Description

Electric heating device

Technical field

The utility model relates to a kind of technical field of electrothermal warmer.

Background technology

Along with improving constantly of people's living standard, the electrothermal warmer has advantages such as convenience, economy, quick heating, environmental protection because of it, in modern resident family, obtain large-scale popularization and use, especially for use in as in the bathroom, places such as bedroom or toilet.The general structure of existing electrothermal warmer is: have a casing, have into and out of the air port on the casing or louvre, electrothermal tube, temperature controller and power switch etc. are housed, as disclosed in the Chinese patent 98220867.7 " multi-function electric air heater " in the casing.Its defective is: temperature controller, power switch and relevant connection expose to the open air in chassis cavity with electrical equipments such as electric wires, because of directly being subjected to the heat radiation of electrothermal tube, easily aging and influence service life, especially when warmer is used for the bathroom heating, because of general humidity in the bathroom is very big, makes above-mentioned components aging even electric leakage and influence the safe handling of warmer easilier.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of long service life and safe and reliable electrothermal warmer at above-mentioned prior art present situation.

The utility model is to solve the problems of the technologies described above the technical scheme of being taked to be: this kind electric heating device, it comprises the casing casing, have air inlet and air outlet on the casing casing, in the casing casing heater is housed, it is characterized in that being equipped with on the casing casing control box of dress electric controling element in being used for.

Described electric controling element comprises temperature controller and power switch.

Described air inlet is located at the bottom of casing casing, and described air outlet is located at the top of casing casing.The bottom that air inlet is located at the casing casing helps the convection current of air on the one hand, can prevent that on the other hand sealing is splashed in the casing.

The other temperature limiter that is provided with of described heater, temperature limiter can reach the purpose of safeguard protection at heater because of accidental abnormal operating state temperature cuts off the electricity supply temperature controller when too high automatically.

Described heater is the electrothermal tube that has radiating fin, has radiating fin and is convenient to venting box increase heat exchange area.Certainly, heater can also save fin with the fixing flat resistance silk structure of mica sheet.

Compared with prior art, advantage of the present utility model is: because of having increased the control box structure, can prevent effectively that electrical equipment except that heater is subjected to the erosion of direct heat radiation and possible superheated vapor, thereby slowed down its ageing process, prolong the service life of warmer, also improved the safety in utilization of warmer simultaneously; In addition, because of the mode of the free convection of air to the room heating service passed through in employing, so the basic noiselessness of the utility model.

Specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1～shown in Figure 5, be a preferred embodiment of the present utility model.As Fig. 1～shown in Figure 3, the described electric heating device of present embodiment is vertical setting, and it has the casing casing, the casing casing is made of panel 1 and back shroud 2, the top of panel 1 is provided with air outlet 3, and movable rack 4 is housed in the air outlet 3, and the bottom of back shroud 2 is provided with air inlet 5.As shown in Figure 4, the heater that is made of the electrothermal tube 7 of being with radiating fin 6 is equipped with in the bottom of casing cabinets cavity, and control box 8 is equipped with on the top of casing cabinets cavity.As shown in Figure 5, in the control box 8 electric controling element being housed---power switch 9 and temperature controller 10, in addition, power line 18 is also drawn from control box 8, also is provided with earthing screw 19 on the control box 8.Temperature controller 10 can be provided with needed temperature easily by the knob on it 11, has air vent 12 on the box body of control box 8, has both helped heat radiation, can make sensing chip institute sensed temperature on the temperature controller 10 near indoor temperature again.During use, the air inlet 5 of cold air slave housing box body bottom enters the casing casing, after the heater heating, under the effect of the negative pressure that in the casing casing, produces, naturally rise along the air channel that the casing casing forms, the air outlet 3 of last slave housing box body top tool grid 4 is discharged, and the free convection by air is to the room heating service.Cold air constantly is heated the back discharge like this, and indoor temperature constantly raises, and when indoor temperature reached by temperature controller 10 predefined temperature, temperature controller 10 was cut off the electricity supply; And when indoor temperature dropped to certain value, temperature controller 10 was connected power supply again automatically and is made electrothermal tube 7 work, made like this that the room is constant to be maintained in the temperature range that sets.In addition, also be provided with a temperature limiter 13 in that electrothermal tube 7 is other, temperature limiter 13 can reach the purpose (referring to Fig. 4) of safeguard protection at heater because of accidental abnormal operating state temperature cuts off the electricity supply temperature controller 10 when too high automatically; And can operate as normal after fault is got rid of the time, temperature controller 10 promptly automatically resets, and warmer recovers operate as normal again.

As shown in Figure 1, the air outlet 3 on panel 1 top is equipped with grid 4, and it can play decoration function again when hot-air can be discharged smoothly, can prevent that also water droplet directly is splashed in the casing casing.A few frame grizzly bars are fixed on (not shown) on the same interlinked mechanism, thereby can regulate the direction of the angle change hot blast discharge of grid bar by interlinked mechanism.

As shown in Figure 4, the electrothermal tube 7 of band radiating fin 6 is installed in the bottom of casing cabinets cavity by support 14, when electrothermal tube 7 work, ambient air is heated and rises, thereby form a negative pressuren zone in the casing casing below heater, cold air is inhaled in the casing casing by air inlet 5 heats, rise to air outlet 3 again and discharge, form free convection.In the present embodiment, electrothermal tube 7 is curved the U font with increase electrothermal tube 7 length, and is convenient to heat exchange and wiring.Radiating fin 6 is formed by two and is fixed with the straight line portion of U-shaped electrothermal tube 7 respectively.Radiating fin 6 is made by aluminium sheet, the aluminium sheet two ends strike out fin increases heat exchange area, fold up along center line then, burst is a circular arc, the interior diameter of circular arc is slightly less than the external diameter of electrothermal tube 7, seal in electrothermal tube 7 backs and clamp electrothermal tube 7 to reduce thermal resistance, be convenient to heat exchange and reduce the electrothermal tube temperature rise, prolong electrothermal tube service life and safety with rivet or screw 15.This heater also can replace with the fixing flat resistance silk of mica sheet, can save radiating fin because of it has enough heat exchange areas.

As shown in Figure 3, the air inlet 5 of back shroud 2 bottoms is a small square hole, also can be made as strip hole, can guarantee entering smoothly of air like this, can prevent that again careless hand from stretching as causing scald in the casing casing.The back shroud 2 of warmer is provided with the fixing bracing frame 16 of using, and has irregularly-shaped hole 17 on the bracing frame, but makes warmer can hang on the predetermined fixed screw on the wall and auto lock.

Embodiment two

As Fig. 6～shown in Figure 10, be another preferred embodiment of the present utility model.By Fig. 6～Figure 10 as can be known, the difference of electric heating device is among present embodiment electric heating device and the embodiment one: the present embodiment electric heating device is the horizontal type setting, and control box 8 is arranged at the lower left quarter of casing casing.
