Specific embodiment

When noun of locality "upper", "lower" used in the utility model embodiment are for weighing apparatus formula heater normal use For orientation, the noun of locality "inner" that uses, "outside" are for for this body structure of formula heater that weighs.By taking attached drawing 2 as an example, figure Top in 2 is "upper", lower section is "lower".

" top of outer housing " refers to the structure division by close over of outer housing, has both included the structural portion of surface Point, it also include the structure division of upper side.Similarly, " lower part of outer housing " refers to the structural portion of the close lower section of outer housing Point, both included the structure division of underface, and had also included the structure division of side-lower.

The utility model embodiment provides one kind to weighing apparatus formula heater, referring to Fig. 2, this includes shell to weighing apparatus formula heater Component and it is located at housing unit internal heat generation body 20, housing unit includes outer housing 11 (in conjunction with refering to fig. 1) and inner housing 12, outside Shell 11 forms accommodation space 11a, and heater 20 is installed on the lower part of accommodation space 11a, and inner housing 12 is located at accommodation space In 11a, and between heater 20 and outer housing 11.The lower part of outer housing 11 is formed with air inlet 112a, outer housing 11 Top is formed with exhaust outlet 110a, and exhaust outlet 110a is connected to air inlet 112a；Cold air enters from air inlet 112a to be accommodated In the 11a of space, it is discharged after the heating of heater 20 from exhaust outlet 110a, meanwhile, heater 20 transfers heat to outer housing 11, The air of 11 circumference of outer housing, reaches heating purpose.Further, at least partly covering shell body 11 of inner housing 12 The circumferential direction of inner surface has gap to form air heat-insulation layer between the outer surface of inner housing 12 and the inner surface of outer housing 11. The housing unit of the utility model embodiment, the heat that heater 20 distributes, a part are distributed through exhaust outlet 110a to surrounding In air, another part heat first passes through inner housing 12 and is transferred to outer housing 11 again, and inner housing 12 plays certain heat-insulated effect Fruit reduces the heat that heater 20 is transferred to outer housing 11；Furthermore due to the air between inner housing 12 and outer housing 11 every Thermosphere plays preferable heat insulation, further reduced the heat that heater 20 is transferred to outer housing 11, is effectively reduced The temperature on 11 surface of outer housing, so that outer housing 11 has preferable anti-scald effect.

The shape of inner housing 12 is unlimited, as long as heat insulation can be played.In order to not influence air circulation, interior plate The inner surface of 12a must be smooth surface, avoid the structural mutations rough air such as wedge angle.Further, smooth surface can be curved surface, It is also possible to plane, can also be the combination of plane and curved surface.

Inner housing 12 extends along the short transverse of housing unit, to guide air-flow flowing and as far as possible covering outer panel 114 The more multizone of inner surface.Since the air inlet 112a of air from below enters accommodation space 11a, it is heated after again from top Exhaust outlet 110a discharge, that is to say, that hot-air largely concentrates on the top of accommodation space 11a, causes the top accommodation space 11a Temperature be higher than the temperature of lower part, for this purpose, in the utility model embodiment, the outer surface of the lower part of inner housing 12 and outer housing 11 The distance between inner surface be less than inner housing 12 top outer surface and outer housing 11 the distance between inner surface, so It may make the top of outer housing 11 that there is thicker air heat-insulation layer, further decrease the heat transfer to outer housing 11, so that Temperature difference between the upper and lower part on the surface of outer housing 11 is smaller, promotes the experience sense of user.Further, in order to more preferable Ground guides air flowing, and the bottom end and top of inner housing 12 are tightly connected with outer housing 11, for example, integrally formed sealing is tied Structure, that is to say, that 12 He of inner housing will not be directly entered during air is flowed from air inlet 112a to exhaust outlet 110a In gap between outer housing 11, flow perturbation is avoided.

The shape of inner housing 12 must be matched with the shape of outer housing 11, referring to Fig. 1, in the utility model embodiment, outside Shell 11 is substantially in rectangular parallelepiped structure, including top plate 110, bottom plate 112, relative spacing setting two end plates 113 and it is opposite between Air inlet is formed on bottom plate 112 referring to Fig. 2, being formed with exhaust outlet 110a on top plate 110 every two outer panels 114 of setting 112a, the distance between two end plates 113 are greater than the distance between two outer panels 114.It is understood that exhaust outlet 11a can be with It is formed in the top of outer panel 114, air inlet 112a can be formed in the lower part of outer panel 114.Heater 20 is along outer housing 11 Length direction extend, the distance between heater 20 and two outer panels 114 are smaller, the distance of heater 20 to end plate 113 compared with Greatly, therefore, the temperature on two outer panels, 114 surface is higher than the temperature on 113 surface of two end plates.For this purpose, in the utility model embodiment, The inner surface of two outer panels 114 is covered with inner housing 12, to play preferable heat insulation to outer panel 114.It is understood that It is only inner housing 12 can also to be covered in the inner surface of an outer panel 114, for example, to weighing apparatus formula heater user oriented one The inner surface of the outer panel 114 of side covers inner housing 12.

Above-mentioned gap width can be consecutive variations, be also possible to discontinuous variation.For example, being set when inner housing 12 is tilted When the plate set, which continuously enlarges from bottom to up.In the present embodiment, the variation in gap is that discontinuous variation is specifically asked Referring to Fig.2, inner housing 12 includes transition 121 and equidistant section 123 on the longitudinal section of the short transverse of inner housing 12；Gradual change Section 121 is curve, from the lower part of transition 121 to the top of transition 121, the outer surface of inner housing 12 and corresponding outer housing Gap width between 11 inner surface continuously enlarges；Equidistant section 123 is connected to the lower section of transition 121, under equidistant section 123 Portion to the top of equidistant section 123, the gap width between the outer surface of inner housing 12 and the inner surface of corresponding outer housing 11 are equal. It is understood that equidistant section 123 is also possible to be connected to the top of transition 121, alternatively, the top of transition 121 is under Side is respectively connected with equidistant section 123.

For the ease of the manufacture and installation of inner housing 12, inner housing 12 and outer housing 11 are an integral molding structure, for example, adopting It is squeezed and is integrally formed with aluminum alloy material, alternatively, being integrally formed using plastic material.Further, in order to reinforce inner housing Connection structure intensity between 12 and outer housing 11, please refers to Fig. 2 and Fig. 3, and housing unit further includes being connected to 12 He of inner housing Rib 13 between outer housing 11, i.e. rib 13 are set in gap.

The above, the only preferred embodiment of the utility model, are not intended to limit the protection of the utility model Range.
