Abstract
An annular ceramic electric heater, the cartridge body is made up of upper cartridge body [2] and lower cartridge body [3], there are grooves to lay the heating element [1] in the cartridge body, the upper cartridge body [2] has radiation holes [8] with the distributed corresponding position of the heating element [1], there are through holes [4] in the middle position of cartridge body, there are concave, convex mouths [7] and [6] to cooperate and mount on the contact surface of the upper cartridge body [2] and lower cartridge body [3] respectively. The structure design is reasonable, the heat is reasonably transmitted and released in a quick and slow mode, the use effect, the heat efficiency and the safety performance are improved, the use cost is reduced, the service life is prolonged, and the electric heating device is suitable for being popularized and applied to household appliances.
Description
Technical field
The utility model relates to a kind of electric heater, particularly a kind of ring-shaped pottery electric heater by ceramic refractory box body sealing and fixing heater.
Background technology
At present, electric heater has been popularized in daily life and has been used, and as directly heating or the household electrical appliance assembly, mainly contains two kinds of bareing and sealed types usually.The heater of bareing electric heater exposes, and directly contacts work adstante febre, easily oxidation, aging with air, heating object (as soup etc.) overflow the contact heating body easily, cause it to damage, its useful life is short, electric shock accidents takes place in poor safety performance easily, jeopardizes personal safety; The sealed type electric heater is mainly used in electric rice cooker, constitutes with the electrothermal tube cast aluminium, though heater does not expose, fail safe is better, but its electrothermal tube insulating barrier also can be leaked electricity the manufacturing process complexity by voltage breakdown, cost is higher, has increased production cost and use cost; The electric heater that also has some other types is also promoted because of its complex structure, high being difficult to of cost.
Summary of the invention
The purpose of this utility model is to provide a kind of improved ring-shaped pottery electric heater for the shortcoming that overcomes above-mentioned prior art, and rationally release heat improves service efficiency, increases the service life energy savings.
The purpose of this utility model can realize by following technical measures: this electric heater has heater, box body, box body is made by ceramic material, box body is made up of upper cartridge body and lower box body, is provided with groove in the box body, and groove is used to lay heater, in heater is wrapped in by box body, upper cartridge body and heater correspondence position are laid with radiating aperture, and radiating aperture is laid at interval along the distribution of heater, aligns heater, direct radiant heat transfer upwards, the power supply wiring of heater from the side direction of box body or the end to drawing; Be provided with through hole at the box body medium position, through hole is communicated with up and down, and preferably circular hole makes lead to the hole site can be used for placing thermostat etc.Box body be shaped as annular.
Be respectively equipped with the concave, convex mouth on the contact-making surface of upper cartridge body and lower box body, install with convenient.
In actual applications, heater is installed in and becomes as a whole in the box body, and when energising was heated, heater carried out radiant heat transfer by radiating aperture, and the while also conducts heat by the upper cartridge body of box body, two kinds of heat transfer type combinations, and anxious delaying mutually helps, upwards the reasonable transmission heat.
Reasonable in design of the present utility model utilizes radiation and conduction heat transfer dual mode in conjunction with heat transfer, anxious slow Ji mutually, reasonable transmission, release heat improve result of use, the heat efficiency and security performance, reduce use cost, the length that increases the service life is suitable for popularization and application on the household electrical appliances.
Description of drawings
Fig. 1 is a longitudinal sectional view of the present utility model.
Embodiment
With reference to Fig. 1, this electric heater has heater [1], box body, box body is made by ceramic material, box body is made up of upper cartridge body [2] and lower box body [3], have through hole [4] at the box body medium position, be used to place thermostat, box body is an annular, upper cartridge body [2] and lower box body [3] also are annular, recessed by on the contact-making surface, tang [7], [6] cooperate installation, recessed, tang [7], [6] be annular, be located at respectively on the contact-making surface of upper cartridge body [2] and lower box body [3] periphery, to make things convenient for upper cartridge body [2] and lower box body [3] location and to install, be provided with circular groove in the upper cartridge body [2], heater [1] is fixed in the groove, and in heater [1] was wrapped in by box body, upper cartridge body [2] was provided with radiating aperture [8] with the correspondence position that heater [1] distributes, radiating aperture [8] distributes regularly along groove location, align heater [1], the diameter of radiating aperture [8] is 3～6 millimeters, the supply terminals [5] of heater [1] from lower box body [3] end to drawing.This electric heater can add loads onto metal case or lid application.
Claims (3)
1, a kind of ring-shaped pottery electric heater, heater [1], box body are arranged, box body is made up of upper cartridge body [2] and lower box body [3], be provided with groove in the box body and lay heater [1], it is characterized in that upper cartridge body [2] and heater [1] correspondence position are laid with radiating aperture [8], radiating aperture [8] is laid at interval along heater [1], is provided with through hole [4] at the box body medium position, and box body is an annular.
