Description

A kind of hair dryer

Technical field

The utility model relates to household appliance technical field more particularly to a kind of hair dryers.

Background technique

The existing hair dryer entered the wind from Handleset, including the shell connecting with Handleset, fan unit setting exists In Handleset, Handleset is equipped with air inlet, and air-flow enters interior of shell after entering Handleset from air inlet, in order to just In the installation of Handleset inner structural member, Handleset is divided into multiple portions, various pieces, which are assembled together, has assembly building Gap causes air-flow to leak；Moreover, Handleset is equipped with electronic device, for example switch, in order to facilitate the use of the user, switch is set It sets in the top of fan unit, the setting of switch needs the aperture on Handleset, and air-flow can leak from switch, cause air quantity With the leakage of wind pressure, the setting of sealing structure will lead to assembly complexity again and improve.

In addition, air inlet is set on Handleset, from the air outlet blowout on shell, airflow direction enters shell Shi Yaogai Become larger about 90 °, due to the change of airflow direction, air quantity, air loss can be generated, in the prior art by setting air guide structure Part causes the loss of air quantity, wind pressure since airflow direction changes to reduce.

Utility model content

In order to solve the problems in the prior art, the utility model provides a kind of hair dryer for obtaining larger air quantity, wind pressure.

The technical solution of the utility model is as follows:

A kind of hair dryer, including shell and with the Handleset of cage connection, extend to outlet air from the air inlet of hair dryer Mouthful main air duct, be arranged in main air duct and from air inlet enter the fan unit of hair dryer for suction airstream and for heating this The heating unit of air-flow, the fan unit include flabellum and the motor for driving flabellum to rotate, wherein the fan unit It is arranged in Handleset, the air inlet is arranged on Handleset, is additionally provided in the Handleset for conveying main wind The guide duct of road air-flow, the air inlet are at least set to the side wall of Handleset, and the guide duct is located at the air inlet set on side wall The top of mouth.

Benefit is to be drawn into the air-flow of main air duct by fan unit directly to pass through guide duct and conveyed, and is on the one hand led Air hose forms sealing, and the probability that the air-flow of main air duct is compromised from assembly gap reduces, to reduce air quantity and air loss； When Handleset is equipped with electronic device, main air duct and electronic device do not have to individually do sealing structure again, simplify structure；Wind-guiding Pipe can also play buffer function, noise reduction, damping to the sound of main air duct air-flow, and wind-guiding hose is set to the top of air inlet, good Place is the sectional area maximum that guide duct receives the air-flow entered from air inlet, improves the air quantity entered in guide duct.

Preferably, the main air duct include the vertical section in the Handleset and be located in shell and with vertical section Angled axial section, the vertical section are connected to axial section by air flow inlet, and it is vertical that the guide duct limits this Section.

Benefit is that main air duct is non-linear air duct, and air-flow changes direction meeting when air-flow enters axial section from vertical section Air quantity, air loss are caused, guide duct, which extends at air flow inlet, send the air-flow of vertical section to axial section by guide duct, Reduce airflow-reversing bring air quantity, air loss.

Preferably, the upper end of the guide duct is L, 0mm≤L≤20mm at a distance from air flow inlet.

Benefit is to prevent air-flow from causing wind pressure, air quantity to reduce from the slot leakage of Handleset；As L > 20mm, handle The fit-up gap of component, which is likely to result in air-flow and leaks, causes wind pressure, air quantity to reduce.

Preferably, the inner cylinder for limiting axial section is equipped in the shell, the guide duct has close to one end of inner cylinder Flange, the flange is between inner cylinder and shell.

Benefit is that guide duct is fixed, make hair dryer at work, prevent from leading hose and be moved under the action of air-flow Position or hair dryer are generated by guide duct when external force to be shifted, and guarantees air-flow being delivered to axial section, and reduce air quantity and wind pressure Loss.

Preferably, the wind-guiding pipe sleeve is on fan unit.

Benefit is that the air-flow of fan unit suction is directly entered guide duct, is reduced in windage, and then reduce air quantity and wind pressure Loss.

Preferably, the motor further includes frame, and the flabellum is set in frame, and the wind-guiding pipe sleeve is on frame.It is good Place is that guide duct plays the role of damping, noise reduction.

Preferably, the Handleset includes the fixation bracket for fan attachment unit and covers the right-hand side outside it Handle, the support bracket fastened side wall are equipped with the card slot for fan attachment unit, and the guide duct is caught in the card slot.

Benefit is to reduce the vibration that user experiences from Handleset, and can reduce noise.

Preferably, the Handleset includes the fixation bracket for fan attachment unit and covers the right-hand side outside it Handle, the fixed bracket have the opening along its axial direction, and the fan unit is set in opening, and the fan unit passes through Outdoor handle and fixed bracket are fixed；Benefit is, convenient for the assembly of fan unit, and simplifies the installation step of Handleset, reduces Cost improves efficiency；

Alternatively, the Handleset includes the fixation bracket for fan attachment unit and covers the outdoor handle outside it, The fixed bracket is tubular and is divided axially into two halves along it, consolidates after the fixation support fastening that the fan unit passes through two halves formula It is fixed.Benefit is, convenient for the assembly of fan unit, and fixes reliable；

Preferably, the Handleset includes the fixation bracket for fan attachment unit and covers the right-hand side outside it Handle, the guide duct are located between fixed bracket and outdoor handle and cover on fixed bracket, and the fan unit is set to fixed branch In frame.

Benefit is that guide duct forms sealing, prevents air quantity, air loss.
