Description

  The present invention relates to a dehumidifier and an operation method thereof. Dehumidifiers include those whose indoor air is intended for dehumidification, those whose clothing is intended for dehumidification, and those whose both are intended for dehumidification. Further, the dehumidifier includes a dryer that dries a room or clothing to be dehumidified.

  The dehumidifier operates a processing air fan disposed in the processing air path, and takes in air (processing air) from the outside (for example, the room to be dehumidified) from the suction port. When the processing air passes through the dehumidification rotor, moisture is adsorbed and discharged from the outlet as dry air. In addition, the dehumidifier operates a regeneration air fan disposed in a regeneration air path that is a closed circuit, and circulates air (regeneration air) in the regeneration air path. The regeneration air is heated by a heater and collects (absorbs) moisture adsorbed by the dehumidifying rotor when passing through the dehumidifying rotor. Thereafter, the recovered water is stored as condensed water by being cooled by a heat exchanger.

  Patent Document 1 discloses a dehumidifier in which the output of a heater is decreased stepwise in accordance with a decrease in the humidity of sucked processing air. However, this dehumidifier cannot be sufficiently dried when the object to be dehumidified (dried) is clothing, and a portion that is freshly dried may remain.

Japanese Patent No. 3899218

  This invention makes it a subject to provide the dehumidifier which can fully dry the clothing which is a dehumidification object.

  The present invention provides a dehumidification rotor that adsorbs moisture from the processing air and recovers the moisture in the regeneration air, a heating unit that heats the regeneration air and the dehumidification rotor, and a first dehumidification that operates the heating unit with a first output. A determination step for determining whether or not to increase the output of the heating means during the execution of the first dehumidification step based on a predetermined determination criterion, and the determination of an increase in output is established in the determination step There is provided a dehumidifier comprising a control unit that performs a dehumidifying process that includes a second dehumidifying step that causes the heating means to operate at a second output that is higher than the first output.

  The present invention is also directed to a dehumidifier comprising a dehumidification rotor that adsorbs moisture from the processing air and recovers the moisture in the regeneration air, and a heating unit that heats the regeneration air and the dehumidification rotor. During execution of the first dehumidifying step operated by output, it is determined whether or not to increase the output of the heating means based on a preset criterion, and when the determination of output increase is established, the heating means is Provided is a method of operating a dehumidifier that performs a second dehumidifying step that operates at a second output that is higher than the first output.

  Clothing that is one of the dehumidifying objects can promote drying by only blowing a lot of air even when the temperature is low at the start of operation that contains a lot of moisture. However, as drying progresses, it becomes impossible to dry only with wind, and therefore it is preferable to increase the temperature of the air to be blown. And since this invention raises the output of a heating means based on the preset criteria, when a dehumidification object is clothing, it can fully dry, without leaving a freshly dried part.

  Here, when judging the configuration of having the first dehumidifying step of the first output and the second dehumidifying step of the second output higher than the first output, the non-heating step in which the output of the heating means is stopped is performed. Exclude only the process of operating the heating means. Further, for example, when the dehumidification process having the same output is executed after the first dehumidification process with the output set to be weak (first output) (weak → weak), these are regarded as one dehumidification process. Further, when the execution time of the dehumidifying process is short and does not affect the dehumidification (drying) of the clothes, the dehumidifying process is regarded as substantially absent.

  For example, a non-heating process in which the output is stopped is executed between a first dehumidifying process in which the output is set to be weak (first output) and a second dehumidifying process in which the output is set to the medium setting (second output). In this case (weak → stop → medium), since the non-heating step is not included, this operation method is included in the present invention in which the heating means is increased from the first output to the second output.

  In addition, after setting the output to the medium setting, if the output is set to the weak setting, and then the output is set to the strong setting (medium → weak → strong), after the first dehumidifying step with the output set to the weak setting (first output), Since it has the 2nd dehumidification process made into the strong setting (2nd output) of output higher than 1st output, this operating method is included in this invention which raises a heating means. Also, if the execution time of the weak setting dehumidification process is short and does not affect the dehumidification (drying) of clothing, it is considered that the weak setting dehumidification process is substantially absent (medium → strong). Since the second dehumidification step is set to a strong setting (second output) higher than the first output after the first dehumidification step with the output set to the middle setting (first output), this operation method also increases the output. It is included in the present invention.

  In addition, after setting the output to the weak setting, if the output is set to the strong setting, and then the output is set to the medium setting (weak → high → medium), after the first dehumidifying step with the output set to the weak setting (first output), Since it has the 2nd dehumidification process made into the strong setting (2nd output) of output higher than 1st output, this operating method is included in this invention which raises a heating means. Also, if the execution time of the strong setting dehumidification process is short and does not affect the dehumidification (drying) of clothing, it is considered that there is virtually no strong setting dehumidification process (weak → medium). Since the second dehumidifying step is set to a medium setting (second output) higher than the first output after the first dehumidifying step where the output is weakly set (first output), this operation method also increases the output. It is included in the present invention.

  The control unit stops the operation of the heating unit after executing the finishing step of operating the heating unit with a third output higher than the first output. Here, the third output includes the same setting as the second output. If it does in this way, since high temperature air can be finally blown with respect to clothing, the whole can be fully dried, without leaving a portion which is not dry.

  The finishing process ends when a preset execution time has elapsed. In this way, when the room (space) where the clothes are dried is narrow, it can be surely dried without leaving a portion that is undried. That is, when the room is small, the indoor air can be dehumidified (dried) relatively quickly, but the clothes may be left in a state of being dried. Therefore, the clothing can be surely dried by performing a finishing process in which the heating means is operated at a high output for a set time at the end of the dehumidifying process.

  The third output of the heating means operated in the finishing process is higher than the second output of the heating means operated in the second dehumidification process. In this way, since the output of the heating means is increased in stages as the clothes are dried, the clothes can be surely dried while suppressing wasteful power consumption.

  In the dehumidifying process, the output of the heating means is increased stepwise from the start of the operation of the heating means after the start of operation until the finishing process is executed. Thus, since the output of the heating means is lowered at the start of operation with good drying efficiency, power consumption can be suppressed and energy can be saved.

  The determination criterion has a preset set humidity, and the control unit increases the output of the heating unit when the detected humidity of the processing air detected by the humidity detecting unit falls below the set humidity. If it does in this way, the output of a heating means can be changed according to the dryness of clothing.

  Further, the determination criterion has a preset lower limit execution time, and the control unit maintains the output of the heating means regardless of the humidity detected by the humidity detection means before the lower limit execution time elapses, When the detected humidity falls below the set humidity after the elapse of the lower limit execution time, the output of the heating means is increased. In this way, it is possible to prevent the output of the heating means from being raised when the detected humidity temporarily falls below the set humidity due to an external factor such as the entry of dry outside air.

  In addition, the determination criterion has a preset upper limit execution time, and when the upper limit execution time has elapsed, the control unit increases the output of the heating unit regardless of the humidity detected by the humidity detection unit. In this way, it is possible to prevent the operation at a low temperature from being continued when the detected humidity does not fall below the set humidity due to external factors such as the entry of outside air containing a large amount of moisture.

  Since the dehumidifier of the present invention increases the output of the heating means based on a preset criterion, when the object to be dehumidified is clothing, the dehumidifier can be sufficiently dried without leaving a dry portion.

(Details of heater control)
The microcomputer 800 serving as the control unit is selected according to the mode selected by the user among the drying mode (manual dehumidification processing), the air blowing mode, the eco mode (first automatic dehumidification processing), and the night drying mode (second automatic dehumidification processing). The fans 400 and 450 and the heater 250 are controlled.

  When the drying mode is selected, the processing air fan 400 and the regeneration air fan 450 are operated with the selected set air volume via the double shaft motor 490. Further, the switch elements 259a and 259b are turned on to operate all the PTC heaters 251A to 251C, and the heater 250 is operated at a strong (third output) setting.

  When the air blowing mode is selected, the processing air fan 400 and the regeneration air fan 450 are operated with the selected set air volume via the double shaft motor 490. Further, the switch elements 259a and 259b are turned off, and all the PTC heaters 251A to 251C are stopped.

  When the eco mode is selected, the processing air fan 400 and the regeneration air fan 450 are operated with the strongest air volume via the double shaft motor 490. Further, the switch elements 259a and 259b are controlled to be turned on and off based on a preset determination criterion to operate the PTC heaters 251A to 251C, and the output of the heater 250 is increased stepwise.

  When the night drying mode is selected, the processing air fan 400 and the regenerative air fan 450 are operated with the weakest air volume via the double shaft motor 490. Further, the switch elements 259a and 259b are turned on to operate all the PTC heaters 251A to 251C, and the heater 250 is operated at a strong (third output) setting.

  Next, heater control in the eco mode (first automatic dehumidification process) will be specifically described.

  The eco mode includes first to third dehumidifying steps for operating the heater 250 with a set output. In the first dehumidifying step, the PTC heater 251C is turned on, and the heater 250 is operated with the first output (weak). In the second dehumidifying step, the PTC heaters 251A and 251B are turned on, and the heater 250 is operated with the second output (medium). In the third dehumidifying step, the PTC heaters 251A to 251C are turned on, and the heater 250 is operated with the third output (strong). In addition, after the third dehumidifying step, a finishing step for maintaining the state in which the heater 250 is operated at the high output third output is provided.

  In the first to third dehumidifying processes, it is determined whether or not the output of the heater 250 is increased (whether or not to shift to the next process) by the first to third determining processes that are processed in parallel. Specifically, in the first dehumidifying step, it is determined by the first determining step whether or not the second output (middle) is higher than the first output (move to the second dehumidifying step). In the second dehumidifying step, it is determined by the second determining step whether or not the second output is increased to a third output (strong) having a higher output than the second output (shift to the third dehumidifying step). In the third dehumidifying step, it is determined by the third determining step whether or not to move to the final finishing step while maintaining the same output as the third output. The finishing process is performed for a set execution time, and when this execution time has elapsed, all heater controls are completed.

  As shown in FIG. 12, the microcomputer 800 as a determination unit makes a determination based on a determination criterion set in advance in each determination step. This criterion is stored in a ROM (storage means) (not shown) built in the microcomputer 800.

  The ROM stores set humidity Hs1 to Hs3 to be compared with the humidity H of the processing air detected by the humidity sensor 801 as a first determination criterion. The microcomputer 800 maintains the current output of the heater 250 when the detected humidity H of the processing air detected by the humidity sensor 801 is equal to or higher than the set humidity Hs. Further, when the humidity falls below the set humidity Hs (the determination of increase in output is established), the output of the heater 250 is increased.

  In the ROM, lower limit execution times Tmin1 to Tmin3 for maintaining the current output state regardless of the humidity H of the processing air are set as the second determination criterion. The microcomputer 800 maintains the current output of the heater 250 regardless of the humidity H detected by the humidity sensor 801 before the lower limit execution time Tmin elapses. Further, when the lower limit execution time Tmin elapses, the output of the heater 250 can be increased.

  In the ROM, upper limit execution times Tmax1 to Tmax3 at which the next dehumidifying process is shifted (the output is increased) regardless of the humidity H of the processing air are set as a third determination criterion. The microcomputer 800 maintains the current output of the heater 250 when the upper limit execution time Tmax has not elapsed and the detected humidity H is equal to or higher than the set humidity Hs. Even if the detected humidity H is equal to or higher than the set humidity Hs, when the upper limit execution time Tmax has elapsed, the output of the heater 250 is increased.

  Here, the humidity of the indoor air by operating the dehumidifier 1 is such that when the clothes containing moisture are dried in the room, the moisture contained in the clothes is released into the room when the operation is started. Go up. Thereafter, the humidity in the room including the moisture of the clothes gradually decreases due to the dehumidifying effect of the dehumidifier 1. Moreover, the humidity of indoor air may change temporarily due to external factors such as the intrusion of outside air. Specifically, when dry outside air flows into the room and the airflow flows into the dehumidifier 1, the humidity H detected by the humidity sensor 801 temporarily decreases. On the other hand, when outside air containing a large amount of moisture flows into the room and the airflow flows into the dehumidifier 1, the humidity H detected by the humidity sensor 801 temporarily increases.

  On the other hand, in this embodiment, the lower limit execution time Tmin for maintaining the output of the heater 250 regardless of the detected humidity H is set. Therefore, when the humidity H in the original room is low, it can be prevented that the process immediately shifts to the next dehumidifying step. Moreover, it can prevent that it transfers to the following dehumidification process immediately because the dry external air flows in. Further, an upper limit execution time Tmax for increasing the output of the heater 250 regardless of the detected humidity H is set. Therefore, when the outside air containing a lot of moisture flows in, it is not possible to shift to the next dehumidifying step, and it is possible to prevent the operation at a low temperature.

  In addition, when the room (space) where clothes are dried is small, the indoor air can be dehumidified relatively quickly, but the clothes may be left in a dry state. Therefore, in the present embodiment, the final step of the heater control for increasing the output of the heater 250 stepwise is a finishing step that is executed for a preset execution time Tfin. Therefore, even if the clothes are dried in a narrow space, the clothes can be surely dried without leaving a freshly dried portion.

  FIG. 13 shows an example of the transition determination criteria for the next dehumidifying process set in each dehumidifying process. In the first dehumidifying process in which the heater 250 is operated with the first output, the set humidity Hs1 is set to 60%, the lower limit execution time Tmin1 is set to 120 minutes, and the upper limit execution time is set as a first determination criterion for shifting to the next process. Tmax1 is set to 300 minutes. In the second dehumidifying process in which the heater 250 is operated with the second output, the set humidity Hs2 is set to 50%, the lower limit execution time Tmin2 is set to 60 minutes, and the upper limit execution time is set as a second determination criterion for shifting to the next process. Tmax2 is set to 150 minutes. In the third dehumidifying process in which the heater 250 is operated with the third output, the set humidity Hs3 is set to 40%, the lower limit execution time Tmin3 is set to 30 minutes, and the upper limit execution time is set as a third determination criterion for shifting to the next process. Tmax3 is set to 80 minutes. In the final finishing step in which the heater 250 is operated with the third output, the execution time Tfin is set to 20 minutes.

  Next, the eco mode control by the microcomputer 800 will be specifically described.

  As shown in FIG. 14A, when the eco mode is executed (operation start), first, the double-shaft motor 490 control in step S1 and the control of the first dehumidifying process in steps S2 to S5 are executed simultaneously. In step S1, the double shaft motor 490 is operated to operate the fans 400 and 450 with a strong wind.

  In the first dehumidifying process from step S2 to step S5, first, in step S2, the switch element 259a is turned on, the switch element 259b is turned off, the PTC heater 251C is operated, and the heater 250 is operated at a low output. Let Next, in step S3, the process waits until the lower limit execution time Tmin1 has elapsed. Next, in step S4, it is determined whether or not the humidity H detected by the humidity sensor 801 is lower than the set humidity Hs1. If the detected humidity H is not lower than the set humidity Hs1, the process proceeds to step S5. If the detected humidity H is lower than the set humidity Hs1, the process proceeds to step S6. In step S5, it is determined whether or not the upper limit execution time Tmax1 has elapsed. If the upper limit execution time Tmax1 has not elapsed, the process returns to step S4. If the upper limit execution time Tmax1 has elapsed, the process proceeds to step S6.

  When the first dehumidifying step is completed, the second dehumidifying step from step S6 to step S9 is executed. Specifically, in step S6, the switch element 259a is turned off, the switch element 259b is turned on, the PTC heaters 251A and 251B are operated, and the heater 250 is operated at a medium output. In step S7, the process waits until the lower limit execution time Tmin2 elapses. Next, in step S8, it is determined whether or not the humidity H detected by the humidity sensor 801 is lower than the set humidity Hs2. If the detected humidity H is not lower than the set humidity Hs2, the process proceeds to step S9. If the detected humidity H is lower than the set humidity Hs2, the process proceeds to step S10. In step S9, it is determined whether or not the upper limit execution time Tmax2 has elapsed. When the upper limit execution time Tmax2 has not elapsed, the process returns to step S8, and when the upper limit execution time Tmax2 has elapsed, the process proceeds to step S10.

  When the second dehumidifying step is completed, the third dehumidifying step from step S10 to step S13 is executed. Specifically, in step S10, the switch elements 259a and 259b are turned on, the PTC heaters 251A to 251C are operated, and the heater 250 is operated at a high output. In step S11, the process waits until the lower limit execution time Tmin3 has elapsed. Next, in step S12, it is determined whether or not the humidity H detected by the humidity sensor 801 is lower than the set humidity Hs3. If the detected humidity H is not lower than the set humidity Hs3, the process proceeds to step S13. If the detected humidity H is lower than the set humidity Hs3, the process proceeds to step S14 in FIG. 14B. In step S13, it is determined whether or not the upper limit execution time Tmax3 has elapsed. If the upper limit execution time Tmax3 has not elapsed, the process returns to step S12. If the upper limit execution time Tmax3 has elapsed, the process proceeds to step S14 in FIG. 14B.

  As shown in FIG. 14B, when the third dehumidifying process is completed, the finishing process from step S14 to step S15 is executed. Specifically, in step S14, the switch elements 259a and 259b are turned on, the PTC heaters 251A to 251C are operated, and the heater 250 is operated at a high output. Next, in step S15, the process waits until the lower limit execution time Tmin3 elapses. When the lower limit execution time Tmin3 elapses, the process proceeds to step S16.

  When the finishing process is completed, a cool-down (non-heating) process from step S16 to step S18 is executed. Specifically, in step S16, the switch elements 259a and 259b are turned off, the operations of the PTC heaters 251A to 251C are stopped, and the heater 250 is brought into a non-heated state. Next, in step S17, the apparatus waits until a body cooling time Tcd (for example, 3 minutes) elapses. Then, when the airframe cooling time Tcd has elapsed, in step S18, the both-axis motor 490 is stopped, and the dehumidifying process in the eco mode is ended.

  In this way, the dehumidifier 1 reduces power consumption and saves energy by reducing the output from the heater 250 at the start of operation that can accelerate drying only by blowing a lot of air even if the temperature is low. . In addition, when drying progresses and drying becomes difficult with only the wind, the output of the heater 250 is increased to increase the temperature of the air to be blown. Therefore, the clothes to be dehumidified can be sufficiently dried without leaving a freshly dried portion. it can. In particular, the heater control of the dehumidifying process is terminated after the execution of the high output finishing process in which the output of the heater 250 is increased. Moreover, the final finishing process of the present embodiment is executed until a preset time Tfin has elapsed. Therefore, even if the room (space) where clothes are dried is narrow, it can be surely dried without leaving a portion that is undried.

(Second Embodiment)
FIG. 15 shows an eco mode (automatic dehumidification process) of the dehumidifier 1 of the second embodiment. In the second embodiment, not only the output of the heater 250 but also the air flow rate of the processing air fan 400 is changed based on the set determination criteria (set humidity Hs and execution time Tmin, Tmax). This is different from the first embodiment. Specifically, in the first dehumidifying step, moisture is released from the garment, and the airflow is set to the maximum until the humidity of the processing air reaches the upper limit. Thereafter, the air volume is decreased to the minimum level and gradually increased. Moreover, when it transfers to a 2nd dehumidification process, the ventilation volume of the process air fan 400 is similarly reduced to the minimum, and is raised gradually. If it does in this way, the same operation and effect as a 1st embodiment can be acquired, and control according to the dry state of clothes becomes possible further.

  In addition, the dehumidifier 1 of this invention is not limited to the structure of the said embodiment, A various change is possible.

  For example, in the above embodiment, the output of the heater 250 is increased stepwise from the beginning to the end after the start of the dehumidification process (weak → medium → strong → strong). Is not limited to this configuration.

  Specifically, the process to be determined when determining the configuration of the stepwise increase of the present invention is only the process in which the heater 250 is operated, excluding the non-heating process in which the output of the heater 250 is stopped. Further, when the dehumidifying process having the same output is continuously executed (for example, weak → weak), these are regarded as one dehumidifying process. Further, when the execution time of the dehumidifying process is short and does not affect the dehumidification (drying) of the clothes, the dehumidifying process is regarded as substantially absent.

  That is, the non-heating process in which the output is stopped is executed between the first dehumidifying process in which the output is set to the weak setting (first output) and the second dehumidifying process in which the output is set to the medium setting (second output). In the case (weak → stop → medium), since the non-heating step is not included, it is included in the present invention that increases the output stepwise.

  In addition, after setting the output to the medium setting, if the output is set to the weak setting, and then the output is set to the strong setting (medium → weak → strong), after the first dehumidifying step with the output set to the weak setting (first output), Since it has the 2nd dehumidification process made into the strong setting of output higher than 1st output, this operating method is included in this invention which raises a heating means. Also, if the execution time of the weak setting dehumidification process is short and does not affect the dehumidification (drying) of clothing, it is considered that the weak setting dehumidification process is substantially absent (medium → strong). Since the second dehumidification step is set to a strong setting (second output) higher than the first output after the first dehumidification step with the output set to the middle setting (first output), this operation method also increases the output. It is included in the present invention.

  In addition, after setting the output to the weak setting, if the output is set to the strong setting, and then the output is set to the medium setting (weak → high → medium), after the first dehumidifying step with the output set to the weak setting (first output), Since it has the 2nd dehumidification process made into the strong setting (2nd output) of output higher than 1st output, this operating method is included in this invention which raises a heating means. Also, if the execution time of the strong setting dehumidification process is short and does not affect the dehumidification (drying) of clothing, it is considered that there is virtually no strong setting dehumidification process (weak → medium). Since the second dehumidifying step is set to a medium setting (second output) higher than the first output after the first dehumidifying step where the output is weakly set (first output), this operation method also increases the output. It is included in the present invention.

  In addition, the present invention is not limited to the configuration in which the output of the heater 250 is increased step by step (weak → medium → strong), but from a weak setting (first output) to a strong setting (second output higher than the first output). The structure which raises to is included. Further, the output of the heater 250 may be weak → medium → weak → strong, and any process for increasing the output of the heater 250 is included in the present invention.

  In the above embodiment, the final step of the heater control is that the heater 250 has the strongest (100%) output, but may have a medium (66%) output.
