Abstract
The utility model relates to a warm-air machine. The utility model comprises an electric heating element, blades and an electric motor which are arranged in a shell body. A heating and interlocking circuit is arranged in the shell body. An interlocking circuit is serially connected by an adjustable temperature controller, an electric motor, an alternating current mutual-inductor normally-closed contact and a second electric heating element which are mutually connected in parallel, and a first electric heating element and an alternating current mutual-inductor normally open contact which are connected in parallel by the heating and interlocking circuit. The heating and interlocking circuit is respectively and serially connected with a fuse, a heat protector and a switch, and is connected with a power supply. The circuit of the utility model is provided with the heating and interlocking circuit, the utility model guarantees the warm-air machine to blow out the warm air when initially outwards blows, and alters the abuse of the past warm-air machine that the cold air is blown out when initially runs. Users can adjust the temperature according to the own concrete requirements, and thus the utility model is suitable for places with different requirements. The utility model has the advantages of simple and reasonable circuit structure, safety, stable warm air conveying, low cost, adjustment on heating temperature and no cold air blowing.
Description
Technical field
The utility model relates to a kind of warm-air drier.
Background technology
Common warm-air drier is when just beginning to start, fan blade can be worked simultaneously with electric heater, perhaps prior to electric heater work, needs the regular hour because electrical heating elements heats up, at this moment fan blade can blow out cold wind, and the most user of warm-air drier order of this structure feels quite dissatisfied.
The utility model content
The purpose of this utility model be to provide a kind of circuit structure advantages of simple, safe and reliable, can carry out the warm-air drier that heating-up temperature is regulated and do not blown a cold wind over, to overcome weak point of the prior art.
A kind of warm-air drier by this purpose design, comprise the electrical heating elements, fan blade and the motor thereof that are arranged in the housing, its architectural feature is to be provided with the heating interlock circuit in the housing, this heating interlock circuit comprises adjustable temperature controller, motor, D.C mutual-inductor normally-closed contact and second electrical heating elements after parallel with one another, with in parallel after first electrical heating elements and D.C mutual-inductor normally opened contact, serial connection back forms interlock circuit.
Above-mentioned heating interlock circuit is received power supply successively with after fuse, thermal protector, switch are connected in series.
When the utility model is started working, the direct conducting of adjustable temperature controller, the motor in parallel with adjustable temperature controller is in short-circuit condition, can not outwards blow; Second electrical heating elements is because of being connected in parallel on D.C mutual-inductor normally-closed contact two ends, and is in short circuit, do not generate heat; First electrical heating elements in parallel with the D.C mutual-inductor normally opened contact gets electric, begins heating.
When the temperature of first electrical heating elements was raised to adjustable temperature controller setting value, adjustable temperature controller disconnected, and D.C mutual-inductor gets electric, and the D.C mutual-inductor normally-closed contact disconnects, and second electrical heating elements gets electric, begins heating; D.C mutual-inductor normally opened contact closure, first electrical heating elements are stopped heating by short circuit.Motor gets electric, drives fan blade and begins outside air-supply; The wind that send this moment is hot blast.
The utility model is provided with the heating interlock circuit on circuit, guaranteed warm-air drier at the beginning outwards the blowing just blow out warm braw, changed the drawback that just blows out cold wind when warm-air drier has just brought into operation in the past; The user can also carry out the adjusting of temperature according to the concrete needs of oneself, to adapt to the different places that require.
That the utility model circuit structure advantages of simple, safe and reliable, warm braw transmit is stable, low cost of manufacture, can carry out the adjusting of heating-up temperature and do not blow a cold wind over.
Description of drawings
Fig. 1 is the utility model one embodiment circuit connection diagram.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1, be provided with the heating interlock circuit in the housing of this warm-air drier, this heating interlock circuit comprises adjustable temperature controller P, motor M, D.C mutual-inductor normally-closed contact K2 and the electrical heating elements T2 after parallel with one another, with in parallel after electrical heating elements T1 and D.C mutual-inductor normally opened contact K1, serial connection back forms interlock circuit; The heating interlock circuit is received power supply with fuse F, thermal protector RU, switch SW after being connected in series again successively.
Claims (2)
1. warm-air drier, comprise the electrical heating elements, fan blade and the motor M thereof that are arranged in the housing, it is characterized in that being provided with in the described housing heating interlock circuit, this heating interlock circuit comprises adjustable temperature controller P, motor M, D.C mutual-inductor normally-closed contact K2 and the electrical heating elements T2 after parallel with one another, with in parallel after electrical heating elements T1 and D.C mutual-inductor normally opened contact K1, serial connection back forms interlock circuit.
2. warm-air drier according to claim 1 is characterized in that described heating interlock circuit receives power supply with fuse F, thermal protector RU, switch SW after being connected in series successively.
