Description
Technical field
The utility model relates to field of kitchen electric appliance, is specifically related to a kind of frequency-variable kitchen ventilator of good heat dissipation.
Background technology
Smoke exhaust ventilator is also known as range hood, it is a kind of kitchen appliance purifying kitchen environment, it is arranged on above the health energy-saving range hood cooking stove of kitchen, the harmful oil smoke produced in the refuse of cooking stove burning and cooking process can be taken away rapidly, outside discharge chamber, decreasing pollution, purify air, and having gas defence, explosion-proof safety guarantee effect, the adjustment rotation speed of fan that traditional smoke exhaust fan cannot be in good time according to oil smoke amount, thus power consumption is higher.
For solving this problem, mandate publication number is that the patent of invention of CN2418397Y provides a kind of frequency-veriable cooking-fume exhauster, and this frequency-veriable cooking-fume exhauster is provided with control circuit and connects and control three-phase induction motor with drive fan in inside; In this control circuit, power-supply unit connects three-phase output converter unit, smog detecting unit is connected with temperature detecting unit and output signal gives microcomputer control unit, microcomputer control unit connects and output signal gives display timing unit, and microcomputer control unit connects and output signal gives three-phase output converter unit; This frequency-veriable cooking-fume exhauster can by indoor temperature height, oil smoke amount number; and make the suitable speed suction of motor fan; but due to the temperature of smoke exhaust inside higher; and converter unit heating itself is larger; in real work, converter unit often can lose efficacy because of overheated, affects the normal work of smoke exhaust.
Utility model content
For overcoming deficiency of the prior art, the utility model provides the frequency-variable kitchen ventilator of a kind of working stability, good heat dissipation.
For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of frequency-variable kitchen ventilator of good heat dissipation, comprise housing, be arranged at the impeller in housing, motor and smoke discharging pipe, it is characterized in that: also comprise converter unit, radiator fan and smoke detector, described housing bottom surface has pump orifice, air-vent in the middle of described impeller is relative with the pump orifice of housing, described motor is installed on enclosure interior, impeller is installed on motor shaft, described converter unit is connected with motor, described hull outside is provided with frequency conversion tank, converter unit and radiator fan are arranged in frequency conversion tank, described frequency conversion tank is provided with air inlet and air outlet, radiator fan is arranged at air inlet, air outlet is communicated with smoke discharging pipe, described smoke detector is arranged at housing bottom surface.
Further, the air outlet place of described frequency conversion tank is provided with check-valves.
Further, the air inlet of described frequency conversion tank is provided with screen pack.
Further, the heat detector being arranged at housing bottom surface is also comprised.
Further, described housing bottom surface is provided with greasy dirt groove.
Further, described greasy dirt groove has sewage draining exit.
Seen from the above description, converter unit is positioned in the independent cabinet of casing of cooker hood outside by the frequency-variable kitchen ventilator of the good heat dissipation that the utility model provides, avoid the hot environment of enclosure interior, and arrange radiator fan to dispel the heat to converter unit, thus to converter unit, there is good radiating effect, ensure the normal work of frequency converter.
Accompanying drawing explanation
Fig. 1 is the structural representation of the frequency-variable kitchen ventilator of the utility model good heat dissipation.
Fig. 2 is the sectional view of the frequency-variable kitchen ventilator of the utility model good heat dissipation.
Fig. 3 is the overall schematic of the frequency-variable kitchen ventilator of the utility model good heat dissipation.
Detailed description of the invention
Below by way of detailed description of the invention, the utility model will be further described.
As shown in Figure 1 to Figure 3, the frequency-variable kitchen ventilator of described good heat dissipation comprises housing 1, be arranged at the impeller 2 in housing 1, motor 3, smoke discharging pipe 4, converter unit 5, radiator fan 6, smoke detector 7 and heat detector 8, the bottom surface 11 of housing 1 has pump orifice 12, air-vent in the middle of impeller 2 is relative with the pump orifice 12 of housing 1, it is inner that motor 3 is installed on housing 1, impeller 2 is installed on motor shaft, converter unit 5 is connected with motor 3, converter unit 5 and radiator fan 6 are arranged in the frequency conversion tank 13 of housing 1 outside, frequency conversion tank 13 is provided with air inlet 131 and air outlet 132, radiator fan 6 is arranged at air inlet 131 place, air inlet 131 place is provided with screen pack 133, air outlet 132 is communicated with smoke discharging pipe 4, smoke detector 7 and heat detector 8 are arranged at the bottom surface 11 of housing 1, air outlet 132 place of frequency conversion tank 13 is provided with check-valves 9, the bottom surface 11 of housing 1 is provided with greasy dirt groove, greasy dirt groove has sewage draining exit.
The frequency-variable kitchen ventilator using method of described good heat dissipation is as follows: the size of smoke detector 7 perception oil smoke, heat detector 8 sense temperature height, and by Signal transmissions to control unit, control unit will control to adjust the frequency of converter unit 5 after signal transacting, frequency is improved during the large or temperature height of oil smoke, otherwise then reduce frequency, and then control the rotating speed of impeller 2; Radiator fan 6 pairs of converter units 5 dispel the heat, and avoid converter unit 5 overheated, and the check-valves 9 that air outlet 132 place of frequency conversion tank 13 is arranged can prevent the oil smoke in smoke discharging pipe 4 from pouring in down a chimney in frequency conversion tank 13.
Above are only some detailed description of the invention of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
