Abstract
The utility model discloses a dryer which comprises a tumbler arranged in the case body of the dryer, an air intake channel communicating with the inner cavity of the tumbler is arranged on the front face of the case body, a PCT heating element is arranged in the air intake channel, an air exhaust channel is arranged at the other side of the tumbler, a shutter is arranged at the air inlet of the air intake channel of the dryer and is composed of an outer frame and vanes arrayed in turn, and the outer frame of the shutter can be a sheet on the front face of the case body or a frame embedded in the opening of the front face of the case body. Compared with the prior art, the dryer with an air intake device improves the air velocity, and maintains the concentration of the air and the smoothness of the air flow.
Description
Technical field
The utility model relates to a kind of tumbler dryer, relates in particular to a kind of tumbler dryer with the PCT heater element.
Background technology
Its course of work of tumbler dryer that present people generally use is wet wash ceaselessly to be rolled be exposed to airborne surface with renewal in cylinder, air in body forms under the good current intelligence, absorb the hydrone on wet wash surface by the heated drying air of convection current, avoid airing process clothing to be subjected to the pollution of dust and bacterium.The current heater element that generally adopts is PTC thermistor (being called for short PTC), and according to the heating principle of PTC, wind speed is very big to the influence of heating power, and in general, wind speed is big more, and power is big more.When not having wind, heater can not damage yet, but power can obviously descend.
So for dryer, when work, the wind speed that can offer the PTC element is big more, the effective power of PTC just can be given full play to more.The air flow structure of dryer is particularly important to making full use of of PTC heater element thus, and the smooth basic place of then designing for the dryer air flow structure along stable air-flow can be provided.And now, the dryer that has air-intake device that people generally the use air inlets that adopt bar shaped between poroid shape or individual layer more, the wind-force that such design not only can not provide at a high speed, concentrate to PCT, and air inlet blocks by the materials such as dust paper scrap in the external world easily and causes ventilation freely not suitable, thereby causes PTC heater element power not give full play to.At this moment, as improving the drying rated capacity of dryer, the just forced power that increases PTC causes cost to improve.
The utility model content
The utility model is in order to overcome the deficiencies in the prior art, a kind of a kind of tumbler dryer that improves present product deficiency to be provided, being issued to the specified drying capacity that increases dryer in situation about not raising the cost.
The technical scheme that the utility model solve the technical problem is, a kind of dryer,
Comprise the cylinder that is arranged in the dryer casing, be provided with air intake passage in the positive drum cavity that is communicated with of casing, the PCT heater members is located in the air intake passage, the opposite side of cylinder is provided with the exhaust passage, the air inlet place of dryer air intake passage is provided with shutter, and this shutter is made up of housing and the blade that is arranged in order.The shutter housing can be the sheet material in casing front, also can be the framework that is embedded in the positive perforate of casing.
The utility model further design is: the blade of shutter is arranged by front and back two rows; Front-seat blade and housing are in the same plane, and back row's blade is with front-seat parallel.This can increase the draught area of air inlet, increases air mass flow.
The utility model further designs: the cross section of back row's blade is inverted V-shaped, and this can strengthen the wind-guiding efficient of blade, reduces the air drag of air inlet.
In addition, the corresponding PTC heater spare of back row's blade not heating position can also be provided with protruding position, so effectively intercepts air-flow and contacts with athermic position among the PTC, improves wind concentration and imports the PTC heating position.
In addition, the spacing unanimity between the front-seat blade, the spacing unanimity between the row's blade of back can make the mould simplicity of design, and is easy to process.
The dryer that has air-intake device of the present utility model compared with prior art more can improve wind speed, keep the concentrating of wind-force, air-flow freely suitable.Particularly the designed shutter of casing air inlet also has the enclosing cover of a band filter course that cooperates with it, Shuan Ceng protection can guarantee that more air enters after smooth suitable the stablizing of dryer like this, can prevent effectively that also extraneous materials such as dust paper scrap from blocking air inlet and causing the smooth following current of ventilation to lead to, and load and unload very conveniently, be easy to clean; The cross section that shutter adopts two row's blade designs, particularly back to arrange blade is inverted V-shaped and caves in the air channel, can effectively reduce windage, can improve wind speed under the same air blast power, makes airflow more freely suitable; This also directly impels the PTC heating power to improve, and improves the specified drying capacity of dryer indirectly.

The specific embodiment
A kind of dryer that has air-intake device of the present utility model comprises: casing 1, shutter 2, housing 3, blade 4, protruding position 5.
In the utility model embodiment 1, as Fig. 1, Fig. 2, shown in Figure 3, the air inlet of dryer is the shutter that forms through stamping procedure on casing 1 same sheet material, this shutter 2 is a housing 3 with the Board material for box, be made up of 42 blades that are arranged in order 4, the blade 4 of shutter 2 is divided into two rows by front and back; Spacing unanimity between the front-seat blade is in the same plane with housing 3; Back row's vanes punching press is caved in parallel with front-seat blade to air channel, the spacing between its blade.
In embodiment 2 of the present utility model, as Fig. 4, shown in Figure 5, on the basis of embodiment 1, back row's blade is improved design, being designed to of back row's blade among the embodiment 2: back row's blade of embodiment 1 riglet is stamped into cross section is inverted V-shaped.
Among the embodiment 3 of the present utility model, as Fig. 6, shown in Figure 7, on back row's blade basis of embodiment 2 with corresponding PTC not heating position stamp out equal with front-seat blade protruding position 5.
When dryer is worked, air is after row's blade guiding is distributed behind the shutter 2 of air inlet, directly advertise PCT, PCT institute caloric value enters drum cavity with air, because air inlet design perfect adaptation fluid mechanics principle, under same air blast power, can improve the air intake wind speed, the PCT heating power of equal rated power is increased.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
