bag cavity respectively.
Described water heater housing is also provided with anion generator.
Described PTC heating rod surface is provided with water barrier.
Described PTC heating rod surface is coated with metal level or ceramic layer, and water barrier is placed in outside metal level or ceramic layer.
Described PTC heating rod is being provided with sealing device with inner bag junction.
The internal heat of PTC heating rod can be transmitted in water by the water barrier in the present invention, can not affect heat transfer; And PTC heating rod and water segregation are opened by water barrier, even if PTC heating rod breaks, water in inner bag also cannot infiltrate and soak the insulating barrier of PTC heating rod, ensure that insulating barrier can not failure of insulation, thus ensure that the electrode slice of PTC heating rod contacts with water in no instance, avoid the generation of electric leakage accident.
The setting of anion generator, negative aeroion, also known as " air vitamin ", it is the indispensable a kind of material of human health life as sunlight, air, the aerial content of anion is the key factor determining air quality quality, in air containing appropriate anion can not only dedusting efficiently, sterilizing, purify air, the oxygen molecule in air can also be activated simultaneously and be formed and take negative oxygen ion.
In the present invention, the top in inner container of electric water heater cavity, middle part, bottom are equipped with PTC heating rod, and this structure is conducive to water homogeneous heating, increase human comfort.
Operation principle of the present invention is: when power switch closes, when the water-level detecting head be positioned at bottom water heater liner detects water level, and solenoid closure, PTC heating rod, warning lamp work; When power switch closes, when water-level detecting head does not detect water level, water-level detecting head sends a signal to normally closed solenoid valve, makes its disconnecting circuit, and meanwhile, PTC heating rod, warning lamp power-off do not work.
The present invention is simple and reasonable, when normally working, and warning lamp light yellow, PTC heating rod heats; When inner bag middle water level line does not reach requirement, warning lamp does not work, and meanwhile, PTC heating rod does not work.The present invention is safe and reliable, simple and practical, can monitor water level simultaneously, prevents the harmful effect that dry combustion method brings, and has the wide market space.
