Abstract
An electric heater with a hidden heating body includes an electric heater casing (10) comprising a outer casing (11) and an inner casing (12) mounted in the outer casing; an upper grid (13) and a lower grid (14) are arranged at the top and the bottom of the casing (10) respectively; a heating body (15) is mounted on the inner casing or between the inner casing and the outer casing; the space enclosed by the inner casing (12) forms a first airflow convection channel (16); a second convection channel (17) is formed between the outer casing (11) and the inner casing (12); and the casing (10) is supported by a plurality of support feet (18) arranged at the lower part. In the utility model, the two airflow convection channels used for enhancing the heat dissipation effect of the electric heater are arranged, so as to enlarge the heat dissipation area of the electric heater and enable the use to be safer.
Description
[technical field]
The utility model relates to electric heater, particularly relates to a kind of heater and is hidden in electric heater inside, and can strengthen the electric heater with stealthy heater that the electric heater radiating effect is used by the cross-ventilation effect.
[background technology]
The weather in the south and the north differs greatly, and therefore employed heating system is also different.Usually, northern area is by being loaded on the radiator heating in the family, and southern area then uses electric heater to warm oneself.Electric heater on the market can be divided into board-like filling type electric heater (oily spit of fland), pillar filling type electric heater and convection type electric heater now, the hot-air mouth position of existing convection type electric heater is provided with higher, cause the flow range and the area of dissipation of hot blast less, do not have the thermal effect of adding for the position below the human knee, and the narrow dimension of hot-air mouth, cause heat to be concentrated and disperse, the people is touched scald.
[summary of the invention]
The utility model is intended to address the above problem, and provide a kind of heater is hidden electric heater inside, and passes through the air-flow radiating effect that the airflow convection passage strengthens electric heater, and the electric heater with stealthy heater safe in utilization.
For achieving the above object, the utility model provides a kind of electric heater with stealthy heater, it is characterized in that, it comprises the electric heater housing of being made up of shell and cased inner casing, be respectively equipped with grid and following grid in case top and bottom, heater is being housed on the inner casing or between inner casing and the shell, the space that inner casing surrounded forms first airflow convection passage, form second convection channel between shell and the inner casing, housing supports by a plurality of feets of being located at its underpart.
Described inner casing and shell are respectively the rectangular case of lower open mouth, and the shape of described shell is corresponding with the shape of inner casing, and both fits connect, and have the space between the two.
Described heater vertically is fixedly arranged on by screw on the sidewall of inner casing, and this heater heating back forms first airflow convection passage in the space that inner casing surrounded.
Described heater is fixedly arranged between inner casing and the shell, and this heater heating back forms second airflow convection passage between shell and inner casing.
Described heater is electrothermal tube or heating wire.
Described go up grid and down grid be the annular plate-like body, be laid with a plurality of lattice-shaped through holes on its anchor ring, described go up grid and down grid be loaded on the top and the bottom of described fuselage respectively.
Described feet is fixedly arranged on the place, four angles of shell bottom.
Good effect of the present utility model is that it has effectively overcome the hot blast flow range and the area of dissipation smaller defect of existing electric heater.The airflow convection passage that the utility model is used by two radiating effects that are used to strengthen electric heater has strengthened the heating installation area of dissipation, uses safer.

Fig. 1 is an overall structure schematic perspective view of the present utility model.
Fig. 2 is a parts exploded perspective schematic diagram of the present utility model.
[specific embodiment]
The following example is to further explanation of the present utility model and replenishes, the utility model is not constituted any limitation.
As Fig. 1～shown in Figure 2, the electric heater with stealthy heater of the present utility model comprises electric heater housing 10, goes up grid 13, grid 14, heater 15, first convection channel 16, second convection channel 17 and feet 18 down.Wherein, described electric heater housing 10 comprises shell 11 and inner casing 12, and as Fig. 2, described inner casing 12 and shell 11 are the corresponding rectangle housing of going up lower open mouth of shape, and described inner casing 12 and shell are made by metal material, therefore have conduction of heat.Inner casing 12 is an one with shell 12 sockets, has the space between the two.In this example, described heater 15 is an electrothermal tube, and a plurality of electrothermal tubes vertically are fixedly arranged on the relative two side of inner casing by screw.After heater 15 heating, in the space that inner casing 12 is surrounded, form first annular airflow convection passage 16.In another embodiment, described heater 15 also can vertically be fixedly arranged between inner casing and the shell, when this heater 15 heating backs form second convection channel 17 between shell 11 and inner casing 12, thermal current after circulating between shell 11 and the inner casing 12 by on grid 13 send into indoor with following grid 14.Do not disperse because the size broad of electric heater hot-air mouth, the gas of first convection channel 16 can not be concentrated in the process of flowing up or down, therefore be difficult for making the people to touch the back and scald.Grid 13 and following grid 14 outwards dispelled the heat on thermal current not only passed through in cyclic process, and sensible simultaneously shell 11 outwards dispels the heat by heat exchange pattern, therefore hot gas can be passed to the following position of human knee, thereby remedies existing electric heater area of dissipation smaller defect.Described go up grid and down grid 13,14 be the annular plate-like body, be laid with the lattice-shaped through hole 15 of a plurality of heat transmissions on its anchor ring, described go up grid and under grid 13,14 be loaded on the top and the bottom of described fuselage 10 respectively.Described feet 18 is roughly L shaped, and four feets are fixedly arranged on the place, four angles of shell 11 bottoms respectively.
Although the utility model is disclosed by above embodiment, but scope of the present utility model is not limited thereto, do not departing under the condition of the utility model design, more than each member can replace with the similar or equivalent element that affiliated technical field personnel understand.
