Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a dehumidifier that dehumidifies a room and supplies the low-humidity air to clothes suspended in the room to dry the clothes.
[0002]
[Prior art]
Conventionally, this type of dehumidifier has a configuration shown in FIGS. 12 and 13.
[0003]
As shown in the figure, during normal indoor dehumidifying operation, the automatic dehumidifying operation set by the automatic dehumidifying switch 102 of the operation unit 101 is selected, and the desired humidity is set by the humidity setting switch 103. The control unit (not shown) compares the indoor current humidity by the humidity sensor with the set humidity set by the humidity setting switch 103 and performs an appropriate dehumidifying operation.
[0004]
Further, in the clothes drying operation set by the clothes drying switch 104, the setting of the continuous operation with the dehumidifying capacity as the maximum output is generally set. In addition to this operation setting, the operation is stopped after a predetermined time by operating the switch timer switch 105. Some can be done.
[0005]
Hereinafter, the operation of the clothes dryer will be described with reference to the flowchart of FIG.
[0006]
First, if there is a switch input in STEP 1, the process proceeds to STEP 2. If this switch input is not a clothes drying switch, the operation mode specified by the input switch is executed, and if it is a clothes drying switch, the process proceeds to STEP 3. And then dry clothes.
[0007]
Next, when there is an operation stop switch input in STEP 4, the operation is stopped in STEP 5. When there is no input of the operation stop switch, the process proceeds to STEP 6 to determine the setting of the timer, and when there is no setting, the process proceeds to STEP 3 and the clothes drying operation is continued. If the timer is set, the process proceeds to STEP 7 to determine the elapsed time of the timer. If the timer set time has elapsed, the operation proceeds to STEP 5 to stop the operation, and if the set time has not yet elapsed, the clothes drying operation is continued in STEP 3.
[0008]
[Problems to be solved by the invention]
In such a conventional dehumidifier, if the user forgets to stop the operation for drying clothes in continuous operation, or if the timer is not set even if there is a timer, even after the clothes have dried There is a problem that the useless dehumidification operation is continued, resulting in excessive dehumidification and waste of power consumption, and it is required that the operation of the dehumidifier is automatically stopped when the clothing drying is finished. .
[0009]
The present invention solves such a conventional problem. When a user selects a clothing drying operation, the device automatically starts an operation suitable for clothing drying, and automatically operates when a necessary drying time elapses. The purpose is to stop operation.
[0010]
In addition, if the indoors when the clothes drying operation is performed are in a low humidity condition, the clothes are also easily dried.Therefore, a standard timer time set in advance causes a wasteful dehumidifying operation after the clothes are dried. When the indoor humidity is low, it is required to shorten the drying time of clothes.
[0011]
An object of the present invention is to solve such a conventional problem, and when the indoor humidity is low, an object of the present invention is not to perform a wasteful dehumidifying operation after the clothes are dried.
[0012]
In addition, if clothing is sufficiently dried and the clothing is left in a state of being stopped after completion of the drying operation by the timer, there is a problem that the dried clothing absorbs moisture in the atmosphere, and this re-absorption is economically prevented. It is requested.
[0013]
The present invention solves such a conventional problem, and aims to economically prevent reabsorption of clothes after the operation of drying clothes is completed.
[0014]
In addition, when clothing drying by the timer is stopped, if the surrounding atmosphere is in a high humidity state, the room gradually becomes in a high humidity state, and there is a problem that it is difficult to prevent re-absorption of clothing, even when the atmospheric humidity is high There is a need to prevent re-absorption of clothing.
[0015]
SUMMARY OF THE INVENTION The present invention solves such a conventional problem, and an object of the present invention is to more effectively prevent re-absorption of clothes by keeping the ambient humidity after drying the clothes at an appropriate humidity.
[0022]

[0028]
【Example】
Below, with reference to the accompanying drawings embodiments of the present invention.
[0029]
(Reference Example 1)
As shown in FIGS. 1 to 4, an operation unit 2 is provided on the top surface of the main body 1, and the operation unit 2 has a clothing drying switch 4 for selecting a clothing drying mode or a dry keeping operation mode, and this clothing drying unit. A dry LED 6 and a dry keep LED 7 for displaying the operation mode selected by the switch 4 are arranged. Further, a timer switch 5 for selecting a timer, a timer time setting and a remaining time display by operating the timer switch 5 are displayed. An LED 8 for displaying numbers is provided.
[0030]
As shown in the block diagram of FIG. 4, the control unit 9 in the main body 1 is provided with a microcomputer 10, and the microcomputer 10 is provided with timer control means 11 for performing timer time control when setting a timer. ing. Further, the control unit 9 is provided with a dehumidification control means 14 for controlling the driving of the dehumidifying device 13 and a blowing control means 16 for controlling the driving of the blowing device 15.
[0031]
The main operation in the above configuration will be described. As shown in the flowchart of FIG. 4, STEP 11 and STEP 12 determine the switch input and the type of the input switch. If the input is the clothes drying switch 4, STEP 13 Then, the timer control means 11 sets a timer time of 3 hours as a fixed timer time. In STEP14, the drying LED 6 is turned on and the clothing drying operation is started with the dehumidification amount and the air volume as the maximum output, and the timer operation for 3 hours is started at the same time. In STEP15, the timer control means 11 determines the elapsed time of the timer, and when 3 hours have elapsed, the process proceeds to STEP16 and stops operation.
[0032]
If the clothes to be dried are suspended above the outlet of the dehumidifier and the clothes drying operation is selected as described above, a 3-hour timer is automatically set with the maximum dehumidifying capacity, and the clothes drying ends normally. The operation will be stopped after an hour. That is, useless dehumidifying operation is eliminated and energy-saving operation can be performed.
[0033]
As shown in the characteristic diagram of FIG. 5, with respect to the characteristics of the drying time and the dryness, it can be understood that if the dryness is 97% or more, the drying of the clothes is completed, and the drying is completed within 3 hours in the normal use state. . The dryness is a ratio of the standard weight in the normal dry state of the clothes to the weight of the clothes to be dried, and the dryness of the clothes when starting to dry the clothes is 70%.
[0034]
( Reference Example 2)
In this reference example, the same components as those in the reference example 1 are assigned the same reference numerals and detailed description thereof is omitted. As shown in FIGS. 2 to 4, 7, and 8, a humidity sensor 3 that detects indoor humidity is provided inside the side surface of the main body 1, and the detected humidity detected by the humidity sensor 3 is preset in the microcomputer 10. Comparison determination means 12 is provided for comparing and determining the humidity value 40% (first threshold value). When the comparison determination means 12 determines that the humidity detected by the humidity sensor 3 is greater than the preset humidity 40%, the timer control means 11 sets a shortened timer time (2 hours) shorter than the fixed timer time (3 hours). The clothes are dry-dried.
[0035]
Main operations in the above configuration will be described with reference to the flowchart of FIG. First, Steps 11 to 14 perform the same operation as in Example 1, and start a timer operation for 3 hours in STEP14. In STEP 205, the humidity sensor 3 detects the current humidity in the room, and in STEP 206, the comparison / determination means 12 compares the humidity 40% (first threshold value) preset in the microcomputer 10 with the humidity detected in STEP 205. If it is determined that it is 40% or less, the process proceeds to STEP 207. If the elapsed time is 2 hours, the operation is stopped in STEP 208. If the elapsed time is not 2 hours, the clothes drying operation and the humidity detection are continued. .
[0036]
If it is determined in STEP 206 that the humidity is 40% or more, the process proceeds to STEP 209, the clothes drying operation is continued, and the elapsed time of the timer is determined in STEP 210. At this time, when 3 hours have elapsed, the operation is stopped at STEP 211, and when 3 hours have not elapsed, the operation proceeds to STEP 209 and the clothes drying operation is continued.
[0037]
As shown in FIG. 7, the relationship between the atmospheric humidity and the drying of clothing takes about 3 hours until the dryness of the clothing reaches 97% when the ambient humidity is 90% and the ambient temperature is 10 ° C. It can be seen that 40% is dry within 2 hours.
[0038]
As described above, if the indoor humidity is constantly kept at 40% or less until the elapsed time of the timer time automatically set by performing the clothes drying operation has passed 2 hours, the clothes drying is efficient. Since it is performed, it can be judged that it is sufficiently dry within 2 hours and the operation can be stopped. Therefore, when the atmospheric humidity is low, it is possible to shorten the drying time and to save useless drying operation. In this embodiment, the humidity is set to 40% as the first threshold value, but it may be set to a humidity value other than 40% depending on use conditions.
[0039]
(Example 1 )
In the present embodiment, the same components as those in Reference Example 1 are denoted by the same reference numerals and detailed description thereof is omitted.
[0040]
As shown in FIGS. 2 to 4, 8, and 9, the microcomputer 10 can operate the air blower 15 for 9 hours after completion of the timer operation for 3 hours.
[0041]
In the above configuration, main operations will be described with reference to the flowchart of FIG. The steps 11 to 14 are the same as those in the first embodiment, and the clothes drying operation of the timer for 3 hours is started in STEP14. In STEP 305, it is determined whether or not the timer time setting has been changed by inputting the OFF timer switch 5, and if there is no change in the timer setting, the process proceeds to STEP 310, where the timer elapsed time is determined by the timer control means 11 and 3 hours have elapsed. , The clothes drying operation is stopped, the dehumidifying control means 14 stops the dehumidifying device 13, and the air blowing control means 16 performs the air blowing operation by the air blowing device 15. Next, the timer control means 11 determines whether or not the time has elapsed since the start of the air blowing operation in STEP 312. When 9 hours have passed, the air blowing control means 16 stops the air blower 15 in STEP 313 and the operation is stopped. In STEP 309, when the set time has passed since the timer control means 11 determines the elapsed time of the change-off timer change setting, the process proceeds to STEP 311, and the blower control means 16 drives the blower device 15 to perform the blowing operation.
[0042]
That is, when the timer switch 5 is not set, the drying operation is a preset timer operation for 3 hours and the drying operation is performed. However, when the timer time is set by the timer switch 5, the drying operation is performed as shown in STEPs 306 to 309. The operation time can be changed arbitrarily. After the drying operation is finished due to the elapse of the timer time, the dehumidifying operation is automatically switched to the air blowing operation, and the clothing is in a moisture absorption preventing operation again. As shown in FIG. 9, the relationship between the moisture reabsorption of the clothes after the drying operation and the standing time is as follows. It can be seen that the degree is maintained.
[0043]
(Example 2 )
In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals and detailed description thereof is omitted. As shown in FIGS. 2 to 4, 7, and 8, when the drying keep operation is started after the clothes drying operation is finished, the microcomputer 10 detects the humidity detected by the humidity sensor 3 and the humidity set as the second threshold value. Comparison is made with 55%. When the detected humidity exceeds 55%, the dehumidifying operation is performed, and when the detected humidity is 55% or less, the air blowing operation is performed.
[0044]
In the above configuration, main operations will be described with reference to the flowchart of FIG. STEP 11 to STEP 309 are the same as those in the third embodiment, and STEP 410 and subsequent steps will be described. When 3 hours have passed in the determination of the timer elapsed time in STEP 410, the process proceeds to STEP 411, the clothes drying operation is stopped, and the dehumidifying control means 14 stops the dehumidifying device 13. In STEP 412, the humidity detection value by the humidity sensor 3 is compared with 55% (second threshold value) set in advance by the comparison / determination means 12. If the humidity is higher than 55%, the process proceeds to STEP 414, and if the humidity is low, the process proceeds to STEP 413.
[0045]
First, when the comparison / determination unit 12 determines low humidity and proceeds to STEP 413, the dehumidifying control unit 12 stops the dehumidifying device 13, and the air blowing control unit 16 controls the air blowing device 15 to perform the air blowing operation. When the comparison / determination unit 12 determines that the humidity is high and the process proceeds to STEP 414, the dehumidification control unit 12 switches the dehumidifying device 13 to an efficient indoor dehumidifying mode with low power consumption and performs a dehumidifying operation. Next, the process proceeds to STEP 415, where the timer control means 11 determines whether the time has elapsed since the start of the automatic dehumidifying operation. When 9 hours have elapsed, the operation is stopped at STEP 416. If 9 hours have not elapsed in STEP 415, the process returns to STEP 411, where the humidity sensor 3 detects the current humidity and the comparison determination means 12 performs a humidity comparison determination. Will continue.
[0046]
As described above, the re-moisture prevention operation after the completion of the drying operation is sufficiently effective in the air blowing operation in the normal humidity state, but in the high humidity state, the clothing easily re-absorbs moisture. The automatic dehumidifying operation is performed with the humidity of 55% as the second threshold value. As shown in FIG. 11, the relationship between the degree of drying after the drying operation in the high humidity and normal humidity conditions and the standing time is as follows. It is not very effective, and it can be seen that, when the humidity is about 55%, prevention of re-absorption of moisture in the air blowing operation is sufficiently effective as judged from the dryness.
[0050]
Further, a dehumidifying means and a blowing means provided in the main body, a control unit for controlling the operation of the dehumidifying means and the blowing means, and one of a plurality of operation modes provided on the main body surface are selected and operated. When the operation unit has an operation unit and the dry keep mode provided in the operation unit is selected, the control unit performs a timer operation with the dehumidifying unit and the air blowing unit as maximum outputs, and subsequently performs a dry keep operation as a dry operation. when the detected humidity of the humidity sensor is below a second threshold value during the keep operation is operated only said blowing means, when air blowing operation of the drying keep operation detected humidity of the humidity sensor is higher than a second threshold If the control unit is effectively prevented remoisturized after clothes drying by performing the dehumidifying operation in addition to the blowing operation, the dried clothes dehumidifier is effective can be kept reliably dry state is Hisage It can be.
