BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and in particular, to increase the speed of air discharged from an air conditioner, an air conditioner provided with a wind direction device capable of concentrating air in a predetermined area in a width direction or a horizontal direction of an air outlet. It is about the flag.

A conventional air conditioner has a wind direction device capable of selectively switching the flow of air in the vertical direction and the horizontal direction as described, for example, in Japanese Patent Laid-Open No. 62-276359. Japanese Utility Model Publication No. 62-2944 proposes an air conditioner having a wind direction device comprising a main wind direction plate disposed below the outlet of the air conditioner and an auxiliary wind direction plate disposed on the main air direction plate. These wind direction plates can change air in the vertical direction, and are provided over the horizontal length of the air outlet so that air can be distributed in the full width, ie, the horizontal direction.

Japanese Patent Laid-Open No. 60-16905 describes a technique in which a wind vane for deflecting air in a vertical direction is driven by a rotational position control device having a member made of a shape memory alloy. These wind vanes extend over the entire width of the air outlet.

Two air outlets for discharging the air in accordance with Japanese Patent Laid-Open No. 57-73331 to the outside of the living space when the heat source is turned ON, and discharging the harmonized air into the living space when the heat source is turned OFF. An air conditioner having a is disclosed. In this technique, the wind direction plates of the two air outlets have the same inclination angle.

Japanese Patent Publication No. 58-4256 consists of a pair of outlets for driver and assistant, and has a central air outlet that can be manually adjusted to deflect the harmonized air in the vertical and horizontal directions. Air conditioners are suggested. However, this publication does not suggest any technique for concentrating air to the central area of both air outlets by shielding the outer area of the outlet.

In the above-described prior art, an air conditioner or wind direction plate is provided over the entire width of the air outlet. These throttles and wind vanes are rotated or inclined to deflect the harmonized air in the vertical direction or to direct the air in one direction, but the air outlets are formed so that a constant flow of discharged air is formed along the outlet of the air conditioner. The air is uniformly distributed over the entire width.

Thus, in these prior arts, the flow of air to the center, left or right side of the air outlet allows the harmonized air to reach the harmonized air to a desired area particularly required by the user, e. The idea of partially shielding the flow of backed air is not proposed in order to concentrate this.

In recent years, inverter-driven air conditioners have become popular. This type of air conditioner is capable of generating large heating outputs to meet the heating demands in winter. In general, the inverter driving air conditioner is economical because it is designed to change the operation to a low output mode so that the frequency of power ON and OFF is minimized when the indoor temperature is set to a stable state. Under these stable conditions, very low air temperatures tend to be lower in the area near the bottom, even if the temperature difference is small compared to the air in the level area around the head of the occupant.

In general, from the physical and physiological point of view, the air temperature around the feet and legs is preferably slightly higher than the air temperature around the head.

Under such circumstances, there is an increasing demand for an air conditioner that locally reaches a harmonious air, for example, an area where warm air is desired, that is, an area of an indoor floor.

An object of the present invention is to solve the problems of the prior art, to provide an air conditioner capable of concentrating harmonized air to the desired area of the room.

In order to achieve this object, according to the present invention, there is provided an air conditioner having an outlet for rough air and a wind direction means coupled to the outlet. The wind direction means comprises at least a first wind direction device capable of rotating around the horizontal side to change the air conditioned through the outlet port, shielding the width portion of the outlet port, and forming a ventilation path for the conditioned air to be discharged. And a second rotatable wind vane that opens one other width portion.

According to the present invention, it is possible to concentrate the air that has been harmonized into the desired area of the room. Therefore, in the heating operation, it is possible to reach the warm air to the area near the floor in the room in order to achieve rapid heating. Likewise, during cooling, the desired area of the room can be cooled rapidly. In addition, the present invention can create a mild indoor air condition as desired. The air conditioner of the present invention is simple in construction and inexpensive. This simple configuration has the advantage that it causes less trouble and facilitates maintenance and inspection.

The above and other objects and novel features of the present invention will become apparent from the description and the accompanying drawings.

Best Mode for Carrying Out the Invention Embodiments of the present invention will be described below with reference to the drawings.

1 to 14 show a first embodiment.

Referring to FIGS. 1 and 2, the main part of the air conditioner, that is, the indoor unit, has an outlet 2 for discharging air harmonized with the air inlet 1a for sucking indoor air to the air conditioner from the air conditioner to the room. It has a front cover (1) having. In addition, the unit functions as a horizontal vane 3 which serves as the first wind direction device for changing the air discharged from the discharge port 2 in the vertical direction, and a vertical which functions as a second wind direction device for changing the air to the right and left. It has a wing (4).

In addition, the indoor unit has a movable blade 5 which functions as a third wind direction device irrespective of the horizontal vertical wings 3 and 4. This movable blade 5 is partially open to shield the rest of the outlet 2 and to form the ventilation path 2a.

The indoor unit also has a heat exchanger 6 and a drain pan 7. The drain pan 7 forms an air discharge passage with the housing 8. The blower 9 sucks air into the indoor unit through the inlet 1a and the heat exchanger 6 as indicated by arrow A. FIG. The air conditioned by the heat exchanger 6 is discharged by the blower 9 into the room as indicated by arrow B. FIG.

The horizontal wing drive motor 10 which is a step motor and functions as a first wind direction motor is directly connected to the axis of the horizontal wing 3.

The movable blade drive motor 10 ', which is a step motor and functions as a third wind direction motor, is directly connected to the shaft of the movable blade 5.

The movable blade 5 operates separately from the operation of the horizontal blade 3 and the vertical blade 4, and provides a ventilation path 2a for concentrating the air flow in the direction of the arrow to the center region of the discharge port 2. The outlet of the outlet 2 can be partially shielded to form.

When air is discharged over the entire width of the discharge port 2, the movable blade 5 is rotated in the direction of arrow X as shown in FIGS. 3 and 4, and discharged as shown by arrows C and D. FIG. Stop at a position that does not interfere with the flow of air. The horizontal blade 3 and the vertical blade 4 can be operated independently even in this operating state.

5 shows a variant using the movable blade 11 having an opening in its left half so that air is discharged from the left half of the outlet 2 when the movable blade 11 is in the operating position.

6 shows another variant using the movable blade 12 having an opening in its right half so that air is discharged from the right half of the outlet 2 when the movable blade 12 is in the operating position. It is.

FIG. 7 shows another modification in which the position of the ventilation path 2a is set at any desired position according to the width of the outlet 2.

In particular, the shielding plate as indicated by arrows Y and Z along the guide frame 13 extending over the entire width of the outlet so that the ventilation path 2a is formed only at the left and right ends of the outlet 2 or at the left or right side of the outlet 2. 14 is provided to move in the width direction of the discharge port.

The shielding plate 14 may be constituted by a plurality of segments so that the ventilation path 2a can be set at any desired position along the width direction of the outlet 2.

Advantages of this embodiment will be described with reference to FIGS. 8 to 11 as compared with the prior art.

8 shows the temperature distribution of indoor air when heated by the warm air discharged from a conventional air conditioner operating in the heating mode and discharging air at a low speed. As can be seen in FIG. 8, air does not reach a position below the level of 0.5 to 0.55 m on the floor at 30 ° C.

On the other hand, as shown in FIG. 9, in the raised state of the air conditioner of this embodiment, air at 30 ° C reaches the bottom surface, and even air at 35 ° C can reach a level of 0.1 to 0.15m on the floor. Can be. Therefore, the area of the bottom surface is directly heated by the air discharged from the air conditioner.

FIG. 10 shows a rise pattern of indoor air temperature at a level of 5 cm on the bottom surface achieved by the conventional air conditioner and the air conditioner of the embodiment of the present invention when the ambient air temperature is 5 ° C. . As can be seen in FIG. 10, a conventional air conditioner requires approximately 6 minutes to heat indoor air to 21 ° C., but the air conditioner of the present invention requires approximately 3 minutes to heat indoor air to 21 ° C. FIG.

As can be seen here, the room air is heated at a desired temperature, for example 21 ° C. at once, and the user can switch the air conditioner to a mode that gently discharges the warm air at a gentle rate in the entire part of the exhaust port 2. It can be seen that there is.

It is also clear that the air conditioner of the embodiment can be quickly raised in the cooling mode. Then, the desired area can be cooled to the desired temperature at a time, and the horizontal blade 3 is rotated to a substantially horizontal position so that the cold air is smoothly discharged.

Next, the opening hole ratio of the ventilation path will be described. In this specification, the opening porosity means the ratio 1 / L of the length 1 (see Fig. 1) of the portion of the movable blade 5 defining the ventilation path 2a to the full width L of the outlet 2. . In the configuration shown in FIG. 7, the length L is given by L ₁ + L ₂ , where L ₁ and L ₂ are areas not shielded by the left and right ventilation passages 2a and 2a, that is, the shielding plate 14. Indicates the length of the region defining

11 shows how the average temperature (° C.) and the noise level (dB) measured at a level of 5 cm on the floor surface change with respect to the change in the opening hole in L / L. As can be seen from FIG. 11, it can be seen that the average temperature at the level of 5 cm on the bottom surface becomes large when the opening porosity l / L decreases. However, the reduction of the opening hole rate involves a series of increase in the noise level. In order to suppress the noise so that the noise level is 43 dB below the average air temperature of 21 ° C. in the area of 5 cm on the floor, the opening porosity should be set within the range of 0.4 to 0.8 as shown in FIG. However, for stability, it is preferable to determine the opening porosity in the range of 0.65 to 0.75 in this embodiment. These effects obtained by the above-described embodiments can also be obtained in all of the embodiments of the present invention described below.

The horizontal blade 3 and the movable blade 5 are preferably rotated by a motor such as a manual or step motor. An embodiment in which the horizontal blade 3 and the movable blade 5 are driven by the respective motors 10 and 10 'under microcomputer control will be described.

The air conditioner shown in FIG. 1 is provided with a remote control device 40. As shown in FIG. 12, the remote control device 40 changes the wind direction control buttons 41 and 41 'for controlling the horizontal wing drive motor 10 and the movable wing drive motor 10', and the set temperature. A temperature control button 42 and a microcomputer 43 for receiving and processing signals from these buttons and outputting a control signal to the transmission circuit 44.

The air conditioner itself has a microcomputer 54, a reception circuit 55 for receiving a signal transmitted from the transmission circuit 44 of the remote control device 40, a room temperature sensor 56 and the like.

The microcomputer 54 has a control unit 59 and a storage unit 60 for storing data such as the number of pulses and the set temperature supplied to the wing drive motors 10 and 10 '. The control unit 59 receives data from the receiving circuit 55, the room temperature sensor 56 and the storage unit 60, and the indoor fan motor 58, the compressor 57, the horizontal wing drive motor 10 and the movable wing drive motor. Various calculations are performed to output a control signal to an external device such as (10 ').

The remote control operation executed through the remote control device 40 will be described with reference to FIGS. 12 and 13.

As shown in FIG. 13, the microcomputer 43 of the remote control device 40 monitors any one input such as the wind direction control buttons 41, 41 'and the temperature control button 42 (step). S-31). When the input is received, the microcomputer 43 determines from which button the input is output (step S-32). If the input is that of the temperature control button 42, the microcomputer 43 outputs the temperature control signal (step S-33). On the other hand, if the button is the wind direction control button 41 or 41 ', the microcomputer 43 outputs the wing control signal (step S-34). In response to these signals, the horizontal blade 3 is rotated in the direction of the arrow V (see FIG. 2) to point downward. The program is determined so that the movable blade 5 also rotates in the direction of the arrow V in accordance with the rotated horizontal blade 3.

The operation of the air conditioner itself will be described with reference to FIGS. 12 and 14.

When the ON state of the power supply 30 is confirmed (step S-51), the initialization of the control part 59, the clearing of the memory | storage part 60 which memorize | stores data, such as the number of pulses supplied to a wing drive motor, and a set temperature, The initialization operation of the executed microcomputer 54 is executed (step S-52).

Next, the horizontal blade 3 and the movable blade 5 are moved to the initial position, for example, the position shown in FIG. 4 by the initialization operation of the horizontal blade driving motor 10 and the movable blade driving motor 10 '. Initialization is executed as much as possible (step S-53), and the receiving circuit 55 is then initialized in step S-54.

After the initialization operation, the process proceeds to step S-55, which is waiting for any signal to be received by the receiving circuit 55. When the signal is received at step S-55, the type of signal is determined (step S-56). If the signal is a blade selection signal, an operation is performed to check the position of the movable blade 5 (step S-57). When the movable blade 5 is rotated in the direction of the arrow W in FIG. 2, the number of pulses to be supplied to the horizontal blade driving motor is stored in the storage unit 60 (step S-57). Next, the horizontal blade 3 rotates in the arrow V direction to the position shown in FIG. 2 (step S-59). Next, the movable blade 5 is rotated to a position which is opposite to the downstream end of the horizontal blade 3 (step S-60). In this state, the horizontal blade 3 and the movable blade 5 are inclined at 30 to 35 degrees from the vertical plane.

Next, the speed at which the indoor fan motor and the compressor are operated is calculated according to the difference between the room temperature and the set temperature (step S-61), and a command corresponding to the calculated operating speed is issued to the indoor fan motor 58 and the compressor ( 57) (step S-62).

Calculation of the operating speeds of the indoor fan motor 58 and the compressor 57 may be performed using the control table shown below.

[Control Tables for Indoor Fan Motors and Compressors]

Since the air conditioner is not in an elevated state when the vane selection signal is received and the movable blade 5 is rotated in the direction of the arrow V to the position shown in FIG. 2, the indoor fan motor 58 and the compressor 57 are normally The command signal is given in step S-63 to reset to the operating state of. Next, the movable blade 5 is rotated in the direction of arrow X to the position shown in FIG. 4 (step S-64), and the pulse to be supplied to the horizontal blade drive motor stored in the storage unit 60 prior to the selection of the blade. The number is read (step S-65). Next, a command signal is given to the horizontal wing drive motor 10 in step S-56.

However, when the kind of signal in step S-56 is a temperature signal, the process proceeds to step S-67 in which the temperature set in the storage unit 60 changes, and then the normal operation of the air conditioner is executed (step S). -68).

As can be seen from the above, the remote control device 40 can remotely control the position of the horizontal blade 3 and the movable blade 5 simply by pressing the wind direction control button 41 or 41 '. Can facilitate the operation of the air conditioner.

Particularly, when the wind direction control button 41 'is pressed, the movable blade 5 turns the end of the outlet 2 so that most of the discharged air is concentrated in the central ventilation path 2a, and the wind direction button ( When 41) is pressed, the movable blade 5 rotates to open the entire part of the outlet 2 so that air is discharged through the entire part of the outlet 2.

Therefore, in the above-described embodiment, the movable blade 5 is moved to a position where the left and right ends of the outlet 2 are closed so as to concentrate the harmonized air flow to the center portion of the width of the outlet 2. Thus, if the discharge rate does not change, the air velocity increases substantially in inverse proportion to the reduction of the discharge area of the discharge port.

Moreover, it is also possible to shield the left and right parts of the discharge port 2 using the movable blades 11 and 12, respectively.

If a shield plate 14 composed of a plurality of segments and slidable along the guide frame 13 is used, it is possible to direct the flow of air to any desired width or position of the outlet 2.

Another embodiment of the air conditioner of the present invention will be described with reference to FIGS. In all of the drawings for describing another embodiment, those having the same functions as those used in the above embodiments are denoted by the same reference numerals, and repetitive description thereof will be omitted.

As shown in Figs. 15, 16, 18 and 19, the air conditioner is integral with the main blade 23 and the main blade 23 which can change the air discharged from the discharge port 2; And a pair of second auxiliary wings 24 detachably disposed at both ends of the first auxiliary wing 23a and the first auxiliary wing 23a. In particular, the second auxiliary wing 24 is substantially in parallel with the first auxiliary wing 23a when the first auxiliary wing 23a integral with the main wing 23 is in the position shown in FIG. It is disposed at the same plane, but forms an angle with respect to the plane of the main blade 23 and the first auxiliary blade 23a when the main blade 23 and the first auxiliary blade 23a are rotated in a predetermined direction. Set to

In the figure, reference numeral 25 denotes a protrusion which functions as a stopper for restricting the rotation of each second auxiliary blade 24, and 26 denotes a rotation axis of the main blade 23.

The operations of the main wings 23, auxiliary wings 23a, and 24 will be described with reference to FIGS. 17A to 17D.

As shown in FIG. 17A, when the main blade 23 rotates in the direction of the arrow X, the first auxiliary blade 23a rotates together with the main blade 23 at the same angular position as the main blade 23. As shown in FIG. However, since the 2nd auxiliary blade 24 is stopped by the processus | protrusion 25, it remains in the above-mentioned position. In this state, the second auxiliary wing 24 shields the engaging portion of the air outlet. When the main blade 23 rotates in the direction of the arrow Y, the outlet 2 is shielded over its entire width as shown in FIG. 17B.

The normal operation of the air supply mode, the cooling mode or the heating mode can be executed by the rotating blades as shown in Figs. 17C and d. It can be seen that the fully shielded state shown in FIG. 17B and the partially shielded state shown in FIG. 17A can be obtained by reversing the main blade 23. The second auxiliary wing 24 is set in a plane different from the plane of the first auxiliary wing 23a as shown in FIGS. 16 and 17 only when the main wing 23 rotates in the arrow X direction. do. When the main blade 23 and the first auxiliary wing 23a are rotated in the direction of the arrow Y from the position shown in FIG. 17a to the position shown in FIG. 17b, the first auxiliary wing 23a is formed in a second manner. The common auxiliary shaft provided by the shaft 26 while maintaining the same plane as the main wing 23 and the first auxiliary wing (23a) to the same plane as the auxiliary wing (24). Rotate around. This operation of the second auxiliary wing 24 is performed by the mechanism described next with reference to FIGS. 18 and 19. FIG.

In this figure, the spring 27 is provided between the adjoining ends of each of the second auxiliary wings 24 and the main wings 23. This spring 27 is the first auxiliary when the main blade rotates in a direction opposite to the above-mentioned predetermined direction below the position shown in FIG. 17B, that is, when no force is applied to the second auxiliary wing 24. It functions as an elastic biasing means for biasing the second auxiliary wing which is coupled to be flush with the vane 23a.

Another embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 20, the air conditioner has a main wing 28 capable of changing the air discharged in the vertical direction, a first auxiliary wing 28a integral with the main wing 28, and a first auxiliary. Second auxiliary wings 29 are detachably provided on both sides of the wing 28a. Moreover, in the Example shown in FIG. 20, it has the movable blade 28b provided in one end of the main blade 28 so that it may extend in the width direction of the discharge port 2. As shown in FIG. The movable blade 28b rotates on the main blade 28 so as to form an angle with respect to the main blade 28 only when the main blade 28 rotates in the arrow Z direction. When the main blade 28 is rotated in the opposite direction, the movable blade 28b becomes flush with the main blade 28 again.

In this embodiment, the second auxiliary wing 29 shields the ends of both width directions of the discharge port 2 only when the main wing 28 is rotated in the direction of the arrow Z, so that the discharged air is concentrated and discharged to the center area. The speed of the air that is blown is increased when the discharge rate does not change. The second auxiliary wings 29 are spring biased so that they can be reset in the same plane state as the first auxiliary wings 28a when no external force is applied to these second auxiliary wings 29. In addition, the main blade 28 is rotated in the direction of the arrow Z to concentrate the air in the width center area of the outlet port 2, and the movable blade 28b on the main blade 28 is removed to remove any gap therebetween. As shown in FIG. 20, the contact with the drain pan 7 can increase the effect of concentrating air in the width center region.

Another embodiment of the present invention will be described with reference to FIGS. 21 to 25.

The air conditioner of this embodiment extends over the entire width of the discharge port 2, as shown in Figs. 21 and 22, and has a horizontal blade 33 capable of changing the air discharged in the vertical direction. In addition, the air conditioner has vertical wings 35, 35, and 36 that can change the flow of air discharged in the horizontal direction. These vanes 33 to 36 constitute the wind direction switching means.

As shown in FIG. 23, the vertical vane 34 is operatively connected to the motor 200 'by a link 201', in a direction perpendicular to the plane of the outlet 2 to form a ventilation path for exhaust air. Extending, the vertical vanes 35 and 36 are operatively connected to the other motor 200 by a link 201 and are set to shield the left and right ends of the outlet 2. The vertical wing group 35 and the vertical wing group 36 are driven independently of each other. The setting of the vertical blades 35 and 36 in the state shown in FIG. 23 is generally set at an incline toward their lower end toward the central vertical blade 34.

24 shows a modification in which the vertical blades 34 of the width center region of the discharge port 2 are set to form a ventilation path, and the left and right ends of the discharge port 2 are vertical wing 37a and vertical wing 37b. Are shielded in groups. In this variant, the vertical blades 37a and 37b are operably connected to the link 201 and operated by the common motor 200.

25 shows the motor 200 and independently of each other such that the two groups of the vertical wing 38 and the vertical wing 39 form an optional ventilation path 2a in the left half or right half of the outlet 2. Another variant is illustrated which is operated by 200 'and links 201 and 201'.

Therefore, in this embodiment, a plurality of vertical wing groups are selectively operable to partially shield the outlet 2, thereby forming the ventilation path 2a in the selected width region of the outlet 2. The air shielded by the vertical wing is exerted to flow through the ventilation path 2a, so that the air is concentrated in the ventilation path 2a. Therefore, as in the case of the above-described embodiment, the speed of the exhaust air is increased as the cross-sectional area of the ventilation path 2a decreases. In the configuration shown in Figs. 23 to 25, economical configurations can be realized because the vertical blades of the same group are operatively connected to each other so as to be operated at the same time.

Although not described, it will be apparent from the above description that the remote control device described in connection with the air conditioning control system and the first embodiment can also be used in the embodiment described with reference to FIGS. 15 to 25.

Another embodiment of the present invention will be described with reference to FIGS. 26-33D.

As shown in FIG. 26, a substantially rectangular outlet 2 is formed in the lower part of the front cover of the air conditioner. The outlet 2 has a horizontal length or width L _D and a vertical butterfly or height W _D. As can be seen in FIG. 26, the main wind direction plate 102 and the auxiliary wind direction plate 103 are disposed so as to close the center region of the discharge port 2 and the end region in both width directions, respectively. The wind direction device is formed by the main and auxiliary wind direction plates 102 and 103. The main and auxiliary wind direction plates 102 and 103 are rotatable independently of each other. In particular, the main wind direction plate 102 can be rotated in the clockwise direction as shown in FIG. 26 to partially open the outlet 2 while leaving the auxiliary wind direction plate 103 in the shielding position. In this state, the discharge port 2 is opened by the horizontal length or the width l of the main wind direction plate 102 smaller than the width L of the auxiliary wind direction plate 103, thereby limiting the ventilation path. On the other hand, when the auxiliary wind direction plate 103 and the main wind direction plate 102 rotate counterclockwise as shown in FIG. 26, the outlet 2 is discharged so that air is discharged through the full width portion of the outlet 2. Fully open, a large cross sectional area of the flow passage is obtained.

The operation of the above-described wind direction device will be described in more detail with reference to FIGS. 31 to 33D.

As shown in FIG. 31, which is a schematic perspective view of the wind direction device, the main wind direction plate 102 includes front and rear panels 120, 121, and both side panels 122, 123, side walls 122a, and 123a. It has the substantially rectangular cylindrical part 120a formed from the two cylindrical wing parts which have, and is arrange | positioned at the end part of the cylindrical part 120a. As shown by arrow A, the air passes through the central cylindrical portion 120a and both cylindrical wings. The trunnion shafts 124 and 125 are provided on both panels 122a and 123a. One or two of these trunnion shafts are suitably driven to rotate the main wind deflection plate 102 around the shaft center of the trunnion shafts 124 and 125.

The auxiliary wind direction plate 103 has a cutting part 100 that can receive the cylindrical part 120a of the center of the main wind direction plate 102, and has a shape that can be fitted to the upper and both ends of the central cylindrical part 120a.

Calculation of the operating speeds of the indoor fan motor 58 and the compressor 57 may be performed using a control table in the same manner as described above in connection with the first embodiment.

Receiving the wind direction plate separating signal while the auxiliary wind direction plate 103 has already been separated from the main wind direction plate 102 means that the air conditioner is not in an elevated state, so that the indoor fan motor 58 and the compressor 57 are normally The command signal is given in step S-163 to reset to the operating state of. Next, the wind direction apparatus is rotated to the initial position shown in FIG. 30 (step S-164), and the number of pulses to be supplied to the motor 10a stored in the storage section 60 is read prior to the separation of the wind direction plates (step S-164). S-165).

Next, a command signal is given to the motor 10a in step S-166.

However, when the kind of signal in step S-156 is a temperature signal, the process proceeds to step S-167 in which the temperature set in the storage unit 60 changes, and then the normal operation of the air conditioner is performed in step S-168. Is run on
