Abstract

The utility model discloses an energy-saving electric heating tube assembly with uniform heating. The energy-saving electric heating tube consists of an electric heating tube (1) and a screw (5). A thermal conductor (2) wraps outside the electric heating tube (1); the shape of the thermal conductor (2) is consistent with that of the electric heating tube (1); the surface of the thermal conductor (2) keeping contact with the bottom of a container is a plane (3); and an annular groove (4) or a plurality of spaced blind holes is/are formed on the plane (3) in the position/positions vertical to the electric heating tube (1) therein. A reflecting plate (6) in a spherical crown shape is fixed on the screw (5) and is separated from the electric heating tube (1) by a distance; a reflecting layer (7) is formed on the surface of the reflecting plate (6) opposite to the electric heating tube (1); the reflecting layer (7) is an infrared ray reflecting coating layer or an electroplated layer; a fixing hole and a threaded hole are formed on the reflecting plate (6); and a porcelain tube (8) is mounted in the threaded hole. Due to no pasty adhesive materials generated on the inner bottom surface, an electric heating instrument assembled with the assembly can be cleaned easily so as to prevent a formica base and a power socket from being damaged by heat radiation. Furthermore, the electric heating tube assembly has the advantages of high thermal efficiency and energy saving.

Description

Uniform energy saving electric heating pipe assembly generates heat

Technical field

The present invention relates to the uniform energy saving electric heating pipe assembly of a kind of heating, especially relate to the be connected as a single entity uniform energy saving electric heating pipe assembly of heating of structure of a kind of electrothermal tube and electric heating vessel bottom surface.

Background technology

Electrothermal tube adopts enclosed construction, so useful life is longer, is widely used in multiple products such as electric food warmer, electric heater.On the product that cheapness is popularized, usually electrothermal tube directly and container bottoms be connected as a single entity, because electrothermal tube and container bottoms contact area are very little, it is thinner to add the electric heating appliance bottom, heating concentrates on the circle, and heat conduction is inhomogeneous, is used for heat milk when cooking, the adhesion that one circle has been stuck with paste, not easy cleaning appear in regular meeting on the bottom surface of internal tank; And influence life-span of electrothermal tube and container.On utensils such as electric rice cooker, adopt the structure of heat-generating disc, promptly, cooperate the thicker the bottom of a pan again at the regular cast aluminium garden dish of shape of electrothermal tube outsourcing, it is reasonable that to have solved above-mentioned heating inhomogeneous and influence the problem in electrothermal tube life-span.But this structure is accompanied by the manufacturing cost problem of higher; And should match with electric heating appliance character, purposes and corresponding construction, not be suitable for all electric heating appliances.In addition, on the electric heating products of cheapness, adopt bakelite material attaching plug, socket and base etc. to match usually with the container of electric heating appliance.Some direct radiation of the heat energy that the ordinary construction electrothermal tube sends not only wastes energy in the supply socket and base of bakelite, also causes supply socket to be heated and to pierce, and the attaching plug that matches with socket also is subjected to thermal radiation and the distortion of generating heat, and damages easily; Radiant heat also causes the wiring copper post in the supply socket loosening, produces poor electric contact.

Summary of the invention

Technical problem to be solved by this invention provides a kind of heating comparatively evenly and the electrothermal tube assembly of energy savings, and cost is low, and reason is overheated and damage yet for the socket of electric heating appliance and base etc. in addition.

In order to solve the problems of the technologies described above, the uniform energy saving electric heating pipe assembly of heating of the present invention is made up of electrothermal tube, screw rod; Electrothermal tube outsourcing one deck heat carrier; The heat carrier shape is agreed to the electrothermal tube shape, and the face that heat carrier contacts with container bottom is the plane; With the vertically opposite position of answering of internal electrical heat pipe a circle groove is arranged on the plane; Fix a reflecting plate on the screw rod; Reflecting plate and electrothermal tube are separated by a distance; Reflecting plate be shaped as spherical crown; On the reflecting plate face relative the reflector is arranged with electrothermal tube.

Reflector on the reflecting plate face relative with electrothermal tube can be the infrared reflecting paint layer of coating.

Reflector on the reflecting plate face relative with electrothermal tube can also be an electrodeposited coating.

Porose at intermediate open position on the reflecting plate, its marginal position has through wires hole, and porcelain tube is housed in the through wires hole.

Can also be circle blind hole at interval on the plane with on the vertically opposite position of answering of internal electrical heat pipe.

Adopt such structure, because electrothermal tube outsourcing heat carrier, the face that heat carrier contacts with container bottom is the plane, on position vertical on this plane with the internal electrical heat pipe, also have a circle groove or a blind hole, under low-cost prerequisite, increased the contact area of electrothermal tube and container bottom, and the position that electrothermal tube and container bottom is nearest separates with groove or blind hole, heat energy is shunted, and has improved the uniformity of heating, and the inner face bottom of electric heating appliance is not easy to produce the adhesion of having stuck with paste, be easy to clean, prolonged the life-span of electrothermal tube and container simultaneously.Reflecting plate and its outermost reflector are collaborative, and the radiant heat energy of electrothermal tube to base reflexed on the container bottom, have improved the heat efficiency, and energy savings has also been protected unlikely raying cause thermal damage such as supply socket and base.
