Abstract
The utility model provides a controllable-temperature heating tube. The structure of the heating tube comprises an inner heating tube which is arranged as an encircling mode and an outer heating tube which surrounds a periphery of the inner heating tube. One end of the inner heating tube is electrically connected with the one end of the outer heating tube through an electric conductor. According to the utility model, the inner and outer heating tubes are arranged as the encircling mode. During usage, according to a usage demand, there are three working states which comprises that only the inner heating tube is used; or only the outer heating tube is used; or the inner heating tube and the outer heating tube are used simultaneously. Different heating power is provided and a purpose that the temperature is controllable is achieved.
Description
Technical field
The utility model relates to the heat-generating pipe technical field.
Background technology
Mostly existing heat-generating pipe is that the various shapes of single heat-generating pipe coiled form, and its power is difficult to regulate.If run into the situation that needs the control heating temp then this kind heat-generating pipe is difficult to reach requirement.Especially the existing heat-generating pipe that is applied to baking oven mostly can only be controlled the break time of whole heat-generating pipe pass and regulate temperature, and result of use is poor.
Summary of the invention
The purpose of this utility model is the heat-generating pipe that proposes a kind of controllable temperature.
According to the heat-generating pipe that the utility model provides, key is to comprise that one end of internal heat generation pipe and outer heat-generating pipe is electrically connected by electric conductor around the internal heat generation pipe of arranging and the outer heat-generating pipe that is looped around internal heat generation pipe periphery.
Heat-generating pipe of the present utility model, by with heat-generating pipe around arranging inside and outside two heat-generating pipes, during use, can select only to use the internal heat generation pipe or only use outer heat-generating pipe or inside and outside heat-generating pipe to use simultaneously three kinds of operating states according to user demand, different heating powers is provided, reaches the purpose of controllable temperature.
Further, described internal heat generation pipe ring can be selected around the number of turns according to the power needs around arranging more than at least two weeks.
Further, the end that described internal heat generation pipe and outer heat-generating pipe are electrically connected is fixed by insulated terminal, and insulated terminal is provided with the conducting strip that connects internal heat generation pipe and outer heat-generating pipe.Insulated terminal plays the effect of inside and outside two heat-generating pipes of support and connection, prevents from only using electric conductor to connect and causes electric conductor to crumble.
Further, internal heat generation pipe and outer heat-generating pipe bottom are provided with out jagged supporting and mounting bracket, and be firm with the overall structure that keeps heat-generating pipe.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are described in further detail.
Embodiment 1:
Such as Fig. 1, heat-generating pipe of the present utility model comprises that around the internal heat generation pipe 1 of arranging and the outer heat-generating pipe 2 that is looped around internal heat generation pipe 1 periphery, an end of internal heat generation pipe 1 and outer heat-generating pipe 2 is electrically connected by electric conductor 3.Internal heat generation pipe 1 can be selected around the number of turns according to the power needs in addition around two weeks.The end that internal heat generation pipe 1 and outer heat-generating pipe 2 is electrically connected is fixing by insulated terminal 4, and insulated terminal 4 is provided with conducting strip 3 electric conductor 3 namely that connects internal heat generation pipe and outer heat-generating pipe.Insulated terminal 4 plays the effect of support and connection internal heat generation pipe 1 and outer heat-generating pipe 2, prevents from only using electric conductor 3 to connect and causes electric conductor 3 to crumble.Internal heat generation pipe 1 and outer heat-generating pipe 2 bottoms are provided with the supporting and mounting bracket 5 that has recess 51 etc., and are firm with the overall structure that keeps heat-generating pipe.During use, an end of alternating current is connected with conducting strip 3, the other end connect 11 21 or with 11,21 connect altogether, just can obtain three kinds of different heating powers, reach the purpose of controllable temperature.
Claims (4)
1. a heat-generating pipe is characterized in that comprising that one end of internal heat generation pipe and outer heat-generating pipe is electrically connected by electric conductor around the internal heat generation pipe of arranging and the outer heat-generating pipe that is looped around internal heat generation pipe periphery.
2. heat-generating pipe according to claim 1 is characterized in that described internal heat generation pipe ring is around arranging more than at least two weeks.
3. heat-generating pipe according to claim 1 is characterized in that an end of described internal heat generation pipe and outer heat-generating pipe electrical connection is fixed by insulated terminal, and insulated terminal is provided with the conducting strip that connects internal heat generation pipe and outer heat-generating pipe.
4. heat-generating pipe according to claim 1 is characterized in that internal heat generation pipe and outer heat-generating pipe bottom is provided with out jagged supporting and mounting bracket.
