Detailed description of the invention
Embodiments of the invention are described below in detail, and the example of described embodiment is shown in the drawings.Below with reference to The embodiment that accompanying drawing describes is exemplary, it is intended to is used for explaining the present invention, and is not considered as limiting the invention.
With reference to Fig. 1, the structure of the dryer 100 of the embodiment of the present invention is described in detail first below.
As it is shown in figure 1, dryer 100 according to embodiments of the present invention can include housing, inner core 1, humidity detector, Motor 23, air channel 2 and heat pump.Inner core 1, motor 23, air channel 2 and heat pump can be located in housing.
Specifically, inner core 1 has receiving chamber 11, and medicated clothing to be dried is placed in receiving chamber 11.In motor 23 can drive Cylinder 1 rotates.Air channel 2 has air inlet 21 and air outlet 22, and air outlet 22 connects with accommodating chamber 11.Can be by dry by air outlet 22 It is interior to dry medicated clothing that hot-air is passed through receiving chamber 11.
Heat pump can include compressor 3, throttling arrangement 8, condenser 4, vaporizer 5 and cooling fan 7, compressor 3 Being located at outside air channel 2, condenser 4 and vaporizer 5 are located in air channel 2, and are connected with compressor 3 respectively, and cooling fan 7 is suitable to drive Air flow direction compressor 3 is to carry out heat exchange with compressor 3.Alternatively, condenser 4 is fin-tube type condenser 4, and simple in construction is changed The thermal efficiency is high.
Alternatively, vaporizer 5 is Fin and tube evaporator 5, simple in construction, and heat exchange efficiency is high.
As it is shown in figure 1, vaporizer 5 and condenser 4 set gradually along the flow direction of air in air channel 2, throttling arrangement 8 Being connected between condenser 4 and vaporizer 5, cold-producing medium circulates between compressor 3, condenser 4, throttling arrangement 8 and vaporizer 5 Flowing, and discharge substantial amounts of heat, so that the air in air channel 2 to be heated.Wherein, condenser 4 carries out heat release, and vaporizer 5 is used for Refrigeration.Alternatively, throttling arrangement 8 is capillary tube, electronic expansion or heating power expansion valve, simple and reliable for structure.
Specifically, throttling arrangement 8 is positioned at outside air channel 2, thus is conducive to the structure simplified in air channel 2 to reserve more suitable In the space that air-flow flows through, certainly the invention is not restricted to this, in further embodiments, throttling arrangement 8 can also be positioned at air channel 2 In.
Specifically, dryer 100 is when carrying out dryer 100, and heat pump is started working, and accommodates the air in chamber 11 Enter air channel 2, first pass through vaporizer 5 and carry out cool-down dehumidification, be then passed through condenser 4 and carry out heat temperature raising, become heated dry air After flow to air outlet 22, and so that medicated clothing to be dried in air outlet 22 flows to accommodate chamber 11, finally flow to air channel 2, and First passing around vaporizer 5 and carry out cool-down dehumidification, such iterative cycles completes clothes drying process.
Dryer 100 can also include that impeller 24, motor 23 are located at outside air channel 2, and motor 23 has motor shaft 231, impeller 24 are located on motor shaft 231 and at air outlet 22 and accommodate between chamber 11, and motor 23 can drive impeller 24 to rotate with by air channel 2 Interior air-flow imports and accommodates in chamber 11.
Humidity detector may be provided on the sidewall of inner core 1, and humidity detector can be used for detecting the wet of inner core 1 undergarment Degree, and detected value is fed back to the controller of dryer 100.Alternatively, humidity detector is humidity sensor 9, thus, and knot Structure is simple, is quick on the draw.
In some embodiments of the invention, in cooling fan 7 being located at the housing of dryer 100 and adjacent to compression Machine 3 is arranged, not only simple in construction, and the wind being conducive to cooling fan 7 to send directly blows to compressor 3, thus improves air Heat exchange efficiency with compressor 3.
In some embodiments of the invention, dryer 100 includes that guide duct 6, guide duct 6 are connected to air channel 2 and compression So that the air-flow flowing through compressor 3 is guided to air channel 2 between machine 3, flow through after the air-flow of compressor 3 carries out heat exchange with compressor 3 Temperature raises, and utilizes guide duct 6 to participate in the drying of internal cylinder 1 undergarment in this fraction guides air channel 2, can be in certain journey Drying efficiency is improved on degree.
As it is shown in figure 1, the entrance point 61 of guide duct 6 is arranged adjacent to compressor 3, the port of export 62 of guide duct 6 and air channel 2 phase Connection, the direction that the port of export 62 of guide duct 6 may be configured as towards air outlet 22 tilts.So, air is from the outlet of guide duct 6 End 62 is when flowing to air channel 2, can be along the direction oblique flow towards air outlet 22, thus in beneficially guide duct 6 imports air channel 2 Air flow air outlet 22, reduces air flow resistance in air channel 2.
In some embodiments of the invention, one end (port of export the most as shown in Figure 1 that guide duct 6 connects with air channel 2 62) can be located between condenser 4 and vaporizer 5.As it is shown in figure 1, the port of export 62 of guide duct 6 is located at condenser 4 and vaporizer 5 Between, thus, after the air of guide duct 6 imports air channel 2, can flow to accommodate chamber 11 after condenser 4 heats further, from And the temperature flowing to accommodate the air in chamber 11 can be improved, improve drying effect further.
Alternatively, the cross-sectional area of guide duct 6 can be gradually reduced by the airflow direction along guide duct 6.Thus heat can be made Air air quantity in time flowing to air channel 2 is more concentrated, and raising hot-air flows to wind speed during air channel 2.
Below with reference to the control method of Fig. 2 description dryer according to embodiments of the present invention, described dryer is above-mentioned reality Execute the dryer in example.
Control method according to embodiments of the present invention comprises the steps:
As in figure 2 it is shown, when drying program opened by dryer, detect the wet of inner core undergarment by humidity detector Degree, and the first humidity value and first setting value A1 of detection are compared;Specifically, dryer includes controller, controls Device can be connected with humidity detector, to judge the first humidity value and the size of the first setting value A that humidity detector detects. When drying program opened by dryer, the motor of dryer and compressor successively start.
When the first humidity value≤the first setting value A1, controlled refrigeration but fan is opened, so that cooling fans drive Surrounding air flows to compressor, thus is conducive to improving the heat exchange efficiency between air and compressor, reduces the temperature of compressor, Thus reduce compressor work, reduce the power consumption of compressor, be conducive to reducing the flow direction to a certain extent simultaneously and accommodate intracavity Heat, improves the utilization rate of heat to a certain extent, improves drying efficiency.Alternatively, the span of A1 be 5%≤A1≤ 10%.
Persistently detect the humidity of inner core undergarment, and the second humidity value and second setting value A2 of detection are compared; Specifically, controller can compare according to the second humidity value of humidity detector detection and the second setting value A2
When the second humidity value≤the second setting value A2, illustrate that clothes dryer completes, thus dryer is shut down.Wherein Two setting value A2 < the first setting values A1.Alternatively, the span of A2 meets: A2≤3%.
It is understood that in the clothes drying process of dryer, humidity detector persistently detects the humidity of inner core undergarment.
The control of the dryer being illustrated in figure 3 in prior art in the power consumption of the control method of dryer and the present embodiment The comparison diagram of method processed, can be shown clearly that by Fig. 3 in the control method of the present embodiment, the power consumption of compressor is reduced.
