Abstract
The utility model relates to an anti-dry burning heater. The purpose of the utility model is to rapidly cut off power and reduce loss when the dry burning occurs. The utility model is composed of a protective cover, an electric heating pipe and a temperature controller, wherein, the temperature controller is positioned in the top end of a metal pipe contacted with the electric heating pipe side by side, the other end of the metal pipe and the leading-out end of an electric heating wire of the electric heating pipe together penetrate through a connecting component to extend into the protective cover, and a power supply connecting wire is led out by the protective cover. The anti-dry burning heater has the advantages of high sensitivity and rapid power cutting-off performance, and can greatly reduce the damage caused by the dry burning.
Description
The utility model belongs to a kind of heater, particularly a kind of anti-dry heater.
Heater is widespread usage in industrial production and people's daily life.When being heated the liquid plane and being lower than heater, if do not cut off the electricity supply, the dry combustion method phenomenon will take place.Dry combustion method not only can cause loss economically, and also can cause personnel's injures and deaths sometimes.Present anti-dry heater, its thermostat is positioned at the guard shield away from the electric heating pipe end, and and electric heating tube between the heat conduction layer of being separated by, the temperature of electric heating tube will could be by the thermostat perception by heat conduction layer, thereby sensitive inadequately, the harm that also just can not avoid dry combustion method fully and brought.
The purpose of this utility model provides the highly sensitive anti-dry heater of a kind of sense temperature, thereby more effectively reduces the harm of dry combustion method.
In order to achieve the above object, adopt following design: the anti-dry heater, form by guard shield, electric heating tube and thermostat, wherein thermostat is positioned at a metal tube top of leaning on mutually side by side with electric heating tube, the heating wire exit of the other end of this metal tube and electric heating tube passes link jointly and stretches the people in guard shield, and power supply wiring is by drawing in the guard shield.
Adopt the heater of such scheme design, because thermostat and electric heating tube be directly adjacent to, thereby the sensing effect is very good, in case generation dry combustion method, heating tube sharply heats up, thermostat can be in the extremely short time perception and with dump, make the loss of dry combustion method drop to minimum.
Be described further below by accompanying drawing.
Fig. 1 is the anti-dry heater schematic diagram that is used for electric heater.
Fig. 2 is the anti-dry heater schematic diagram that is used for solar water heater.
Fig. 3 is the anti-dry heater schematic diagram that not only can be used for electric heater but also can be used for solar water heater.
Embodiment 1: as shown in Figure 1, the anti-dry heater that is used for electric heater by guard shield 1, electric heating tube 2, the metal tube 4 of Kick type temperature controller 3 be housed and form as the ring flange 5 of the band insertion pipe 7 of link.Metal tube 4 one ends are equipped with Kick type temperature controller 3, and the ring flange 5 that the heating wire exit of the other end and electric heating tube 2 passes band insertion pipe 7 jointly extend in the guard shield 1.Metal tube 4 is thick shape pipe gradually, and thin end is positioned at guard shield 1.Metal tube 4 leans on side by side mutually with electric heating tube 2, and is linked to each other by two solder joints, and solder joint not only plays conductive force but also play fixation.Described electric heating tube 2 is a tubular electrothermal element, is shell with the metal tube, and heating alloy is a heater.Fill by heat conducting material magnesium oxide in space in electric heating tube 2 and the metal tube 4.Guard shield 1 is bell, its big opening end and ring flange 5 close proximity, and the osculum end is with rubber sheath 6, and power supply lead wire is drawn from rubber sheath 6.Ring flange 5 with insertion pipe can be inserted in the common water pipe.
Embodiment 2: as shown in Figure 2, be used for the anti-dry heater of solar heater, as different from Example 1, electric heating tube 2 is designed to spiral, to increase heating surface (area) (HS, improves firing rate.This design is convenient to vertically insert in the water tank heat, even have only half chests water (low water level) in the water tank, but also operate as normal.Link is the fixed sleeving 8 that matches with solar water heater, and the bank 9 of a circle projection is arranged between sleeve pipe 8 and the sheath 1, and when this anti-dry heater stretched in the water tank of solar heater, the bank 9 of sleeve pipe 8 was installed on the water tank, and connection mutually coincide.
Embodiment 3: as shown in Figure 3, the anti-dry heater that is used for electric heating or solar water heater, different with example 1 is, ring flange 5 be that the flange screw thread is the nut connector 10 of G3/4, can can be connected with the water tank tight connecting with water, prevent the excessive seepage that causes of hydraulic pressure.
The anti-dry heater that the utility model is related can not only be used for various dissimilar water heaters, thermos is heated up water, and can also be used to heat other media such as oils.
