[Industrial application fields]
The present invention relates to an electrical device having a dehumidifying function.
[0002]
[Prior art]
FIG. 9 is a cross-sectional view showing a conventional dehumidifier. In FIG. 9, reference numeral 101 denotes an evaporator provided in an air passage 115 on the downstream side of the suction port 102, and a condenser 103 is provided downstream thereof. Further, a blower fan 105 is provided downstream thereof, and an air outlet 107 having a wind direction plate 104 is provided. The evaporator 101 is received by a drain pan 109 having a drain port 108, and a tank 110 is installed below the drain port 108. On the other hand, the evaporator 101 and the condenser 103 are connected by a refrigerant pipe to a compressor 112 mounted on the bottom plate 111 to constitute a refrigerant circuit. A control circuit 114 that controls the blower fan 105 and the compressor 112 is provided above the compressor 112.
[0003]
Next, the operation will be described. When the compressor 112 starts to be energized by the control circuit 114, the high-temperature and high-pressure refrigerant gas flows into the condenser 103, and the condenser 103 is kept at a high temperature. The control circuit 114 energizes the blower fan 105, and the refrigerant gas in the condenser 103 is cooled and condensed by the intake air 113 sucked from the suction port 102, and becomes a high-temperature and high-pressure refrigerant liquid. After exiting and further passing through the capillary tube, a low-temperature and low-pressure gas-liquid mixed state is obtained and enters the evaporator 101. The vapor-liquid mixed state of the evaporator 101 is heated by the suction air 113 to evaporate, becomes low-pressure refrigerant gas, and is sucked into the compressor 112. At the same time, the intake air 113 is condensed by being cooled by the evaporator 101, is received by the drain pan 109, further falls into the tank 110 through the drain port 108, and is stored in the tank 110.
[0004]
The tank 110 is provided with a water detection device 116 that detects the water level in the tank. When the water level in the tank reaches a certain position, the water detection device detects and stops the operation.
[0005]
Thus, the cooled intake air 113 passing through the evaporator 101 is heated by passing through the condenser 103, and is dehumidified as air is discharged from the outlet 107 along the wind direction plate 104 by the blower fan 105. The

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. In the following description based on the drawings, an example of a portable dehumidifier will be described as a specific example of an electric device according to the present invention.
[0026]
FIG. 1 is a front view of a dehumidifier 1 as an example of the present invention as viewed from the front. FIG. 2 is a plan view of the dehumidifier 1 shown in FIG. 1 as viewed from above. FIG. 3 is a partially enlarged view showing in detail a portion of the operation panel 4 of the dehumidifier 1 shown in FIG.
[0027]
The dehumidifier 1 shown in FIG. 1 to FIG. 3 is provided with the same members as the conventional dehumidifier described based on FIG. 9 inside the main body so that it can function as a dehumidifier. . That is, an evaporator, a condenser (reheater), and a compressor are provided inside the main body of the dehumidifier 1, and the evaporator and the condenser are received by a drain pan, and the tank 3 is provided below the drain port provided in the drain pan. Is provided. And an evaporator and a condenser are connected with a compressor by refrigerant piping, and a refrigerant circuit is constituted.
[0028]
The dehumidifier 1 includes a filter, a motor, and a sirocco fan inside the main body. When the sirocco fan is rotationally driven by the motor, air is sucked into the main body through the filter from the suction portion that occupies the substantially upper half of the rear frame. The sucked air is cooled by an evaporator constituting a refrigeration cycle together with a compressor, and moisture is condensed to dehumidify. The condensed moisture is collected in the drain tank 3. Since the temperature of the dehumidified dry air is low, it is heated by a condenser (reheater), returned to the temperature before dehumidification, discharged into the room from the blowout port 2, and dehumidifies the room.
[0029]
The drain tank 3 is provided with a float switch 19 for detecting a water level due to the moisture condensed and collected in the drain tank 3. This float switch constitutes a water level detection means. The water level detecting means is not limited to the float switch, and any means that can detect the water level in the tank 3 may be used. For example, a level sensor or the like may be used.
[0030]
The mounting state of the drain tank 3 can be detected by a tank mounting sensor 17. That is, when the drain tank 3 is correctly mounted at the position where the dehumidifier 1 should be inserted, the tank mounting sensor outputs a signal (ON signal) indicating that the tank 3 is mounted.
[0031]
On the other hand, when the drain tank 3 is not properly attached to the dehumidifier 1, for example, when the drain tank 3 is removed from the dehumidifier 1, the tank attachment sensor indicates that the tank is not correctly attached. (OFF signal) is output. This tank mounting sensor constitutes tank mounting detection means.
[0032]
An operation panel 4 shown in FIGS. 2 and 3 is provided on the upper surface 5 of the dehumidifier 1. As shown in FIG. 3, the operation panel 4 is provided with an operation switch 10, an operation changeover switch 11, and a turn-off timer switch 12. These switches constitute an operation unit.
[0033]
The operation switch 10 is for starting / ending the operation by turning on / off (ON / OFF) the power supply of the dehumidifier 1.
By operating this, the operation changeover switch 11 can select the operation of the dehumidifier 11 between the standard mode and the air clean mode. Each time the operation changeover switch 11 is pressed, “standard” → “air clean” → “standard” can be selected in order.
[0034]
Then, it can be confirmed by lighting of the corresponding display lamps 21a ("standard") and 21b ("air clean") which is selected by the operation of the operation changeover switch 11. The display lamps 21 a and 21 b constitute a display unit that displays the operation state of the dehumidifier 1. The standard mode set by operating the operation changeover switch 11 is a basic mode for performing the dehumidifying operation.
[0035]
The cut-off timer switch 12 is for selecting an operation mode other than the one operation mode among the modes prepared as the auto-cut operation mode. This other operation mode is an operation mode in which the displayed time T1 can be selected from the auto cut operation modes as a clue.
[0036]
In the dehumidifier 1, three modes of the first other operation mode, the second other operation mode, and the third other operation mode can be selected by the turn-off timer switch 12. The three other operation modes differ in the set time limit.
[0037]
In the dehumidifier 1, three types of 2 hours, 4 hours, and 8 hours are displayed as the time display T 1 for selecting another operation mode by the turn-off timer switch 12, while checking the display T 1. Any one of the first other operation mode to the third other operation mode can be selected.
[0038]
In this example of the dehumidifier 1, every time the off timer switch 12 is pressed, “2” → “4” → “8” → “cancel” → “2” can be selected in order. Then, which of the other operation modes is selected by the turn-off timer switch 12 is indicated by the display lamps 22a ("2"), 22b ("4"), 22c ("" corresponding to the selected mode. 8 ”) can be confirmed. The display lamps 22a, 22b, and 22c constitute a display unit that displays the operation state.
[0039]
Moreover, in this dehumidifier 1, in the state set to the standard mode for performing the dehumidifying operation, the operation switch 10 and the turn-off timer switch 12 are pressed simultaneously and continuously without stopping the operation automatically. A continuous operation mode in which the dehumidifying operation is performed and an automatic cut operation mode in which the operation is stopped with the set time limit as an upper limit can be switched.
[0040]
When the operation switch 10 and the turn-off timer switch 12 are pressed at the same time while operating in the continuous operation mode, it is possible to switch to the auto cut operation mode. On the other hand, when the operation switch 10 and the turn-off timer switch 12 are pressed simultaneously while operating in the auto cut operation mode, the operation mode can be switched to the continuous operation mode.
[0041]
Moreover, in this dehumidifier 1, when it is in the state of an auto cut operation mode and the other operation mode by the said cut timer switch 12 is not selected, it sets to one operation mode. And when setting to one operation mode, time limit T0 is set as an upper limit of the operation time which stops an operation | movement.
[0042]
The operation panel 4 is provided with a display board (not shown) as a part of the display unit. The display board displays a message that prompts the user for an operation and asks for confirmation, and can also display which operation mode is set by the user's operation in response to the inquiry. .
[0043]
The operation panel 4 is also provided with an input means for inputting an inquiry to the user displayed on the display board.
The operation panel 4 is provided with an “8 hour lamp” (not shown) as a part of the display unit. This “8-hour lamp” is used when the operation of the third other operation mode corresponding to the display of the time “8” is terminated by the off timer switch 12 or in the operation mode of the auto cut operation mode. Lights when T0 operation is finished.
[0044]
The dehumidifier 1 is provided with a humidity sensor 18 (not shown in FIGS. 1 to 3), and the humidity of the surrounding space to be dehumidified by the dehumidifier 1 can be detected by the humidity sensor.
[0045]
Further, the dehumidifier 1 is provided with a blower (blower fan) 29, and the air taken into the main body by the blower 29 and dehumidified is sent out from the outlet 2 to the outside.
[0046]
Next, the control block of the dehumidifier 1 is demonstrated based on FIG. FIG. 4 is a block diagram illustrating a control block of the dehumidifier 1.
When the operation switch 10, the operation changeover switch 11, and the turn-off timer switch 12 described above are operated, an ON / OFF (on / off) signal accompanying the operation of each switch is sent to the control unit 25 via the switch determination means 15. Entered. As a result, the contents of the operation on each of the switches 10, 11, and 12 can be determined by the control unit.
[0047]
In addition, signals output from each of the tank mounting sensor 17, the humidity sensor 18, and the float switch 19 are input to the control unit 25 via the determination unit 16. Thereby, the mounting state of the tank 3, the humidity data around the dehumidifier 1, and the water level data in the tank 3 are input to the control unit 25.
[0048]
The control unit 25 includes control means and timekeeping means. Thereby, the time measuring means can obtain time data. The time data obtained by the time measuring means is input to the control means, and the time lapse data after the start of the dehumidifying operation in the auto cut operation mode can be obtained by the control means.
[0049]
The control means controls the operating state of the dehumidifier 1. The control means includes calculation means and storage means necessary for controlling the operation of the dehumidifier 1. The control means can be configured by a microcomputer that stores measured data and programs and performs arithmetic processing based on the stored contents. In addition, the storage unit can be configured by a RAM, a ROM, or the like as necessary, and can also be configured by using a nonvolatile memory (EEPROM).
[0050]
In addition, the control means stores an operation control program containing the procedure for operating the dehumidifier 1. In the operation control program, the time data obtained by the time measuring means is read, and the operation control program is accompanied by the operation of each switch 10, 11, 12 input from the switch determining means 15 to the control unit 25. Based on the signal, the contents of the operation on these switches can be discriminated.
[0051]
Thereby, the control means can switch the driving | running state which performs a dehumidification driving | operation between continuous operation mode and auto cut operation mode, if switch 10 and 12 are operated simultaneously. Further, the control means can set one of the auto cut operation modes or one of the first to third other operation modes according to the operation of the switch.
[0052]
The control means also stores the following data necessary for the automatic cut operation mode. Stored is a time limit T0 of one operation mode of the auto cut operation mode, a display time T1 for selecting another operation mode, and a shortened time data α for shortening an actual operation time for the T1.
[0053]
The operation control program stored in the control means receives data based on the signals of the tank mounting sensor 17, the humidity sensor 18, and the float switch 19 input to the control unit 25 from the determination means 16. The mounted state, the humidity around the dehumidifier 1 and the water level in the tank 3 can be determined.
[0054]
The control means outputs various operation control signals as the operation control program is executed. The control means outputs an operation control signal to the dehumidifying drive circuit 26 to control operations of the evaporator, the compressor, the condenser, and the like, and controls the execution of the refrigeration cycle. The control means controls the operation of the blower 29 by outputting an operation control signal to the blower drive circuit 27. In this way, the control means can execute the refrigeration cycle according to the selected operation mode, and can also operate the blower 29.
[0055]
Further, the control means outputs an operation control signal to the display drive circuit 28, so that it corresponds to one of the display units 21a, 21b, 22a,... According to the set operation mode and operation status. Make things light up.
[0056]
Next, the example which operates the dehumidifier 1 demonstrated above is demonstrated based on FIG. FIG. 5 is a flowchart showing a procedure for operating the dehumidifier 1. First, the operator (or user) of the dehumidifier 1 inserts the plug of the main body and connects the dehumidifier 1 to a power source.
[0057]
Then, the operation switch 10 is set to “ON” by the operation of the operator (S100). Thereby, the execution of the operation control program stored in the control unit 25 is started. Next, the operation changeover switch 11 is operated to select the standard mode (hereinafter referred to as “dehumidifying operation”) to start the operation in the standard mode (S101).
[0058]
Next, the operator operates the off timer switch 12 to select a desired display from the displayed time T1 and select one of the other operation modes (for example, an operation mode “8 hours displayed as T1” 8 ”) is set (S102). Next, in the dehumidifier 1, it is determined whether another operation mode is set by the turn-off timer switch 12 (S103).
[0059]
When it is determined that another operation mode is set by the turn-off timer switch 12 (S103, Yes), a time (T1-α) shorter than the selected time display T1 is set as the actual time limit, and the dehumidifying operation is performed. Is started (S104).
[0060]
Next, when the set time limit (T1-α) elapses after the dehumidifier 1 starts the dehumidifying operation, the dehumidifying operation is stopped (S105), and the “8-hour lamp” on the display blinks and dehumidifies. The end of driving is notified (S106).
[0061]
On the other hand, when it is determined in S103 that the other operation mode by the off timer switch 12 is not set (S103, NO), the dehumidifying operation time limit is set to T0 time and the dehumidifying operation is started (S107). ).
[0062]
Next, when the time limit T0 has elapsed since the start of the dehumidifying operation, the dehumidifying operation is stopped (S108), and the “8-hour lamp” on the display unit blinks to notify the end of the dehumidifying operation (S106).
[0063]
The time limit T0 set in S107 is stored in the control unit 25 in advance, but is preferably set to be longer than the time display T1 for selecting another operation mode by the turn-off timer switch 12. . When 8 hours are displayed as T1, it is preferable to select a time of about 12 hours as the time limit T0.
[0064]
Further, regarding the shortened time data α for shortening the time limit actually set with respect to the time T1 displayed in correspondence with the operation mode by the above-mentioned off timer switch 12, T1 is 2 hours, 4 hours, or 8 hours. In some cases, a time of about 30 minutes or 1 hour can be selected. Further, this α may be set to 0 hour. In this case, the displayed time T1 matches the actually set time limit.
[0065]
The time T1 used as a clue for selecting another operation mode is stored in the control unit 25 in advance, but is shorter than the time from the start of the dehumidifying operation until the tank 3 is full. preferable. As a result, the time limit for the other operation modes set based on the time T1 can be set to the time before the tank 3 is full. Therefore, when the operation is performed in another operation mode, the operation is performed before the tank 3 is full. Can be terminated. Thereby, the safety | security at the time of drive | operating by another operation mode can be made more reliable.
[0066]
Next, another operation example for operating the dehumidifier 1 will be described with reference to FIG. FIG. 6 is a flowchart showing an operation for detecting that the water level in the tank has reached full water.
First, the operator of the dehumidifier 1 inserts the plug of the main body and connects the dehumidifier 1 to the power source.
[0067]
Then, the operation switch 10 is set to “ON” by the operation of the operator (S200). Thereby, the execution of the operation control program stored in the control unit 25 is started.
[0068]
Next, the operation changeover switch 11 is operated to select the standard mode (“dehumidifying operation”) to start the operation in the standard mode, but the operation mode is not selected by the off timer switch 12 (S201). As a result, the dehumidifier 1 is set to one of the automatic cut operation modes, the time limit is set to T0 (S201), and the dehumidification operation is started (S202).
[0069]
Next, when the water level detection means detects that the inside of the tank 3 has reached the full water level during the dehumidifying operation, the water level display lamp 23 of the display unit notifies the user.
The operator confirms the notification of the water level indicator lamp 23 to stop the operation of the dehumidifier 1 and remove the water from the tank 3 after removing the tank 3 from the dehumidifier 1, and then dehumidify the tank 3 again. It is mounted on the machine 1 (S203).
[0070]
Next, in the dehumidifier 1, whether or not the water in the tank 3 has been discharged depends on whether or not the signal indicating the mounting state of the tank 3 by the tank mounting detection means has changed from ON (ON) to OFF (OFF). Determination is made (S204).
[0071]
When it is detected that the signal of the tank mounting detection means has changed from ON to OFF (S204, Yes), it is determined whether or not the tank 3 is mounted again. Is determined by whether or not the signal according to has changed from OFF to ON (S205). If it is not detected in S205 that the tank 3 is mounted (S205, NO), S205 is repeated until the mounting of the tank 3 is detected.
[0072]
When it is detected in S205 that the tank 3 is mounted (S205, Yes), the measurement of the time elapsed in the previous operation by the time measuring means is reset, and the dehumidifying operation is performed while measuring the time limit T0 from the beginning. Start (S206), and S204 and subsequent steps are repeated.
[0073]
On the other hand, in S204, when it is not detected that the signal indicating the mounting state of the tank 3 by the tank mounting detecting means is changed from ON (ON) to OFF (OFF) (S204, NO), the time limit T0 has elapsed. Is determined (S207). When it is determined that the time limit T0 has elapsed (S207, Yes), the operation is stopped. On the other hand, when it is not determined in S207 that the time limit T0 has elapsed (S207, NO), S204 and subsequent steps are repeated.
[0074]
In the example of the operation described above, when it is detected that the tank is full and the tank 3 is removed and emptied, the tank 3 is attached again and the dehumidifying operation is resumed. The measurement of the elapsed time is reset, and the time limit T0 is measured again from the beginning. As a result, the passage of the time limit can be measured in correspondence with the state in the tank 3, so that it is determined that the time limit has passed sufficiently earlier than the tank 3 is full, and the dehumidifier is stopped. Can be prevented.
[0075]
Next, still another operation example for operating the dehumidifier 1 will be described with reference to FIG. FIG. 7 is a flowchart of an operation for switching from the automatic cut operation mode to the continuous operation mode.
[0076]
First, the operation is started in one operation mode of the auto cut operation mode in which the time limit is set to T0 (12 hours) without operating the dehumidifier 1 and operating the cut-off timer switch 12 (S300).
[0077]
Next, the operator performs an operation of simultaneously pressing the operation switch 10 and the turn-off timer switch 12 as an operation for canceling the automatic cut operation mode (S301).
[0078]
Next, a message asking the operator whether or not to cancel the auto cut operation mode is displayed on the display unit (S302). When the operator inputs Yes (S302, Yes), the auto cut operation mode is set. The setting is canceled and the continuous operation mode is set in which the vehicle is continuously operated without being automatically stopped (S303).
[0079]
On the other hand, when the operator inputs NO (No) in response to the inquiry in S302 (S302, NO), the automatic cut operation mode is set in which the operation is stopped within the set time limit (S304).
[0080]
On the other hand, although the operation procedure is not shown in FIG. 7, when it is desired to switch from the continuous operation mode to the auto cut operation mode, the operation switch 10 and the cut timer switch 12 are simultaneously pressed to switch to the auto cut operation mode. Can do.
[0081]
When operating in the auto-cut operation mode described above, even if the water level detection means such as the float switch for detecting the water level in the tank 3 does not operate and the operation is not stopped, the time limit (T0 or ( Since the operation can be surely stopped at T1-α)), it is possible to prevent water from overflowing from the tank 3 and improve safety.
[0082]
In addition, as the time limit for the auto-cut operation mode described above, it is desirable to select a time during which the water level detection means can stop the operation before detecting the full water level in the tank 3.
[0083]
Next, still another operation example for operating the dehumidifier 1 will be described with reference to FIG. FIG. 8 is a flowchart showing an operation of storing the measurement data obtained during the previous driving and setting the time limit based on the measurement data.
[0084]
First, the dehumidifier 1 is operated and the deactivation timer switch 12 is not operated, and the dehumidification operation (A) is started in one operation mode of the auto cut operation mode in which the time limit is set to T0 (12 hours) (S400). ).
[0085]
Next, the dehumidifying operation is performed until the tank 3 is full and the operation is stopped (S401). The humidity state (B) when the dehumidifying operation (A) is performed and the tank 3 is full. Data of the time until detection is stored and saved in a microcomputer or a non-volatile memory (EEPROM or the like) constituting the control means (S402).
[0086]
Next, the humidity before starting the current dehumidifying operation is detected by the humidity sensor (S403). Then, the humidity data before the start of the current operation obtained in S403 is compared with the humidity data obtained during the previous operation obtained in S402 (S404).
[0087]
When the humidity before the start of the current operation is lower than the humidity during the previous operation (S400) (Yes in S404), the same time limit as the time limit T0 of the auto cut operation mode (A) in which the previous operation was performed is set. Start operation in auto cut mode. If the humidity before the start of the current operation is higher than the humidity at the previous operation (S400) (S404, NO), it is determined whether the humidity before the start of the current operation is 80% or more (S406).
[0088]
If the humidity before the start of the current operation obtained in S403 is not 80% or more (S406, NO), the time limit is shorter than the time limit T0 of the auto cut operation mode (A) during the previous operation (S400). Is set, and the operation is started in the auto cut operation mode (S407). For example, if the time limit T0 in the auto-cut operation mode (A) at the previous operation (S400) is 12 hours, the time limit for performing this operation can be set to 10 hours.
[0089]
On the other hand, when the humidity before the start of the current operation obtained in S403 is 80% or more (S406, NO), it is extremely shorter than the time limit T0 of the auto cut operation mode (A) in the previous operation (S400). The time limit is set and the operation is started in the auto cut operation mode (S408). For example, if the time limit T0 in the auto cut operation mode (A) at the previous operation (S400) is 12 hours, the time limit for performing the current operation can be set to 8 hours.
[0090]
As in the operation example described with reference to FIG. 8, the humidity measured during the previous operation and the time until the tank 3 is full are stored, and the current operation is limited based on this measurement data. When the time is set, it is possible to operate by setting a more appropriate time limit corresponding to the surrounding situation where dehumidification is performed. Thereby, the usability of the dehumidifier 1 can be improved.
[0091]
In the above description with reference to FIG. 1 to FIG. 8, an example of a dehumidifier has been described as an electrical apparatus according to the present invention. That is, an example of a dehumidifier that takes outside air into the main body and dehumidifies it, and then sends the dehumidified air to an external space by a blower has been described.
