Specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.It should be appreciated that this place is retouched
The specific embodiment stated is merely to illustrate and explains the present invention, is not limited to the present invention.
In the present invention, in the case of illustrating on the contrary, the noun of locality such as " upper and lower, left and right " of use typically refers to
Upper and lower, left and right shown in refer to the attached drawing；" inside and outside " refers to inside and outside with respect to each part profile of itself.
The present invention provides a kind of electric heater, and wherein, described electric heater includes housing 10 and is arranged in described housing 10
Oil Heater heater 20, has air flow passage between described housing 10 and described oil Heater heater 20, described housing 10
Top be provided with air outlet 11, the bottom of described housing 10 is provided with air inlet 12, and the circulation area of described air inlet 12 is big
Circulation area in described air outlet 11.
Using the electric heater of the present invention, air generation heat exchange and rising of being heated around oil Heater heater 20, lead
Cause there is upper and lower air pressure difference in air flow passage, thus good air stream is formed by air inlet 12 and air outlet 11
Dynamic, namely so that cold air is carried out heat exchange heating in air inlet 12 entrance housing 10 and make heated air from air outlet 11 row
Go out with to surrounding heat supply.This heat-supplying mode is different from common heat loss through radiation, but hot-air is directly discharged into environment
In the air, user gentler by thermal sensation, and heat more rapid.Air-out is less than by the circulation area making air inlet 12
The circulation area of mouth 11, can make air be detained in housing 10 longer time, to obtain more heats, thus the energy when discharging
Enough to around providing more preferable heating properties, ambient temperature is made to increase rapidly.
Wherein, as needed can be with the circulating face of the circulation area of air inlet described in relative set 12 and described air outlet 11
Long-pending, to take into account abundant heat exchange in housing 10 for the air and quick drain with rapid heat supply, thus obtaining good radiating effect.
Preferably, the circulation area of described air inlet 12 and the ratio of the circulation area of described air outlet 11 are 5：4 to 5：3.It is highly preferred that
The circulation area of described air inlet 12 is 10 with the ratio of the circulation area of described air outlet 11：7 to 10：6.1.Arranged by reasonable
The ratio of the circulation area of described air inlet 12 and the circulation area of described air outlet 11, it is possible to obtain more excellent heats.Under
Face illustrates the effect of the preferred embodiment for the present invention by embodiment.
Embodiment
The electric heater of structure as depicted in figs. 1 and 2, the wherein power of oil Heater heater 20 are 2200W, air inlet 12
Sectional area (i.e. circulation area) is n with the ratio of the sectional area (i.e. circulation area) of air outlet 11, air outlet after detection start is stable
11 go out wind velocity v1.
The testing result of embodiment is as shown in table 1.
Table 1
| n | 5：4 | 10：7 | 10：6.5 | 10：6.1 | 5：3 |
