Abstract

A dehumidifier 1 comprises a dehumidifying rotor 200, a heater 250 and controller (microcomputer) 800. The dehumidifying rotor 200 absorbs moisture from process air and releases the absorbed moisture to purge air. The heater 250 heats the purge air and the dehumidifying rotor 200. The controller 800 performs a dehumidifying process including a first dehumidifying step, a determining step and a second dehumidifying step. In the first dehumidifying step, the controller 800 operates the heater 250 by a first output. The determining step is performed during the first dehumidifying step. In the determining step, the controller 800 determines whether or not to make the output rise based on a set judgement standard, and transforms to the second dehumidifying step when the controller 800 determines the rising output. In the second dehumidifying step, the controller 800 operates the heater 250 by a second output which is larger than the first output.

Description

Dehumidifier and its operation method

The present invention relates to a dehumidifier and a method of operating the same. The dehumidifier includes, in addition to the indoor air, a person who dehumidifies the clothing, and both of them are dehumidification targets. Further, the dehumidifier includes a dryer that dries the interior of the dehumidification object and the clothes.

The dehumidifier operates the process air fan disposed in the process air path, and extracts air (process air) from the outside (for example, the room to be dehumidified) from the suction port. The treatment air adsorbs moisture when passing through the dehumidification rotor, and is discharged as dry air from the outlet. Further, the dehumidifier operates the reconditioning air fan disposed in the reconditioning air path that is the closed path, and circulates the air (regeneration air) in the reconditioning air path. The regeneration air is heated by a heater, and the moisture adsorbed by the dehumidification rotor is recovered (moisture absorbing) when the rotor is dehumidified. Thereafter, the recovered water is stored as aggregated water by cooling with a heat exchanger.

Patent Document 1 discloses a dehumidifier that reduces the output of the heater in a stepwise manner as the humidity of the process air sucked in is lowered. but, In the dehumidifier, when the object to be dehumidified (dry) is clothing, there is a case where the portion that is not sufficiently dried and remains semi-dry is left.

An object of the present invention is to provide a dehumidifier that can sufficiently dry a dehumidifying object, that is, a garment.

The present invention provides a dehumidifier comprising: a dehumidification rotor that adsorbs moisture from the process air and recovers the regeneration air; the heating means heats the regeneration air and the dehumidification rotor; and the control unit performs heating The first dehumidification project that is operated by the first output, and the determination of whether or not the output of the heating means is increased during the execution of the first dehumidification project, and the determination of the output increase in the determination process are determined based on a predetermined criterion. At the time of establishment, the heating means performs the dehumidification process of the second dehumidification process of the second output operation which is higher than the first output.

Moreover, the present invention provides a method for operating a dehumidifier, which is provided with a dehumidification transfer that adsorbs moisture from the process air and recovers the regeneration air. In the dehumidifier that heats the regeneration air and the heating means of the dehumidification rotor, in the execution of the first dehumidification process in which the heating means operates in the first output, it is determined whether or not the heating is performed based on a predetermined criterion. The output of the means is increased, and when the determination of the output rise is satisfied, the operation method of the dehumidifier of the second dehumidification operation that causes the heating means to output higher than the first output is executed.

The clothing of one of the dehumidification objects can be dried by using only a large amount of air to be delivered, even if the temperature is low at the start of the operation including a large amount of moisture. However, if drying is carried out, it becomes impossible to dry only by the use of the wind, so that it is preferable to raise the temperature of the air to be blown. According to the present invention, since the output of the heating means is increased in accordance with a predetermined criterion, when the object to be dehumidified is clothing, the portion which is semi-dry can be sufficiently dried without being left.

Here, when it is determined that the first dehumidification project having the first output and the second dehumidification project having the second output higher than the first output are configured, the non-heating process for stopping the output of the heating means is excluded, and only The project that operates the heating means. Further, for example, after the first dehumidification project in which the output is set to the weak setting (first output), the dehumidification process (weak→weak) which is the same output is executed, and these are regarded as one dehumidification process. Moreover, when the execution time of the dehumidification project is short and does not affect the degree of dehumidification (drying) of the clothes, the dehumidification process is substantially absent.

For example, when the first dehumidification project that sets the output to the weak setting (the first output) and the second dehumidification project that sets the output to the middle setting (the second output), the non-heating project that stops the output is executed (weak → Stop → Medium), does not include non-heating engineering, so the operation method is included in the heating means from the first 1 The present invention is outputted to the second output.

In addition, after setting the output to the middle setting, the output is set to the weak setting, and then the output is set to the strong setting (medium → weak → strong), and the first dehumidification project is set to the weak setting (first output). After that, there is a second dehumidification project that is set to a higher output (second output) than the first output. Therefore, the operation method is included in the present invention in which the heating means is raised. Moreover, when the execution time of the weakly set dehumidification project is short and does not affect the degree of dehumidification (drying) of the clothes, the weakly set dehumidification project is substantially absent (medium→strong), so the output is set to medium (the After the first dehumidification process of the 1st output, the second dehumidification project is set to be stronger than the first output (second output). Therefore, the operation method is also included in the present invention for increasing the output.

In addition, after the output is set to a weak setting, the output is set to a strong setting, and then the output is set to medium setting (weak → strong → medium), and the first dehumidification project is set to the weak setting (first output). After that, there is a second dehumidification project that is set to a higher output (second output) than the first output. Therefore, the operation method is included in the present invention in which the heating means is raised. Moreover, when the execution time of the strongly set dehumidification project is short and does not affect the degree of dehumidification (drying) of the clothes, the dehumidification project that is strongly set is substantially absent (weak → medium), so the output is set to a weak setting (the first) After the first dehumidification process of the 1st output, the second dehumidification project is set to be higher than the first output (second output). Therefore, the operation method is also included in the present invention for increasing the output.

The control unit stops the operation of the heating means after the completion of the completion of the third output operation in which the heating means is output higher than the first output. Here, the third output contains the second output The same settings are made. In this way, the clothes can be sent to the high-temperature air at the end, so that the semi-dry portion does not remain, and the whole can be sufficiently dried.

The completion of the foregoing is completed when a predetermined execution time has elapsed. In this way, when the room (space) of the clothes type is narrow, the semi-dry portion does not remain, and it can be surely dried. That is, when the room is narrow, the indoor air can be dehumidified (dried) relatively quickly, but there is a state in which the clothes are left in a semi-dry state. Therefore, the final stage of the dehumidification process is to complete the work of operating the heating means at a high output for a set time, and it is possible to surely dry the clothes.

The third output of the heating means that operates in the completion of the work is output higher than the second output of the heating means that operates in the second dehumidification process. In this way, as the clothes are dried, the output of the heating means is increased stepwise, so that the clothes can be surely dried while suppressing useless power consumption.

In the dehumidification treatment, the output of the heating means is gradually increased until the completion of the operation of the heating means after the start of the operation. In this way, the output of the heating means is lowered at the start of the operation with high drying efficiency, so that the power consumption can be suppressed and energy saving can be achieved.

The determination criterion includes a preset set humidity; and the control unit increases the output of the heating means when the detected humidity of the processing air detected by the humidity detecting means is lower than the set humidity. In this way, the output of the heating means can be changed depending on the degree of drying of the clothes.

Further, the aforementioned criterion is a predetermined lower limit The control unit maintains the output of the heating means without detecting humidity detected by the humidity detecting means before the elapse of the lower limit execution time, and the detected humidity is lower than the setting after the lower limit execution time elapses In the case of humidity, the output of the heating means is increased. In this way, it is possible to prevent an external factor such as intrusion of dry external air, and when the detected humidity is temporarily lower than the set humidity, the output of the heating means rises.

Further, the determination criterion includes a preset upper limit execution time, and the control unit increases the output of the heating means without detecting humidity detected by the humidity detecting means when the upper limit execution time elapses. In this way, it is possible to prevent an external factor such as intrusion of an external air containing a large amount of water, and to continue the operation at a low temperature when the detected humidity is not lower than the set humidity.

In the dehumidifier of the present invention, the output of the heating means is increased in accordance with a predetermined criterion. Therefore, when the object to be dehumidified is clothing, the portion which is semi-dry can be sufficiently dried without being left.

(details of heater control)

The control unit, that is, the microcomputer 800 controls the fan in the mode selected by the user in the drying mode (manual dehumidification process), the air supply mode, the energy saving mode (the first automatic dehumidification process), and the nighttime dry mode (the second automatic dehumidification process). 400, 450 and heater 250.

When the drying mode is selected, the process air fan 400 and the regeneration air fan 450 are operated by the two-axis motor 490 at the selected set air volume. Moreover, the switching elements 259a and 259b are turned on, so that all The PTC heaters 251A to 251C operate to cause the heater 250 to operate with a strong (third output) setting.

When the air supply mode is selected, the process air fan 400 and the regeneration air fan 450 are operated by the two-axis motor 490 at the selected set air volume. Further, the switching elements 259a and 259b are turned off, and all of the PTC heaters 251A to 251C are placed in a stopped state.

When the energy saving mode is selected, the process air fan 400 and the regeneration air fan 450 are operated by the two-axis motor 490 with the strongest air volume. Further, the switching elements 259a and 259b are turned ON/OFF according to a predetermined criterion, and the PTC heaters 251A to 251C are operated to increase the output of the heater 250 in a stepwise manner.

When the nighttime dry mode is selected, the process air fan 400 and the regeneration air fan 450 are operated by the two-axis motor 490 with the weakest air volume. Further, the switching elements 259a and 259b are turned on, and all of the PTC heaters 251A to 251C are operated to cause the heater 250 to operate with a strong (third output) setting.

Next, the heater control for the energy saving mode (first automatic dehumidification process) will be described more specifically.

The energy saving mode includes first to third dehumidification processes for causing the heater 250 to operate at the set output. In the first dehumidification system, the PTC heater 251C is turned on, and the heater 250 is operated at the first output (weak). In the second dehumidification system, the PTC heaters 251A and 251B are turned on, and the heater 250 is operated in the second output (middle). In the third dehumidification engineering, the PTC heaters 251A to 251C are set to the ON state, and the addition is performed. The heater 250 operates at the third output (strong). In addition, after the third dehumidification process, a completion process in which the third output operation of the heater 250 is performed at a high output is performed.

In the first to third dehumidification projects, it is determined whether or not the output of the heater 250 is raised (whether or not it is transferred to the next project) through the first to third determination items of the parallel processing. Specifically, in the first dehumidification process, it is determined whether or not the second output (middle) that is higher than the first output is output by the first determination process (transfer to the second dehumidification project). In the second dehumidification project, it is determined whether or not the third output (strong) that is higher than the second output is output by the second determination project (transfer to the third dehumidification project). In the third dehumidification project, it is determined by the third determination project whether or not the transition to the last completed project is performed while maintaining the same output as the third output. Furthermore, the completion of the engineering operation is performed at the set execution time, and after the execution time, all the heater control ends.

As shown in FIG. 12, the microcomputer 800 as the determination unit performs determination in accordance with a predetermined determination criterion in each determination item. This judgment criterion is stored in a ROM (memory means) not shown in the microcomputer 800.

In the ROM, as the first criterion, the set humidity Hs1 to Hs3 which are compared with the humidity H of the process air detected by the humidity sensor 801 is stored. The microcomputer 800 maintains the current output of the heater 250 when the detected humidity H of the process air detected by the humidity sensor 801 is equal to or higher than the set humidity Hs. Further, when the setting is lower than the set humidity Hs (the determination of the output rise is satisfied), the output of the heater 250 is made Rise.

In the ROM, as the second criterion, the presence or absence of the humidity H of the processing air is set, and the lower limit execution time Tmin1 to Tmin3 of the current output state is maintained. The microcomputer 800 maintains the current output of the heater 250 regardless of the detected humidity H of the humidity sensor 801 before the elapse of the lower limit execution time Tmin. Further, when the lower limit execution time Tmin is passed, the output of the heater 250 can be raised.

In the ROM, as the third criterion, the presence or absence of the upper limit execution time Tmax1 to Tmax3 regarding the humidity H of the process air and the next dehumidification process transition (increasing the output) is set. When the microcomputer 800 does not pass the upper limit execution time Tmax and the detected humidity H is equal to or higher than the set humidity Hs, the microcomputer 800 maintains the current output of the heater 250. Further, even when the detected humidity H is equal to or higher than the set humidity Hs, the output of the heater 250 is raised when the upper limit execution time Tmax is passed.

Here, the humidity of the indoor air caused by the operation of the dehumidifier 1 is in a state in which the clothes containing moisture are dried indoors, and the moisture contained in the clothes is released to the room when the operation is started, so that the humidity is gradually increased. Thereafter, by the dehumidifying effect of the dehumidifier 1, the humidity in the room containing the moisture of the clothes is gradually lowered. In addition, the humidity of the indoor air temporarily changes due to external influence such as intrusion of external air. In detail, the dry external air flows into the room, and when the airflow flows to the dehumidifier 1, the humidity H detected by the humidity sensor 801 is temporarily lowered. On the other hand, the outside air containing a large amount of moisture flows into the room, and when the airflow flows to the dehumidifier 1, the humidity H detected by the humidity sensor 801 is temporarily increased.

On the other hand, in the present embodiment, the lower limit execution time Tmin at which the output of the heater 250 is maintained regardless of the detected humidity H is set. Therefore, when the humidity H in the original room is low, it is possible to prevent immediate transfer to the next dehumidification project. Moreover, by using the inflow of dry external air, it is possible to prevent immediate transfer to the next dehumidification project. Further, an upper limit execution time Tmax in which the detected humidity H is raised and the output of the heater 250 is raised is set. Therefore, it is possible to prevent the inflow of an external air containing a large amount of moisture, and it is impossible to transfer to the next dehumidification process and continue to operate at a lower temperature.

In addition, when the room (space) of the clothes type is small, the air in the room can be dehumidified relatively quickly, but the clothes are left in a semi-dry state. Therefore, in the present embodiment, the final project of the heater control for increasing the output of the heater 250 in a stepwise manner is a completion process for executing the preset execution time Tfin. Therefore, even if the clothes in a narrow space are dried, for example, the semi-dry portion may not remain, and the clothes are surely dried.

An example of the transfer determination criterion set to the next dehumidification project in each dehumidification process is disclosed in FIG. In the first dehumidification process in which the heater 250 is operated at the first output, the set humidity Hs1 is set to 60% and the lower limit execution time Tmin1 is set to 120 minutes as the first criterion for shifting to the next process, and the upper limit is executed. The time Tmax1 is set to 300 minutes. In the second dehumidification process in which the heater 250 is operated in the second output, the set humidity Hs2 is set to 50% and the lower limit execution time Tmin2 is set to 60 minutes as the second determination criterion for shifting to the next process, and the upper limit is executed. The time Tmax2 is set to 150 minutes. In the third dehumidification project in which the heater 250 is operated at the third output, it is transferred to the next project. In the third criterion, 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 Tmax3 is set to 80 minutes. In the final completion of the third operation of the heater 250, the execution time Tfin is set to 20 minutes.

Next, the control of the energy saving mode by the microcomputer 800 will be described more specifically.

As shown in FIG. 14A, when the energy-saving mode is executed (starting operation), first, the two-axis motor 490 control of step S1 and the control of the first dehumidification process from step S2 to step S5 are simultaneously performed. In step S1, the two-axis motor 490 is operated to cause the fans 400 and 450 to operate in strong wind.

In the first dehumidification process from step S2 to step S5, first, in step S2, the switching element 259a is turned on, and the switching element 259b is turned off, and the PTC heater 251C is operated to allow the heater 250 to be operated. Operate with low output. Next, in step S3, it waits until the lower limit execution time Tmin1 elapses. Next, in step S4, it is judged whether or not the detected humidity H caused by the humidity sensor 801 is lower than the set humidity Hs1. Then, when the detected humidity H is not lower than the set humidity Hs1, the process proceeds to step S5, and when the detected humidity H is lower than the set humidity Hs1, the process proceeds to step S6. In step S5, it is judged whether or not the upper limit execution time Tmax1 has passed. Then, when the upper limit execution time Tmax1 has not elapsed, the process returns to step S4, and when the upper limit execution time Tmax1 has elapsed, the process proceeds to step S6.

When the first dehumidification project is completed, the process proceeds from step S6 to The second dehumidification project of step S9. Specifically, in step S6, the switching element 259a is turned off, the switching element 259b is turned on, the PTC heaters 251A, 251B are operated, and the heater 250 is operated in the middle. Next, in step S7, it waits until the lower limit execution time Tmin2 elapses. Next, in step S8, it is judged whether or not the detected humidity H caused by the humidity sensor 801 is lower than the set humidity Hs2. Then, when the detected humidity H is not lower than the set humidity Hs2, the process proceeds to step S9, and when the detected humidity H is lower than the set humidity Hs2, the process proceeds to step S10. In step S9, it is judged whether or not the upper limit execution time Tmax2 has passed. Then, 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 dehumidification project is completed, the third dehumidification process from step S10 to step S13 is executed. Specifically, in step S10, the switching 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 S11, it stands by until the lower limit execution time Tmin3 elapses. Next, in step S12, it is judged whether or not the detected humidity H caused by the humidity sensor 801 is lower than the set humidity Hs3. Then, when the detected humidity H is not lower than the set humidity Hs3, the process proceeds to step S13, and when the detected humidity H is lower than the set humidity Hs3, the process proceeds to step S14 of Fig. 14B. In step S13, it is judged whether or not the upper limit execution time Tmax3 has passed. Then, when the upper limit execution time Tmax3 has not elapsed, the process returns to step S12, and when the upper limit execution time Tmax3 has elapsed, the process proceeds to the step of FIG. 14B. S14.

As shown in FIG. 14B, when the third dehumidification project is completed, the completion of the process from step S14 to step S15 is performed. Specifically, in step S14, the switching 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, until the lower limit execution time Tmin3 has elapsed, and the lower limit execution time Tmin3 has elapsed, the process proceeds to step S16.

When the completion of the project is completed, the cooling (non-heating) process from step S16 to step S18 is performed. Specifically, in step S16, the switching elements 259a and 259b are turned off, the operation of the PTC heaters 251A to 251C is stopped, and the heater 250 is set to an unheated state. Next, in step S17, it waits until the body cooling time Tcd (for example, 3 minutes) has elapsed. Then, when the body cooling time Tcd has elapsed, the two-axis motor 490 is stopped in step S18, and the dehumidification process by the energy saving mode is ended.

In this way, the dehumidifier 1 can reduce the output of the heater 250 when the operation of promoting the drying is performed by using only a large amount of air to be blown even when the temperature is low, so that the power consumption can be suppressed and energy can be saved. Further, drying is carried out, and if it is difficult to dry only by the wind, the output of the heater 250 is raised to raise the temperature of the air to be blown. Therefore, the clothes to be dehumidified, that is, the clothes do not remain in the semi-dry portion, and can be sufficiently dried. In particular, the heater control of the dehumidification process ends after the execution of the completion of the high output of the heater 250. Moreover, the final completion of the present embodiment is performed until The preset setting time Tfin is set. Therefore, even in a situation where the room (space) of the clothes type is narrow, the semi-dry portion does not remain, and it can be surely dried.

(Second embodiment)

Fig. 15 is a view showing an energy saving mode (automatic dehumidification process) of the dehumidifier 1 according to the second embodiment. In the second embodiment, depending on the setting criteria (the set humidity Hs and the execution time Tmin, Tmax), not only the output of the heater 250 but also the amount of air supplied to the air fan 400 is changed, unlike the first embodiment. . Specifically, in the first dehumidification process, moisture is released from the clothes, and the humidity of the process air reaches the upper limit, and the air volume is maximized. After that, the air volume is gradually lowered after the air volume is reduced to the minimum level. Moreover, when shifting to the second dehumidification project, the amount of air blown by the process air fan 400 is similarly reduced to a minimum, and then gradually increases. In this way, in addition to the same actions and effects as those of the first embodiment, it is possible to control the dry state of the clothes.

Further, the dehumidifier 1 of the present invention is not limited to the structure of the above embodiment, and various modifications can be made.

For example, in the above-described embodiment, the output of the heater 250 is gradually increased from the initial stage to the end after the start of the dehumidification process (weak→medium→strong→strong), but the stepwise heater control of the present invention is Not limited to this configuration.

Specifically, in the case of determining the structure of the stepwise rise of the present invention, the project to be judged is to stop the output of the heater 250. Except for the non-heating project, only the work for operating the heater 250 is set. Further, when the dehumidification works set to the same output are continuously executed (for example, weak to weak), the works are treated as a dehumidification project. Moreover, when the execution time of the dehumidification project is short and does not affect the degree of dehumidification (drying) of the clothes, the dehumidification process is substantially absent.

In other words, when the first dehumidification project in which the output is set to the weak setting (first output) and the second dehumidification project in which the output is set to the middle (second output) are executed, the non-heating process for stopping the output is executed ( Since the weak → stop → medium) does not include a non-heating process, it is included in the present invention in which the output is gradually increased.

In addition, after setting the output to the middle setting, the output is set to the weak setting, and then the output is set to the strong setting (medium → weak → strong), and the first dehumidification project is set to the weak setting (first output). Thereafter, since the second dehumidification project is set to have a higher output than the first output, the operation method is included in the present invention in which the heating means is raised. Moreover, when the execution time of the weakly set dehumidification project is short and does not affect the degree of dehumidification (drying) of the clothes, the weakly set dehumidification project is substantially absent (medium→strong), so the output is set to medium (the After the first dehumidification process of the 1st output, the second dehumidification project is set to be stronger than the first output (second output). Therefore, the operation method is also included in the present invention for increasing the output.

In addition, after the output is set to a weak setting, the output is set to a strong setting, and then the output is set to medium setting (weak → strong → medium), and the first dehumidification project is set to the weak setting (first output). After that, the second dehumidification project has a strong setting (second output) that is higher than the first output. Therefore, the operation method is included in the present invention in which the heating means is raised. Moreover, when the execution time of the strongly set dehumidification project is short and does not affect the degree of dehumidification (drying) of the clothes, the dehumidification project that is strongly set is substantially absent (weak → medium), so the output is set to a weak setting (the first) After the first dehumidification process of the 1st output, the second dehumidification project is set to be higher than the first output (second output). Therefore, the operation method is also included in the present invention for increasing the output.

Further, the present invention is not limited to a structure in which the output of the heater 250 is gradually increased (weak → medium → strong), and includes a weak setting (first output) to a strong setting (a higher output than the first output). 2 output) construction. Further, the output of the heater 250 may be weak, medium, weak, or strong, and may be included in the present invention if there is a project to increase the output of the heater 250.

Further, in the above embodiment, the final stage of the heater control is to set the heater 250 to the highest output (100%), but it is also possible to set the medium (66%) output. Further, the output of the heater 250 is not limited to three stages, and may be two stages or four stages or more. Further, the heater 250, which is a heating means, is not limited to the structure in which three PTC heaters 251A to 251C are used, and the coil heater may be used to change the energy rate period.

Further, in the above-described embodiment, after the start of the energy saving mode (dehumidification process), the control for operating the fans 400 and 450 by the two-axis motor 490 and the control for operating the heater 250 are simultaneously performed, but the heater is not provided. After the operation of 250 and the fans 400 and 450 are operated, the control of the heater 250 may be performed. Further, in the energy saving mode, the number of rotations of the fans 400 and 450 is set to a strong setting. However, it is also possible to set the middle and the weak, and the number of rotations may be changed during the processing.

In the dehumidifier 1 of the present embodiment, for example, the moisture of the clothes for drying clothes is used as a target for dehumidification, and the indoor air for drying indoors is also used as a target for dehumidification, and both of them are achieved. In other words, the dehumidifier 1 of the present invention includes a dryer for drying the clothes to be dehumidified and the inside of the room.
