The present invention provides an air conditioner having at least an indoor fan and a compressor. An air conditioner (hereinafter referred to as an air conditioner) which performs an operation for drying the laundry dried indoors based on a command from an operation unit, for example, a remote controller (hereinafter referred to as a remote controller). It relates to a drying operation method of.

The air conditioner can normally be operated in the heating operation mode, the cooling operation mode, or the automatic operation mode, and selection means for selecting all the operation modes is provided in the remote controller. Recently, it has been proposed to add a dry operation mode for drying laundry hanging indoors again in these operation modes. The drying operation method proposed conventionally can be summarized as follows.

(1) In dry operation, operation is performed in the cooling operation mode or the heating operation mode in which the set temperature is automatically fixed at a specific value, and the operation stop of the compressor in the refrigerating cycle is the same as in normal cooling operation or heating operation. The air volume of the indoor fan is reduced.

(2) The blowing direction of the room, that is, the direction of the louver attached to the discharge port of the indoor unit, but in the same manner as in the normal heating operation, the louver in the heating and drying operation is fixed in the horizontal direction regardless of the operation or stopping of the compressor. · The louver in the dry operation is fixed in the downward direction.

(3) Monitoring status (indoor or outside air temperature is monitored as a minimum air flow operation to determine whether to perform cooling operation or heating operation without reaching the temperature for heating operation or heating operation. In the state of intermediate "judgment" operation, the louver direction is maintained horizontally until the air temperature of the indoor fan is lowered or the external air temperature reaches a temperature at which cooling operation or heating operation is to be performed.

(4) The dry operation mode can be selected only before the start of operation. That is, once the air conditioner operation has been entered into the cooling operation or the heating operation, the operation cannot be shifted to the dry operation while continuing the operation.

There is the following absurdity for the above items listed as prior arts.

(1) Although the blowing operation is effective for drying laundry indoors when the compressor is stopped, it cannot be said that the fan function is actively used during the drying operation.

(2) When the laundry is dried (dry) indoors, the laundry is generally placed in the downward direction of the front slope of the indoor fan. By the way, in the cooling operation, the compressor is operated, even if the laundry is blown by wind, the discharge temperature is low and the relative humidity is high, so there is little dehumidification effect. Therefore, the louver may be horizontally fixed during compressor operation. However, the compressor does not do so in view of lowering the humidity of the room by the cooling operation, although there is a significant drying effect just by hitting the room temperature wind. In addition, the louver for heating and drying operation is more effective in direct contact with the laundry regardless of whether the compressor is on or off. However, it is not always possible to expect an effective drying effect with the fixed fixed downward slope.

(3) In a monitoring state where it is not possible to determine whether it is a cooling operation or a heating operation, it is not effectively utilized even if the wind can be sufficiently dried by washing the laundry under the same temperature.

(4) The situation that one hopes to enter a dry operation for reasons such as going out after being put into an air-conditioning or heating operation is a matter of reality. Nevertheless, conventionally, once the air conditioner in operation is stopped, the user cannot enter the dry operation. The present invention has been made in consideration of the above circumstances, and an object of the present invention is to provide a drying operation method of an air conditioner that can perform laundry drying more efficiently using an air conditioner.

In order to achieve the above object, the present invention allows to control the air direction or the air volume of the indoor fan finely and to select a more detailed operation mode.

According to the present invention, the air direction or air volume of the indoor fan is finely controlled in a form suitable for drying conditions of the laundry, and a more detailed operation mode is selected. Drying operation is selected via the remote control. If the dry operation is selected in the air condition stop state, the contents of the dry operation are determined by the environmental conditions at that time. If the remote controller is operated to convert the air conditioner to a dry operation while the air conditioner is being operated for a purpose other than the dry operation, the contents of the dry operation are mainly determined by the previous operation mode. In addition, when the previous operation mode is "automatic operation and monitoring", the contents of the drying operation are determined according to the environmental conditions at that time. The cancellation of the drying operation is executed by setting change operation or stop operation to another operation mode (cooling, heating or automatic).

By selecting an appropriate operation mode among the operation of a plurality of operation modes including a strong wind blowing operation mode at the time of drying operation, and selecting a more reasonable blowing direction and air volume from the viewpoint of drying operation, it is possible to avoid the irrationality of the prior art and furthermore, to achieve efficient drying. It can be effective.

The outline of the drying operation method according to the present invention is as shown in Figs. Referring to the operation method at the time of air conditioner normal operation (not a dry operation), FIG. 12 shows the operation method regarding a dry operation in FIG. 13, and the operation method regarding automatic operation in FIG.

12 shows that the room temperature T _a and the set temperature T _s are T _a ≥ T _s (cooling operation) or T _a ≤ T _s (heating operation) for the normal cooling operation mode and the heating operation mode, respectively. If not (ie T _a <T _s (cooling operation) or T _a > T _s (heating operation)), the four-way valve for heating and cooling switching on (heating, off (cooling)), Compressor on / off, air volume of indoor fan (H = strong, M = medium, L = weak, UL = strong, automatic setting or manual setting), indoor louver direction, humidifier operation (with or without), on / off timer It is described with respect to the so-called basic control state of the air conditioner.

13 is classified into three modes of cooling operation, heating operation and blowing operation according to the present invention, and shows the operation states of the above-described devices. In this operation mode, control is performed in accordance with room temperature Ta, set room temperature, and set humidity.

FIG. 14 is divided into respective modes of cooling operation, heating operation and monitoring in the case of the normal automatic operation mode. In the cooling / heating operation mode, control is performed in accordance with the relationship between the room temperature Ta and the set room temperature Ts, and in the monitoring mode, all of them are basically stopped only by the blowing operation at the strong air volume.

The details of each operation state described above will be described in detail in the following Examples. In addition, in room temperature control and humidity control, in practice, it is common to have a hysteresis of 0.5 ° C and 5% humidity between the operating point and the return point to stabilize the control operation. In FIG. 14-and the powchart mentioned later, it abbreviate | omits and shows.

DETAILED DESCRIPTION OF THE INVENTION The present invention will be described in detail below with reference to the drawings. First, an apparatus configuration of an air conditioner used for practicing the present invention will be described.

2 is a system diagram showing the overall configuration of an air conditioner to which the present invention is applied. The refrigeration cycle of this air conditioner consists of a compressor (1), a four-way valve (2), an outdoor heat exchanger (3), an expansion valve (4) and an indoor heat exchanger (5). The air conditioner can be operated as a heater or a cooler by switching the four-way valve 2 on and off. In the case of the cooling operation (off the four-way valve 2), as shown by the solid line, the refrigerant is the compressor (1). In order to pass through the four-way valve (2), outdoor heat exchanger (3), expansion valve (4), indoor heat exchanger (5) and four-way valve (2) in order to return to the compressor (1). In the case of heating operation (four-way valve (2), on), as indicated by the broken line, the refrigerant is transferred from the compressor (1) to the four-way valve (2), the indoor heat exchanger (5), the expansion valve (4), and the outdoor heat exchanger. (3) and the four-way valve (2) in order to return to the compressor (1). The outdoor heat exchanger (3) is provided with an outdoor fan (6) for promoting heat exchange with the outside air, and the indoor heat exchanger (5) has an indoor fan (7) for blowing air heat-exchanged therein to the room; Louvers 8 are provided to adjust the direction of blowing. The compressor 1 is variable speed driven by the motor 9. The compressor (1), four-way valve (2), outdoor heat exchanger (3), expansion valve (4) and outdoor fan (6) constitute an outdoor unit, and also an indoor heat exchanger (5), indoor fan (7) and louver. 8 constitutes an indoor unit 20 (see FIG. 3).

The indoor temperature T _a is detected by the room temperature sensor 10, the indoor humidity H _a is detected by the humidity sensor 11, the outdoor temperature T _o is detected by the external temperature sensor 12, and each detection signal is calculated by a calculation control unit ( 14). The room temperature sensor 10 and the humidity sensor 11 are installed near the intake port of the indoor unit, and the external temperature sensor 12 is installed near the intake port of the indoor unit. The operation controller 14 is provided with various commands as described below through the receiver 13 in the wireless remote controller 30. The arithmetic and control unit 14 controls the on / off and rotational speed of the motor 9 so that the room temperature T _a is close to the preset room temperature T _s . The compressor 1 is controlled on / off or speed in cooperation with the motor 9. The operation control unit 14 is constituted by a microcomputer including a central processing unit (CPU), and the operation control operation is executed by software shown in a flowchart.

FIG. 1 shows a part controlled by the operation control unit 14 in a form partially overlapping with FIG. 2. The arithmetic and control unit 14 passes through the driver 15 according to the arithmetic processing result, and the compressor 1 (on / off, operating frequency), the four-way valve 2 (on / off, that is, heating and cooling), and an outdoor fan ( 6) (on / off), the indoor fan 7 (on / off, blowing amount) and the lever 8 (direction at the time of fixing, swinging and fixing) are controlled. The speed control of the compressor 1, that is, the speed control of the motor 9, is executed after the frequency converter, for example, the output frequency control of the inverter, which is not shown by the operation control unit 14. Similarly, the indoor fan 7 has a high (H), medium (M), weak (L), weak (UL) and stop (through the speed switching of the drive motor (not shown) by the operation control unit 14 ( It is supposed to be able to change the airflow in five stages of OFF).

3 shows the arrangement of the indoor unit 20 in the room. The indoor unit 20 heat-exchanges the indoor air attached to the upper part of the barrier 21 and drawn in the front direction as indicated by the arrow through the indoor heat exchanger 5, and also moves the louver 8 through the indoor fan 7. Blow into the room from the installed vent. The louver 8 direction (angle) will be described later.

4 shows a situation in which a humidifier interworking with the air conditioner is installed indoors. The indoor unit 20 is attached to the upper part of the barrier 21 and the humidifier 22 is installed on the floor (or pedestal). have. This humidifier 22 is mainly used to increase the room humidity, which is too low for a heating heater of the winter season, to an appropriate humidity. The humidifier 22 is provided with a receiver 23 and the transmitter 24 of the indoor unit 20 wirelessly transmits a control signal based on the indoor humidity to the receiver 23 of the humidifier 22 based on the indoor humidity. (22) can be controlled on and off.

The arrangement relationship between the indoor unit and the laundry when the laundry is hung and dried in accordance with the present invention will be described with reference to FIGS. 3 and 6.

5 shows a general laundry drying situation. At the same time as attaching the indoor unit 20 to the upper part of the interior wall 21, the portable laundry machine of the portable type (preferably assembled) in the front direction of the indoor unit 20 sets the appliance 25 and the laundry ( 26) will be hung. When the laundry is dried, the direction of the louver 8 may be in a swinging state other than being fixed in a horizontal direction H or an inclined downward direction K, and may be in a state of directly facing down, although not shown.

6 is installed so that the laundry roll bar 28 is positioned in the front of the louver 8 through the attachment man 27 in the indoor unit 20 and the laundry 26 is suspended on the laundry roll bar 28. One situation is shown.

FIG. 7 shows the planar appearance of the remote controller (remote controller) 30 used in connection with the method of the present invention with the cover covering the lower half. The remote control has a function of wirelessly transmitting various command signals to the indoor unit 20, as is known in the art. In the case of the remote control 30 shown in the drawing, an operation / stop key 31 is provided at the center thereof, Various function keys, for example, an operation switching key 32 for selecting an operation mode (such as cooling operation, heating operation or automatic operation, etc.), and a drying operation key 33 for selecting a drying operation mode for drying laundry. , The air volume change key 34 to switch the air volume of the indoor fan to H (strong), M (medium), L (weak), UL (weak), air volume automatic and off (stop), and change the blowing direction from the indoor unit Reservation / confirmation key (38), timer "on" key (39), timer "off" key (40), and timer "cancel" key ( A timer reservation unit 37 including 41 is provided. The reverse switching key 36 transmits a switching command signal each time compression operation is performed. Above the run / stop key 31, a display unit 45 for displaying the set temperature Ts and the like other than the set temperature change keys 42 and 43 and the humidity set key 44 for adding or decreasing the set temperature Ts is provided. . By pressing the humidity setting key 44, the humidity setting can be set to mode cycling among H, M, and L (e.g., 60%, 50%, 40%), and the setting value is displayed on the display section 45 for a short time (e.g., 3 seconds).

8 summarizes the functions of the operation keys of the remote controller 30 in a table form. When the operation / stop key 31 is operated, the operation command is output and the various setting contents (e.g., setting operation mode command, setting temperature, setting humidity, etc.) made up to it are output to the indoor unit ( To 20). If the operation / stop key 31 is stopped (on-operation during air conditioner operation), the air conditioner is stopped. The setting time TON and various setting contents by the on-timer operation by the timer &quot; on &quot; key 39 are output together with the on-timer command. The set time TOFF by the off-timer operation by the timer &quot; off &quot; key 40 is output together with the off-timer command. By the drying operation operation by the drying operation key 33, it is output with the operation time TOFF. When the cooling operation is selected by the operation switching key 32, each command of the set temperature Ts and the set air volume by the air volume switching key 34 is output together with the cooling operation command. When the heating operation is selected by the operation switching key 32, each command of the set temperature Ts, the set humidity Hs and the set air volume by the humidity setting key 44 is output together with the heating operation command. When automatic operation is selected by the operation switching key 32, the respective commands of the correction set temperature ΔT, the set humidity Hs and the set wind volume are output together with the automatic operation command. The correction setting temperature ΔT is set as follows. That is, during automatic operation, operation is basically performed at a fixed set temperature (for example, 23 ° C) selected by the air conditioner itself, but it is possible to change up and down by ± 2 ° C according to the user's preference. This is the correction set temperature [Delta] T and it is selectable by the user operating the set temperature change keys 42 and 43 in the automatic operation mode. Therefore, the display of the remote controller 30 shown in FIG. 7 is automatic operation, and the state of correction setting temperature (DELTA) T = + /-2 degreeC is set. In addition, the reverse wing command is output by the operation of the reverse wing key 36.

The swing operation of the louver 8 varies depending on the operating state of the louver wing key 36 and the equipment operating conditions at the start of operation. As shown in FIG. After that, the swing-on and the swing-off are repeated with each other when operating the reverse wing key (9). Also, within the range of normal operation (cooling or heating) to automatic operation, the louver state before the change is continued even if the operation mode is changed between them.

In the drying and cooling operation, the initial temperature deviation = T _a -T _s becomes more than a predetermined value based on the relationship between the detected temperature T _a and the set temperature T _s and the compressor 1 needs to be operated. (THERMO ON) ”is the first swing-off (locker fixed), and then the swing-on (rubber-wing) and the swing-off are repeated each time the louver wing key 36 is operated. The first swing when the initial temperature deviation = T _a -T _s is smaller than the predetermined value during the drying and cooling operation and the compressor 1 is to be stopped (this state is called the "thermo-off" state). (Rubber wing) and then, in this thermo-off state, the swing-off (locker fixation) and the swing-off are repeated with each other when the louver wing key 36 is operated. In dry cooling operation, the state of the louver wing at the time of thermo-on is remembered even if it is thermo-off and has nothing to do with the swing state at the time of thermo-off from the beginning. Similarly, in the drying and cooling operation, when the thermoswing state is in the thermo-off state, it is remembered even if the thermos are turned on later, and it is irrelevant to the swing state when the thermos are initially used.

Thermo-on (swing-on) → Thermo-off → Thermo-on (swing-on)

Thermo-on (swing-off) → Thermo-off → Thermo-on (swing-off)

Thermo-off (swing-on) → Thermo-on → Thermo-off (swing-on)

It is assumed that thermo-off (swing-off)-> thermo-on-> thermo-off (swing-off).

Next, the remote control processing performed in association with the operation of the remote controller 30 will be described with reference to FIGS. 15 to 17.

First, referring to FIG. 15, if the first air conditioner is in operation, a stop command is output by the on / off operation of the operation / stop key 31 (process 50, 51, 52), and various memory data during operation are erased. (Step 53) Prepare for a new operation command. If the operation / stop key 31 is not turned on during operation, it is checked whether the reservation / confirmation key 38 is turned on (step 54), and when it is operated, the process proceeds to step 61 (Fig. 16). If it is not operated, it is checked again whether or not the dry operation key 33 is on (operation 55). If it is operated, the process shifts to process 67 (FIG. 17), and if it is not operated, other necessary key processing is executed (process 56). Return to step 50.

Steps 61 to 66 (Fig. 16) are steps for confirming various key operations by the remote controller 30. Process 61 is a process of display by &quot; display mode 1 &quot;. In this display mode (1), as shown in FIG. 10, a "auto" mark for automatic operation, a timer mark indicating by the clock symbol that the operation time timer is set, and a drying operation are executed. The dry operation mark represented by the symbol and the rest of the operation time set by the timer in advance, i.e., the remaining operation time, are displayed. After this display, the display timer is once cleared and restarted (step 62). The display time is waited for a predetermined display time (for example, 3 seconds) (steps 63 and 64), and the display timer is cleared (step 65). Display mode 2 &quot; (step 66). In display mode 2, as shown in FIG. 11, an &quot; auto &quot; mark, a timer mark, and a drying operation mark are displayed. After this display, the process returns to step 50.

If the operation during the operation stop command to stop process execution of the air conditioner, and dismantling the indicated memory of "during operation" and (process 80,81,82), the plug S ₁ and S ₂ of the louver swing memory S ₁ respectively = 0, S ₂ = 0 (process 83), where plug S ₁ is a reverse wing control plug except when it is thermo-off in dry cooling.

S ₁ = 0 ... louver fixed

S ₁ = 0 ... reverse wing

Similarly, plug S ₂ is a louver swing control plug at the thermo-off with dry cooling.

S ₂ = 0 ... louver fixed

S ₂ = 0 ... reverse wing

Indicates.

If there is an operation command when not in operation (during stop), the fact that the air conditioner is "in operation" is stored along with the "setting contents" sent from the remote controller 30 (steps 80, 84, 85). Herein, the setting content indicates the operation / stop command sent from the remote control unit 30 and the contents of the various settings according to the setting. More specifically, the setting content indicates the operation mode (described later), the set temperature T _s , the set humidity H _s and the set air volume. Say data about. After the storage process of step 85, the on-timer TMI is reset (step 86), and the flag processes S ₁ = 0 and S ₂ = 0 of step 83 are executed. When there is no stop command during operation (steps 80 and 81), step 94 (Fig. 19) or less is executed. When there is no operation command during stop (steps 80 and 84), it checks whether there is a dry operation command (step 87), and if there is a dry operation command, step 120 (Fig. 21) or less is executed. If there is no dry operation command, check whether the On Timer (TMI) command is input (step 88). If there is an input, the on-timer (TMI) is reset per day and then started in advance (step 89) to store the setting time TON and setting contents (step 90), and the process of step 83 is executed. If there is no on-timer input in step 88, it is checked whether the on-timer is in operation (step 91). In this case, check whether the input timer (counter time) TMI and the setting time TON are related to TMI≥TON (step 92) .If TMI≥TON, remember that it is in operation (step 93). To fulfill. If TMI <TON, go back to step 80. After the flag processing in step 83, the process returns to step 80.

In step 80, 81, if there is no stop command during operation, the process of step 94 or below (Fig. 19) is executed. First, it is checked whether or not automatic operation is started (step 94). If the automatic operation is started, the process is performed below the step 140 (Fig. 22). If the automatic operation is not started, it is checked whether or not there is a command to change the setting contents (step 95). If there is a change, the new setting contents are memorized (step 96), and the following process is executed. If the setting is not changed, the timer (TMI) is reset and restarted (step 98), the setting time TON and the setting are memorized (step 99), and the process proceeds to step 82 (Fig. 18) and the operation is stopped. do. When there is no on-time command input in step 97, it is checked whether or not there is an off-time command input (step 100). If there is an input, the off-timer TM2 is reset and started (step 101), the off-timer setting time TOFF is stored (step 102), and the following steps 170 (FIG. 24) are executed. In step 100, if there is no input of the off-timer, a comparison is made whether the off-timer count time TM2 and the set time TOFF are in a relationship of TM2≥TOFF (step 103). If TM2≥TOFF, the process proceeds to step 82 (Fig. 18). If TM2 &lt; TOFF, process 104 (Fig. 20) or less is set.

In step 104, the presence of a swing command is confirmed. If there is no swing command, the process 150 (Fig. 23) or less is executed. If there is a swing command, check whether the compressor is stopped (thermo-off) in dry cooling (step 105). The check S ₂ = 1 if If an inactive and (process 106), execute S ₁ = ₁ if S ₂ = 0 processing of the (process 107), S ₂ = 0 is executing the processing of S ₂ = 1, and (Step 108), each of steps 170 (FIG. 24) or below is performed. In step 105, if the compressor is not stopped by dry cooling, if S ₁ = 1, S ₁ = 0 (step 110); if S ₁ = 0, S ₁ = 1 (step 111). Then perform steps 170 (fig. 24) and below, respectively.

FIG. 21 (Steps 120 to 126) shows the operation mode decision processing for the drying operation that is executed when there is a dry operation command (see FIG. 18, steps 80, 84, and 87) with no operation command being stopped. The process is shown. First, the humidifier off command is output (step 120) and the humidifier 22 is kept at a standstill regardless of the temperature level, and the room temperature T _a , the indoor humidity H _a and the external temperature T _o are read (step 121). Check that the external temperature T _o read here is not T _o ≥20 ° C (step 122). If T _o ≥20 ° C, check again that the room temperature Ta is T _a ≥24 ° C (step 123), where T _a ≥24 ° C sets the operation mode to `` dry cooling '' operation and sets and remembers 124), the flag S ₂ of the reverse wing is set to S ₂ = 1 and the flag S _{1 is set} to S ₁ = 0 (step 125). If T _o in step 122 is T _o <20 ° C., it is checked whether T _a ≧ 24 ° C. in relation to room temperature T _a (step 126). Where T _a according to ≥24 ℃ one time and the process 123 T _o the operating mode when the ℃ ≥20 to "dry conditioning" operation, and set the content and storing the (process 127), the flag S ₁ of the swing louver S ₁ = 1 (step 129). If T _a <24 ° C in step 126, the operation mode is "dry heating" operation, the contents are set and stored (step 128), and the process proceeds to step 129. After the operation mode for the dry operation is determined in steps 121 to 129, the off timer is set based on the set time TOFF data added to the dry operation command from the remote controller 30 in step 130 and below. First, the operation of the previous off-timer is reset in mode and the time data TOFF sent is stored and the operation of the new off-timer TM2 is started (step 130). Thereafter, the memory processing (step 131) of &quot; during operation &quot; is executed, and the process proceeds to step 170 (Fig. 24) for executing the actual operation process. In the case of an air conditioner without a heating function (drying only), there is no operation mode called 'dry heating', and thus, steps 126 and 128 are omitted. do.

FIG. 22 shows the automatic operation mode selection process executed in the case of YES in step 94 (FIG. 19). First, the external temperature T _o and the room temperature T _a are read (step 140). Make sure that the room temperature T _a read here is T _a > 23 ° C (Step 141). If T _a > 23 ° C, set the operation mode to "Auto Cooling" and store it as set room temperature T _s = 23 ° C + ΔT ( Step 142) Step 170 (FIG. 24) is performed. In step 141, when T _a ≤ 23 ° C, it is checked whether T _o ≤ 17 ° C with respect to the external temperature T _o (step 143). If T _o ≤ 17 ° C., set the operation mode to “automatic heating” operation, store the set room temperature T _s as T _s = 23 ° C. + ΔT (step 144), and execute step 170 (Fig. 24) or less.

By setting the T _o> operation mode is 17 ℃ in step 143 to the "automatic monitoring" performs the (process 145), process 160 described below. Here, the automatic monitoring means that the room temperature is close to the set room temperature, and neither the cooling operation nor the heating operation (stop the compressor 1) is made the indoor fan 7 be "UL" (strong and weak operation), and the change of room temperature T _a is made. Refers to the "predictive prediction" operation status being monitored.

FIG. 23 shows the processing process when it is determined in step 104 (FIG. 20) that there is no swing command. First, the presence or absence of a dry operation command is confirmed (step 150). This confirms whether or not a dry operation operation is performed during operation. If there is no dry operation command, the operation mode is checked (Step 151). If it is "Cooling" or "Auto cooling", it is the process 152. If it is "Heating" or "Auto heating", the process 155 is "Automatic monitoring" Proceed to step 157, respectively. In step 152, setting memory of operation mode = dry cooling is executed, and then S ₂ = 1 for plug S ₂ of the reverse wing memory (step 153) and S ₁ = 0 for plug S1 (step 154). Proceed to step 159. In step 155, the setting memory of operation mode = dry cooling is executed, and then the plug S ₁ of the reverse wing memory is set to S ₁ = 0 (step 156).

In step 157, the external temperature T _o is read and then checked whether T _o ≤ 17 ° C (step 158). If T _o ≤ 17 ° C., the process proceeds to step 155, and if T _o > 17 ° C., the process proceeds to step 152. After the operation mode in the dry operation is determined in steps 150 to 158, the process proceeds to step 159 or step 156, and the off-timer is set based on the set time Toff data added to the dry operation command from the remote controller 30. do. First, the operation of the previous off-timer TM2 is newly started (step 161). The process then proceeds to step 170 (FIG. 24), which is the actual operation process.

If according to process 150 there is no drying operation command automatically checks for operation and monitoring if and 162, when the YES external temperature T _o and reads the room temperature T _a (process 163) the read room temperature, where T _a is T _a > 23 ° C (step 164), and if T _a > 23 ° C, operating mode = automatic cooling, and set and store the set room temperature T _s = 23 ° C + ΔT (step 167), and step 170 (step 24). Do the following. In step 164, when T _a ≤ 23 ° C, check whether T _o ≤ 17 ° C with respect to the external temperature T _o (step 166) .When T _o ≤ 17 ° C, operation mode = automatic heating, and the actual room temperature T _a It sets and memorizes as Ta = 23 degreeC + (DELTA) T (step 167), and performs below process 170 (FIG. 24). Also run the T _o> or less when the 17 ℃ continue to monitor and not the automatic operation of the monitoring process 170, respectively (claim 24 degrees) in the process 162. In process 166.

In step 170 (FIG. 24), reading is performed at room temperature T _a and room humidity Ha. Next, the operation mode is determined (step 171), and in step 172 for automatic cooling or normal cooling, step 172 for normal heating and automatic heating. At step 175, the process goes to step 181 for dry heating, to step 184 for dry ventilation, to step 185 for automatic monitoring, and to step 186 (fig. 25) for dry heating. In addition, this processing can be referred to FIGS. 12 to 14 described above.

For an automatic air-conditioning, cooling usually in the process 172. As for the room temperature T _a T _a ≥Ts determine whether and when the T _s ≥T _a compressor (1), the four-way valve 2 is turned off (heating), the indoor fan (7) outputs each command of the horizontal louver (8) as set (step 173). When T _a <T _s , the compressor (1) is turned off, the four-way valve (2) is turned off (cooling), and the indoor fan (7). ) = L (about), outputs each command of the louver (8) horizontal (process 174), and executes process 193 (re-26 degrees) or less below.

In the case of normal heating and automatic heating, in step 175, it is confirmed whether or not the indoor humidity H _a is equal to or higher than the set humidity H _s of the remote controller 30, and if H _a ≥ H _s , a command of the humidifier off is output (step 176). If H _a ≤ H _{s, the} humidifier on command is output (step 177), and each of T _a ≤ T _s is checked (step 178). If T _a ≤ T _s, compressor (1) on, four-way valve (2) on (heating), indoor fan (7) = as set, and louver (8) = each set output below slope and just below. (Step 179), T _a > T _s plane compressor (1) off, four-way valve (2) on (heating), indoor fan (7) off, louver (8) = each set output directly below the slope (Step 180), and the following steps 193 (Fig. 26).

In the case of dry heating, in step 181, it is confirmed whether the room temperature T _a is 28 ° C. or lower, and if T _a ≤ 28 ° C., the compressor (1) temperature, the four-way valve (2) temperature (heating), and the indoor fan (7) = H (Strong), the louver (8) outputs each instruction below the inclination (step 182) and executes the following step 193 (Fig. 26). In step 181, when T _a > 28 ° C, the compressor 1 outputs, the 4-way valve 2 turns on (heating), the indoor fan (7) = H (strong), and outputs each command below the inclination of the louver (8). (Step 183), Step 193 (Fig. 26) and the following are executed.

In the case of dry blowing, in step 184, the compressor (1) is turned off, the four-way valve (2) is turned off (heating), the indoor fan (7) is H, and the louver (8) is output. 193 (Fig. 26) or less is executed.

In the case of automatic monitoring, in step 185, each command output of the compressor (1) off, the four-way valve (2) off (cooling), the indoor fan (7) = UL (strong) and the louver (8) is executed. (Figure 26)

In the case of dry cooling, as shown in FIG. 25, it is checked whether the room temperature T _s is 22 ° C. or higher (step 186), and if T _a ≥ 22 ° C., it is continuously checked whether the room humidity Ha is 80% or less. (Step 187). If H _a ≥80%, each command of the compressor (1) on, the four-way valve (2) off (cooling), the indoor fan (7) = M (medium), and the louver (8) is output (process 188). Go to Step 193 (Figure 26). When T _a <22 ° C in step 186 or H _a <80% in step 187, the compressor 1 is turned off, the four-way valve 2 is turned off (cooling), and the indoor fan 7 is H ( Strong), the command below the tilt of the louver 8 is output (step 189), and the verification of the graph S ₂ is executed (step 190). If S ₂ = 1, the command of the reverse wing-on is output (step 192), and if S ₂ = 0, the command of the reverse wing-off is output (step 192), and the series of processes are completed (26 degrees).

In step 193 (re-26) executed after the processing in FIG. 24, a check is made as to whether S ₁ = 0 or not with respect to the plug S ₁ . If S ₁ = 0, the command of the swing fan (stop) is output (step 194). If S ₁ = 0 (that is, if S ₁ = 1), the command of the swing fan (7) is output. (Step 195) and end the series of steps.

Process 190-195 (Fig. 25 and Fig. 26) are part of the louver swing motion and the process 193-195 is louver swing plug to decision process louver seuwingga portion in the operating state other than the compressor is stopped when the dry air-conditioning ₍₁ S In this case, if the louver wing operation is not performed in Ribocon, the previous procedure is performed during normal or automatic heating, normal or automatic cooling, automatic monitoring, and operation of the compressor for dry cooling. the louvers swing process because the plug because it is set to 0 (S ₁₎ when the louver is fixed and during the drying heater and the drying air flow without swinging is 1 is set to the swing louver plug (S ₁₎ in the course of its previous 182~ The louver swings about the downward louver slope set at 184 (Fig. 24). One process 190 to 192 is a process of determining the louver wing addition or not in the operation state during the operation of the compressor for dry cooling, and the louver wing addition is determined by the louver wing plug S ₂ . In this case, if the louver wing operation on the remote control is not performed, the louver swings around the louver slope set in step 189 (Fig. 25) because 1 is set in the reverse wing plug (S ₂ ). do.

In addition, the louver direction in each operation will be explained with reference to FIG. 3 in the a direction is the louver direction during normal monitoring during automatic or automatic cooling and during compressor operation for dry cooling, and is set substantially horizontal to the ceiling surface. On the other hand, the b direction is the louver direction of normal or automatic heating and is set to? 1 = 40 to 60 °, preferably 50 ° in the a direction, i.e., downward to the ceiling surface. In addition, in the case of dry heating, the drying blower and the stop of the compressor during dry heating are set in the c direction, that is, in the downward direction with respect to the ceiling surface, θ2 = 30-40 °, preferably 35 °.

The difference between the b direction and the c direction is that the normal or automatic heating improves the user's temperature environment in the room, and the user usually has a lower warmth because the user is closer to the ceiling surface than the laundry to be dried. It is intended to reach.

FIG. 27 shows the change in the drying rate when the laundry is dried by the drying method according to the present invention described above in the air blowing mode (solid line) and in the heating operation mode (dashed line). The operating conditions for obtaining this data are

(1) Air volume H (strong)

(2) The louver 8 is fixed toward the direction of theta 26

In both operation modes, the room temperature T _a and the room humidity H _a at the start of operation were the same.

It can be seen from the twenty-seventh that, for example, in the case of the blowing operation, it is possible to improve the drying effect than in the cooling operation by adjusting the direction of the louver 8 and making the wind contact the laundry 26 well by adjusting the direction of the louver 8. . In addition, the drying rate (%) is to be defined as follows.

Next, a little explanation is given about the modification of this invention.
