Description
Technical Field
An electric heating tube combination structure of an electric frying pan belongs to the technical field of electric frying pans.
Background
Electric frying pans have been accepted by more and more people as a common household appliance, but in the prior art, the electric frying pans are different in design quality as a new household appliance. Specifically, the following defects are commonly found in the electric frying pan on the market at present.
The electric heating tube is generally adopted as an electric heating element in the existing household electric frying pan, the electric heating tube comprises a metal tube with openings at two ends, a section of resistance wire for heating is arranged in the metal tube, binding posts are respectively arranged at the openings at two ends of the metal tube and are respectively connected with two ends of the resistance wire, and meanwhile materials with insulation effect and heat conduction effect are filled in the metal tube.
The existing household electric frying pan usually uses two electric heating pipes with the pipe diameter of about 8mm, the two heating pipes are welded on the bottom surface of the electric frying pan after completing the concentric circular arrangement, and the diameters of the circles bent by the two electric heating pipes are respectively 10cm and 21cm, 10cm and 22cm or the combination of 10cm and 24 cm. In the actual use process, a heating pipe bent to be 10cm in diameter and a round pipe bent to be 21cm or 22cm in diameter are sleeved to form a combination, and the pan body with the caliber of 34cm and the pan body with the caliber of 36cm is heated. The heating pipe bent into the diameter of 10cm and the round electric heating pipe bent into the diameter of 24cm are sleeved and combined to heat the pan body with the caliber of 38cm and the caliber of 40cm, which is the only use mode of two electric heating pipes used for heating the electric frying pan in China at present.
The combination of the electric frying pan and the electric frying pan can meet the same requirement that the bottom of the electric frying pan is heated uniformly in the heating process. In order to meet the requirement, the power of the electric heating tube bent into a circle with the diameter of 10cm in the sleeving combination is designed to be between 400w and 500w, the power of the electric heating tube bent into a circle with the diameter of 21cm or 22cm in the sleeving combination is designed to be between 900w and 950w, and the power of the electric heating tube bent into a circle with the diameter of 24cm in the sleeving combination is designed to be between 900w and 1250 w. The three nested and combined electric heating tubes have the following problems in the use process for decades: the electric heating tube bent into a circle with the diameter of 21cm, 22cm and 24cm is easy to be burned out, and great loss is brought to consumers and manufacturers.
The reason for this is that the three sleeves are not designed reasonably, i.e. the current three-combination design has a congenital problem. The design powers of the two heating tubes of the three combinations differ too much. Specifically, the design requirements of the electric frying pan are as follows: the electric frying pan heats the bottom surface of the whole pan body uniformly when in work. The power of the electric heating tube bent into a circle with a diameter of 10cm is usually designed to be 500w, the design power of the heating tube bent into a circle with a diameter of 21cm and 22cm is 950w, and the power of the electric heating tube bent into a circle with a diameter of 24cm is designed to be 1200 w-1250 w, so that the bottom surface of the electric frying pan can be uniformly heated. However, the designed power of the electrothermal tube with the power of 1200w to 1250w already exceeds the power allowed by the normal operation, so the electrothermal tube is easy to be blown. Particularly, when the temperature controller is out of regulation and is still electrified, the heating pipe with high power is easy to blow.
The methods adopted at present for preventing the high-power heating pipe from being blown include the following methods: 1) the resistance wire in the high-power heating tube is thickened, so that the service life of the electric heating tube can be prolonged, but the service life is not long, because the electric heating tube is burnt for a while, but the generated heat can not be transmitted, a heat conducting plate coated on the surface of the electric heating tube is easy to burn out, and then the electric heating tube is burnt out, and in addition, the resistance wire is thickened, so that the pressure resistance of the electric heating tube is reduced, and the technical problem can not be solved by the method; 2) the power of the high-power electric heating tube and the low-power electric heating tube is proportionally reduced to be within the power range allowed by the normal work of the high-power heating tube, so that the power of the low-power electric heating tube is smaller, the power of the whole electric frying pan is too small, the use requirement of a user is difficult to meet, in addition, the length of the low-power heating tube with the too small power is too small, but the smaller the power of the resistance wire is, the larger the resistance requirement is, the longer the length of the resistance wire is, the resistance wire cannot be pulled apart, and the processing is difficult, so the method cannot be used. The two methods are difficult to solve the problem that the electric heating tube is easy to blow under the condition of meeting the requirements of users.
