The invention is realized by the following technical scheme: the clothes dryer comprises the fan, a driving motor and the air flue; the air flue is provided with the air outlet, wherein the bar screen device is arranged outside the air outlet of the air flue, the bar screen device is tightly fixed at the periphery of the air outlet and is in a hemispheric structure, the opening part of the bar screen device is closely jointed with the air outlet, the hemispheric part of the bar screen device protrudes out of the air flue and consists of net-shaped bar screens the array direction of which is consistent with the airflow outlet direction of the air outlet of the air flue.
Description
Technical field
The invention belongs to field of household appliances, be specifically related to a kind of wet clothes and article be carried out dry clothes drying device.
Background technology
Present widely used clothesdrier mostly adopts electrical heating, Steam Heating, hot air and hot water to heat the mode of equal energy source simple switched, comes wet clothes and article are carried out dried.The mode of these several heating, consumes energy is big, and drying efficiency is low, the time is long.Simultaneously, clothing is deposited in the machine after the drying, and is wrinkling easily, and because the inhomogeneous clothes fiber that easily makes of heating is impaired.Heat pump techniques is a kind ofly to cause it to produce the technology that phase transformation produces heat by compressed air, adopts heat pump techniques heating energy savings greatly.Heat pump comes down to a kind of heat lifting device, the effect of heat pump is a draw heat from surrounding environment, and it is passed to heated object (object that temperature is higher), its operation principle is identical with refrigeration machine, all according to contrary Carnot cycle work, different just operating temperature range is different.Usually heat pump assembly includes: compressor, condenser, evaporimeter, the pipeline that the pressure of the cold-producing medium of high pressure is carried out the throttling arrangement of step-down and connects these devices.By allowing working medium constantly finish the thermodynamic cycle process of evaporation (draw heat in environment) → compression → condensation (emitting heat) → throttling → evaporate again, thereby with the transfer of heat in the environment.Adopting the clothesdrier of heat pump assembly also is the important directions of the research and development of products in this field.
Therefore, clothesdrier can be categorized as in the prior art: electrical heating clothes dryer, Steam Heating dryer, hot air dryer, hot water heating dryer.Another kind of sorting technique in the prior art can be categorized as clothesdrier: intelligent dryer, quick dryer, low noise dryer, microwave clothes drier or the like.
Above-mentioned all clothesdriers include the ventilation unit that is arranged in the housing, and described ventilation unit includes: parts such as air channel, fan; The air outlet in air channel and housing are communicated with, and damp-heat air can be discharged engine body exterior, and described air channel generally includes a kind of metal spiral case device.In the prior art, the air outlet in described air channel is communicated with the position with housing, is presented as an opening that can lead to internal body that is positioned on the housing.In the long-term process of using, crawl into the parts that internal body destroys the inside for fear of insect and toy from this opening, when perhaps user and child's hand is not noted, put in internal body and, need increase a packaged unit at this aperture position by the damage of the fan that turned round.Guarantee that damp-heat air can successfully discharge engine body exterior, guarantee that simultaneously insect and toy are not easy to crawl into internal body, staff also can't put in internal body, avoids the generation of damage accident.Described packaged unit is generally a grid device that can seal the air channel air outlet, this grid device partly is positioned at inside, air channel, the air outlet in air channel can be covered fully, but taken the inner space, air channel, influence air-out, this grid device and fan distance is near simultaneously, behind the long-play or assembly precision when error is arranged, causes the generation of grid device and fan case of collision easily.
Summary of the invention
The object of the present invention is to provide clothesdrier; the air outlet in air channel is not blocked by grid device, can reduce the aerodynamic loss that is brought by airflow collision, and noise is lower; protectiveness to internal body is good simultaneously, can not cause grid device and fan case of collision to take place.
The present invention is achieved through the following technical solutions:
Clothesdrier includes fan, drive motors and air channel; Described air channel is provided with air outlet; The end face of serving as reasons spiral case with spiral curved surface and can hold the cylinder of clothing to be dried in described air channel surrounds the confined space that forms; Wherein, the air outlet outside in described air channel is provided with the grid device that is the hemisphere face structure; Described grid device is fastened on the periphery of described air outlet.
The opening portion of described grid device closely is connected with described air outlet, and the hemisphere face of described grid device partly protrudes from the outside in described air channel.
The hemisphere face part of described grid device is made of netted grid.
The orientation of described netted grid is consistent with described air channel air outlet air-flow air-out direction.
Described fan is a kind of centrifugal fan, and described centrifugal fan is positioned at the inside of spiral case; The middle part of described spiral case is provided with the centrifugal fan installing hole; The middle part of the end face of described cylinder is provided with the air inlet of being made up of a plurality of apertures.
To sum up, the invention has the beneficial effects as follows:
Clothesdrier of the present invention is because the air outlet outside in air channel is provided with grid device; Described grid device is fastened on the periphery of described air outlet; Grid device is the hemisphere face structure, and opening portion closely is connected with described air outlet, and the hemisphere face of grid device partly protrudes from the outside in described air channel; The hemisphere face part of grid device is made of netted grid; The orientation of netted grid is consistent with described air channel air outlet air-flow air-out direction.Therefore, grid device and fan distance can not cause grid device and fan case of collision to take place, and simultaneously, can reduce the aerodynamic loss that is brought by airflow collision, and noise is lower.
