(Embodiment)
Fig. 1 is the figure of the structure of the dehumidifier representing embodiments of the present invention.As shown in figure 1, dehumidifier includes:Setting Dehumidification portion 2 in main body 1, air supplying part 3, regenerative heater 4, control unit 5, temperature sensor 6, humidity sensor 7, people's perception Sensor 8 and operation display part 9.Temperature sensor 6, humidity sensor 7 and people's detecting sensor 8 are connected with control unit 5.
Dehumidification portion 2 includes regeneration fan 21, the dehumidifying rotor 22 rotating, heat exchanger 23 and water tank 24.
The air being inhaled into from interior by the driving of air supplying part 3, in dehumidifying rotor 22 quilt after making heat exchanger 23 cool down Moisture absorption, the air after dehumidifying is released to interior again, and indoor air is dehumidified.
Dehumidifying rotor 22 a side by the moisture after moisture absorption, because the opposing party in dehumidifying rotor 22 is reproduced heater Hot blast after 4 heating and evaporate, cooled in heat exchanger 23, condensation and accumulate in water tank 24.
Humidity sensor 7 detects the relative humidity Hr of the ambient air of main body 1.Temperature sensor 6 detects the periphery of main body 1 Temperature Tr of air.
Control unit 5, according to the detected value of humidity sensor 7 and temperature sensor 6 both sides or a side, controls dehumidification portion 2, send Wind portion 3 and regenerative heater 4.And, control unit 5 controls dehumidification portion 2 and air supplying part 3, thus carries out cloth drying operating or removes Wet automatic operating.
When cloth drying operates at cloth drying operation start, temperature Tr according to ambient air and relative humidity Hr set The setting that the drying of cloth drying operating completes.It is then based on according to per certain time(At regular intervals)The periphery tried to achieve Temperature Tr of air and the rate of drying Tt of relative humidity Hr calculating medicated clothing.And then by this rate of drying Tt according to often certain(Gu Fixed)Time adds up, and is judged as that the drying of medicated clothing terminates when rate of drying obtained by this is cumulative reaches the dry setting completing, Dehumidifier is automatically stopped.In addition, in cloth drying operation start, such as the temperature in ambient air is 20 DEG C, relative humidity In the case of 70%, the setting that completes of drying be 5200 [-].
Automatically operating is for dehumidifying, and when the detected value of humidity sensor 7 is higher than the humidity of regulation, dehumidifier operates automatically, When the detected value of humidity sensor 7 becomes the humidity of regulation, dehumidifier is automatically stopped.Dehumidifier terminates in cloth drying operating Afterwards, proceed the automatic operating that dehumidifies.In addition it is stipulated that humidity for example, 50% to 60%.
In addition, though be not shown in operation display part 9, but there is user and can select to terminate in cloth drying operating Proceed operation mode i.e. " the Keep Dry of automatic operating that dehumidifies afterwards(Keep drying)" switch.
Embodiments of the present invention are characterised by, the automatic operating of dehumidifying after cloth drying operating terminates proceeds.
Hereinafter, the flow chart with the details of the motion of the dehumidifier that represents embodiments of the present invention is that Fig. 2 is carried out Illustrate.Fig. 2 is to represent the moment starting to switch that the cloth drying of the operation display part 9 pressing Fig. 1 from user operates Rise, the flow chart of the action automatically terminating until cloth drying operates.
In S101, with humidity sensor 7, the temperature sensor 6 of Fig. 1 detects that temperature Tr of ambient air is wet with relative respectively Degree Hr.Then, in S102, set and aridity Dx is completed by the drying that temperature Tr and the relative humidity Hr of ambient air specify Dx table.Microcomputer as the control unit 5 of Fig. 1(Hereinafter referred to as microcomputer), extract from Dx table and set and detect Temperature Tr of ambient air and the corresponding drying of relative humidity Hr complete aridity Dx.Here, Dx value is tried to achieve by experiment, as Table is stored in microcomputer.
Then temperature Tr detecting ambient air in such as every 1 minute at regular intervals after S103 and relative humidity Hr, Microcomputer implements the process of below S104 based on this data.
I.e. in S106, temperature Tr according to ambient air and relative humidity Hr ask for total amount of heat Ir and absolutely of ambient air To humidity Xr.Then in S107, with the relative humidity of the neighbouring air of medicated clothing for 100%, total amount of heat Ir according to ambient air with Absolute humidity Xr speculates the absolute humidity Xc of air near medicated clothing.
Then, in S108, the control unit 5 of Fig. 1 is definitely wet to medicated clothing nearby the absolute humidity Xc of air and ambient air The difference of degree Xr is multiplied by factor alpha, calculates rate of drying Tt(=α(Xc-Xr)).
Rate of drying Tt, cumulative in S109, it is stored in the memorizer in microcomputer as accumulated value ∫ Tt.
In S110, aridity Dx is completed to the drying setting in accumulated value ∫ Tt and S102 obtained by cumulative in S109 and carries out Relatively.If ∫ were Tt >=Dx?Result be "No"(NO), then confirm whether measuring interval t is more than 1 minute(S111), jump to S105.It is then detected that temperature Tr of ambient air and relative humidity Hr, temperature Tr based on ambient air for the microcomputer and relative humidity Hr enforcement is processed.If result is "Yes"(YES), then terminate cloth drying operating(S112).
Then, in S11 then, the operation display part 9 of Fig. 1 is proceeded to remove after cloth drying operating terminates The operation mode of wet automatic operating is whether Keep Dry is set and is checked.If "No", then dehumidifier is complete for here Shut down.If "Yes", then dehumidifier starts the automatic operating that dehumidifies(S12).
Dehumidifier starts to dehumidify automatic operating, thus, dry operating just terminated humidity between back room still at a relatively high and It is also possible to operating eliminates uncomfortable state automatically by dehumidifying in the case of uncomfortable, the humidity in room is protected Hold in comfortable state.
Here, when dehumidifier starts to dehumidify automatic operating, dehumidification portion 2, air supplying part 3 and regenerative heater 4 will not stop, Detect the relative humidity Hr of ambient air by humidity sensor 7.Higher than the humidity of regulation in the detected value of humidity sensor 7 In the case of, dehumidifier is remained in operation by operation mode corresponding with the detected value of humidity sensor 7, therefore automatically transports to dehumidifying The switching turning accelerates.And then because dehumidification portion 2, air supplying part 3 and regenerative heater 4 do not stop, so with dehumidification portion 2, air supplying part 3 Situation about stopping with regenerative heater 4 is compared, and reduces for starting required power consumption again.
In addition, in the case that the detected value of humidity sensor 7 is lower than the humidity of regulation, pressing one using humidity sensor 7 The relative humidity Hr of the such as every 1 minute detection ambient air in fixed interval, and continue to remove with the minimum operation mode of dehumidifying effect The operating of wet end 2, air supplying part 3 and regenerative heater 4.Here, after the stipulated time, the detected value ratio of humidity sensor 7 In the case that the humidity of regulation is low, dehumidifier stops dehumidifying and automatically operates.
On the other hand, after the stipulated time, in the case that the detected value of humidity sensor 7 is higher than the humidity of regulation, Dehumidification portion 2, air supplying part 3 and regenerative heater 4 are remained in operation by operation mode corresponding with the detected value of humidity sensor 7, The switching therefore automatically operating to dehumidifying accelerates.And then the situation phase with the stopping of dehumidification portion 2, air supplying part 3 and regenerative heater 4 Ratio reduces for starting required power consumption again.
In addition, the air quantity of cloth drying operating is bigger than the air quantity of the automatic operating that dehumidifies, the wind therefore with cloth drying operating The air quantity identical situation that amount operates automatically with dehumidifying is compared, and the time of cloth drying operating shortens.The time that i.e. medicated clothing soaks Shorten, therefore, it is possible to suppress the breeding of the miscellaneous bacteria during cloth drying.And then, the time due to producing moisture from medicated clothing shortens, So the high- humility state of interior shortens, the generation of mushroom etc. can be suppressed.
In addition, dehumidifying automatically operate in target humidity set point be relative humidity below about more than 40% 70% when, use The range of choice of person becomes big.
In addition, in dehumidifying operates automatically, being operated by automatically setting the timing of certain certain time, being prevented from user Forget.
In addition, dehumidifier has people's detecting sensor 8 of sensing people.When people's detecting sensor 8 senses people, will dehumidify certainly The target humidity setting value of dynamic operating is changed to relative humidity about 65%.By in such manner, it is possible to the humidity in offer room will not be excessively It is dried, without compromising on the comfortable environment of skin.
In addition, for dehumidification portion 2, using desiccant(Desiccant)Mode is illustrated but it is also possible to be compressor Mode or hybrid mode.
As described above, the dehumidifier of embodiments of the present invention is thus it is speculated that the aridity of medicated clothing is terminating dry operating.And And, the dehumidifier of the present invention has and proceeds, after cloth drying operating terminates, the switch of automatic operating that dehumidifies, and does in medicated clothing Dry operating carries out the automatic operating that dehumidifies after terminating, therefore, it is possible to the humidity in room is maintained at comfortable state.
