Description

Use warm-air drier more

The utility model relates to a kind of warm-air drier.

In the prior art, warm-air drier comprises spiral case, be arranged in the spiral case by the blade of driven by motor and be positioned at the heating wire of air-out passage, warm-air drier is mainly used in air in the heating clamber to improve indoor temperature.Existing warm-air drier can not change original air channel when the power supply of cut-off parts heating wire, so its purposes of malleable not.So, if warm-air drier is used to dry by the fire hand or be used to dry up hair or baking by the period of the day from 11 p.m. to 1 a.m, the power of existing warm-air drier and ducting outlet are all too big.

The purposes that the purpose of this utility model is to provide a kind of air channel by the conversion warm-air drier to change warm-air drier use warm-air drier more.

The technical solution of the utility model is: it comprises spiral case, is arranged at the impeller by driven by motor in the spiral case inner chamber, the heater shell that is connected with the spiral case oral area, the heater that is positioned at heater shell inner cavity air channel, is provided with movable snail tongue in the formed air-out passage of described spiral case.Described heater comprises first heater, second heater, be provided with the air channel dividing plate that extends along air-out direction between described first heater and second heater, form the first air-out passage and the second air-out passage behind the inner chamber of this dividing plate interval, air channel heater shell; Described snail tongue has two operating positions, and an operating position is the sealing first air-out passage, and another operating position is to open the first air-out passage.

The utility model compared with prior art has following advantage:

After changing the position of snail tongue, can make two air-out passages that hot blast is arranged simultaneously or have only an air channel that hot blast is arranged, can carry out the indoor conversion of heating, drying by the fire functions such as hand, can not occur the obvious increase of noise after the conversion of air channel.
