Abstract
A quartz heating tube for a micro-wave oven comprises an outer pipe as well as a heating element and connecting parts in the pipe, wherein, the heating element and the connecting parts are made of metal wires; the connecting parts are positioned at two ends of the heating element; elastic telescopic structures are arranged at the connecting parts; the heating element is helicoidal, while each connecting part is approximately linear; the waved or spiral elastic telescopic structures are arranged at the joints of the connecting parts and the heating element, and are formed through bending or winding the metal wires; and the size of the elastic telescopic structure is smaller than that of the heating element, whereas the pitch is larger than that of the heating element. Based on the heating tube of the present micro-wave oven, the elastic telescopic structures are added on the joints of the heating tube, so the extendable space of the heating element is effectively enlarged and the space caused by the heating expansion of the heating wire can be offseted, thereby avoiding the fusing of the heating wire and prolonging the service life of the complete machine.
Description
Technical field
The utility model relates to a kind of microwave oven, specifically is that microwave oven is used quartz heating tube.
Background technology
When the expanded by heating, all heat coils stretch to both sides the microwave current stove with the quartz ampoule heating wire.When not having enough spaces to stretch, will contact between the heating wire coil, cause whole heating wire resistance to reduce easily, because input voltage is constant, so electric current will increase, heating wire produces high temperature, very easily causes heating wire fusing in the coil contact position.Therefore, be necessary to do further improvement.
The utility model content
The purpose of the utility model aims to provide a kind of simplicity of design, and is rational in infrastructure, and the microwave oven of long service life is used quartz heating tube, to overcome weak point of the prior art.
A kind of microwave oven by this purpose design is used quartz heating tube, comprises outer tube and is positioned at the heat generating member and the connecting portion of managing, and heat generating member and connecting portion are processed by wire, and connecting portion is in the heat generating member two ends, and its architectural feature is that connecting portion is provided with the elastic telescopic structure.
Said heat generating member is shape in the shape of a spiral, and connecting portion is shape linearly roughly, is provided with the elastic telescopic structure in the junction of connecting portion and heat generating member.
Described elastic telescopic structure is bent into waveform by wire, or is wound in spirality; And the profile of elastic telescopic structure is less than the profile of heat generating member, or its pitch is greater than the pitch of heat generating member.
The utility model is on the basis of original microwave oven heat-generating pipe; On the connecting portion of heat-generating pipe, increase the elastic telescopic structure, effectively enlarged the extensible space of heat generating member, can offset heating wire because the shared space of heating expansion; Avoid heating wire fusing, prolong complete machine useful life.
Description of drawings
Fig. 1 is the utility model one example structure sketch map.
Fig. 2 is the prior art structural representation.
1 is outer tube among the figure, and 2 is heat generating member, and 3 is connecting portion, and 3.1 is the elastic telescopic structure.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 1, a kind of microwave oven is used quartz heating tube, comprises outer tube 1 and is positioned at the heat generating member 2 and connecting portion 3 of managing; Heat generating member 2 and connecting portion 3 are processed by wire; Heat generating member 2 is shape in the shape of a spiral, and connecting portion 3 is shape linearly roughly, and connecting portion 3 is provided with elastic telescopic structure 3.1 with the junction of heat generating member 2.Elastic telescopic structure 3.1 is bent into waveform by wire, and the profile of elastic telescopic structure 3.1 is less than the profile of heat generating member 2.Elastic telescopic structure 3.1 also can be wound in spirality, and its pitch should be greater than the pitch of heat generating member 2, and screw diameter is less than the screw diameter of heat generating member 2.
Microwave oven heat-generating pipe heating wire is when expanded by heating; All heat coils stretch to both sides connecting portion 3; The elastic telescopic structure 3.1 that connecting portion 3 is provided with has enlarged the extensible space of heat generating member 2; Heating wire fusing is avoided in the shared space of can offsetting heating wire because heating is expanded, and prolongs complete machine useful life.
