Holes 1A are formed on the left and right sides of the air conditioner 2 so that either one can be selectively used. The air conditioner 1 is configured with a heat exchanger 5 and an air blower 6 on the air passage where the air sucked in from the air inlet 3 flows to the air outlet 4A. The air inflow surface becomes the lower side, and the air blower 6 sends the air sucked in from the air inlet 3 to the air inflow surface of the heat exchanger 5. The air blower 6 adopts the mode of accommodating a fan 10 in the fan casing 9. The fan casing 9 has an inlet 7 for sucking in air from the air inlet 3 and an outlet 8 for sending air to the heat exchanger 5 . In the air conditioner body 2, the water receiving pan 25 is arranged directly below the lower end of the heat exchanger 5, so that the lower end of the heat exchanger 5 faces the upper opening of the water receiving pan 25, and receives heat from the water receiving pan 25. Dew from exchanger 5.

Next, the air conditioner 1 will be specifically described. The air conditioner 1 and the air conditioner body 2 having the front opening 2A are formed in a vertically long shape, and the front opening 2A of the air conditioner body 2 is covered by the front panel 11 attached to the air conditioner body 2 . In the front panel 11, an air inlet 3 and an air outlet 4A are formed. The front panel 11 consists of a lower front panel 11A with an air inlet 3 lengthwise formed on the left and right side faces obliquely forward, and left and right sides arranged obliquely forward. It consists of an upper front panel 11B in which air outlets 4A are formed on the side surface and the upper side surface provided obliquely forward. The lower front panel 11A is a molded body of synthetic resin integrally molded with a front wall 11A1 and left and right side walls 11A2 extending rearward and obliquely forward at the left and right ends. In addition, the upper front panel 11B is a molded body of synthetic resin that integrally molds the upper wall, the front wall 11B1, and the left and right side walls 11B2 that extend rearward at the left and right ends and are provided obliquely forward.

A vane mechanism is provided on the lower front panel 11A, and each air inlet 3 is opened and closed by an air inlet vane 16 driven by a motor 15 . The structure of air inlet vane 16 is to be formed into the plate shape of the elongated shape of the size of blocking air inlet 3, and the two ends of air inlet vane 16 are rotatably supported by the longitudinal axis portion 23 of air inlet 3, and the one end The shaft portion 23 is driven by the motor 15 . As shown in FIGS. 2 and 3 , the shaft portion 23 is located at the front of the air inlet 3 , and the air inlet blades 16 are opened left and right at the front of the air inlet 3 . Therefore, the structure is such that the air sucked in from the left and right air inlets 3 is sucked in from the lateral direction and the rear by the air inlet blades 16, and the air sucked in from the front is restricted. Therefore, when the power of the air conditioner 1 is turned on, the air inlet blades 16 are opened by operating the operation start switch of the air conditioner 1 provided with an operation unit such as a remote controller 60 operated by a person using the air conditioner 1 . Then, the air inlet blades 16 are closed according to the operation of the stop switch of the air conditioner 1 provided on the operation portion. In addition, a filter 3F for capturing dust in the air is detachably attached behind the air inlet blade 16 and on the back side of the air inlet 3 .

In addition, a blade mechanism for opening and closing each air outlet 4 is provided on the upper front panel 11B by an air outlet blade 19 driven by a motor. The structure of air outlet vane 19 is to be formed into the plate shape of the elongated shape of the size of blocking air outlet 4, and the two ends of air outlet vane 19 are rotatably supported by the length direction shaft portion 24 of air outlet 4, and the one end The shaft portion 24 is driven by the electric motor 18 . In the left and right air outlets 4 , as shown in FIGS. 2 and 3 , the shaft portion 24 is located behind the air outlet 4 , and the air outlet blades 19 are opened obliquely forward and left and right at the rear of the air outlet 4 . Therefore, the air blown out from the left and right air outlets 4 is restricted from being blown out backward by the air outlet blades 19 and blown forward.

In addition, in the upper air outlet 4 , the structure on the side of the shaft portion 24 at one end is driven by the motor 18 via the link mechanism 24A. As shown in FIG. 2 and FIG. 3 , the shaft portion 24 is located behind the air outlet 4 , and the air outlet vanes 19 are opened obliquely forward and upwardly at the rear of the air outlet 4 . Therefore, the air blown out from the upper air outlet 4 is restricted to be blown backward by the air outlet blade 19 and blown forward.

As described above, when the air conditioner 1 is powered on, the control unit 30A opens the outlet blades 19 by operating the operation start switch of the air conditioner 1 provided on the operation unit such as the remote controller 60 . And, according to the operation of the operation stop switch of the air conditioner 1 provided on the operation part, the air outlet vane 19 is closed by the control part 30A.

In addition, in the air outlets 4 on the left and right, a blade mechanism for changing the air outlet direction up and down by the blades 20 driven by the motor 17 to change the air outlet direction is provided on the back side of the air outlet blades 19 . The vanes 20 are composed of a plurality of plate-shaped vanes (six in the figure) arranged at approximately equal intervals in the longitudinal direction of the left and right air outlets 4, and each vane 20 is rotatably supported on the upper front panel 11B by a horizontal axis 21. state, connect one end with a longitudinal connecting rod 22. In this way, by driving the vertical connecting rod 22 up and down by the motor 17 (for example, by driving one blade 20 to drive the vertical connecting rod 22 in the vertical direction), each blade 20 changes the air outlet direction up and down.

Next, the driving of each blade 20 will be described. In the state where the power of the air conditioner 1 is turned on, if the operation start switch of the air conditioner 1 provided on the operation part such as the remote controller 60 is operated, the motor 12, the compressor of the outdoor unit 50, and the heat exchanger are started by the control part 30A. The air conditioner 1 is started to operate by the air blower 51 and the like. In this state, each blade 20 is substantially horizontal. In this state, each time the airflow direction switch is operated, the motor 17 rotates in a predetermined manner through the control unit 30A, and each blade 20 rotates upward or downward, so that the air outlet direction is changed to upward, horizontal, or downward.

This is accomplished, for example, by the following actions. That is, if the wind direction switch is activated once, the motor 17 will make a predetermined rotation, and each blade 20 will move upwards by one stage, so that the air outlet direction is upward. Next, if the wind direction switch is operated again, the motor 17 will rotate as specified, and each blade 20 will move downward one level, so that the air outlet direction is in a substantially horizontal state. Next, if the wind direction switch is operated again, the motor 17 will rotate as specified, and each blade 20 will move downward one level, so that the air outlet direction is downward. Then, if the wind direction switch is further operated once, the motor 17 will make a specified rotation, and each blade 20 will move upward one level, so that the air outlet direction is in a substantially horizontal state. In this way, the wind direction can be changed every time the wind direction switch is activated.

In addition, the structure may also be as follows: an automatic wind direction switch is provided on an operation part such as the remote controller 60, and by activating the automatic wind direction switch, the motor 17 is repeatedly rotated forward and reverse through the control part 30A, and each blade 20 is in the position of Continuous rotation in the up and down direction. At this time, the air outlet direction automatically changes in the up and down direction. The wind direction switch and the automatic wind direction switch can be configured separately, but they can also be integrated, and the operation parts of the manual wind direction and the automatic wind direction are provided on the operation parts such as the remote control 60 .

In addition, when the air conditioner 1 is started to operate, the set state of each blade 20 may be different in the cooling operation and the heating operation. For example, it may be in a substantially horizontal state during cooling operation, and may be in a downward direction during heating operation.

On the air passage formed in the air conditioner body 2 that communicates with the air inlet 3 and the air outlet 4, the air blower 6 is arranged behind the lower front panel 11A, and the heat exchanger is arranged behind the upper front panel 11B. The air blower 6 is configured to house a multi-blade fan 10 driven by a motor 12 in a fan case 9 having an air inlet 7 on the front and an air outlet 8 on the upper surface. The multi-blade fan 10 is a well-known structure in which a plurality of blades 10B are arranged circularly at equal intervals on the peripheral portion of a partition plate 10A, and the air sucked in from the front opening by rotation is blown out from the intervals between the plurality of blades 10B. The center portion of the partition plate 10A is recessed forward so that the motor 12 enters the multi-blade fan 10 , and the center of the partition plate 10A is coupled to the rotation shaft of the motor 12 at the recessed position.

The fan case 9 has a front wall on which the air inlet 7 is formed and left and right side walls extending left and right from the front wall, and has an opening on the back. The motor 12 is installed at a predetermined position on the rear wall 2B of the air conditioner body 2 through the mounting screws 14. In this state, the fan casing 9 is mounted on the rear wall 2B of the air conditioner body 2 via the heat insulating material 56 through the mounting screws 13. The specified position to block the rear opening. With this installation, the front opening of the multi-blade fan 10 is opposed to the air inlet 7 . The multi-bladed fan 10 rotates, and its front opening sucks in air from the air inlet 7, and blows out air from the intervals of multiple blades 10B to the surroundings. sent upwards. In addition, heat insulating materials 56 and 57 are attached to substantially the entire surfaces of the back surface of the rear wall 2B of the air conditioner main body 2 and the back surfaces of the left and right side walls.

As shown in FIG. 4 , the heat exchanger 5 adopts the method in which the refrigerant pipes 5B pass through the vertically long aluminum plate-shaped cooling fins 5A arranged at approximately equal intervals, and the air inflow surface is above the air outlet 8 of the fan case 9 . 1. Opposite to the air outlet 8 obliquely, the upper part of the heat exchanger 5 is arranged obliquely backward relative to the lower part, the upper part is close to or abuts against the rear wall 2B of the air conditioner body 2, and the lower part is close to the front opening of the air conditioner body 2 2A and set obliquely. Furthermore, the left and right width of the heat exchanger 5 is such that the left and right sides reach the vicinity of the left and right side walls of the air conditioner body 2, and in the orthographic projection state, the left and right width spans substantially the entire range of the upper front panel 11B. The purpose of this configuration is to obtain a wide heat exchange area.

In order to widely supply the air blown upward from the air outlet 8 of the fan unit 6 to the air inflow surface of the heat exchanger 5, the left and right width of the air outlet 8 of the fan case 9 is formed to be approximately close to the left and right width of the heat exchanger 5. size of.

An electrical equipment box 30 is attached to the mounting plate 29 straddling the left and right portions of the front opening 2A of the air conditioner main body 2 in front of the fan case 9 . The electrical equipment box 30 accommodates a power supply unit of the air conditioner 1 or a control unit 30A including electrical components such as printed circuit boards. Therefore, as shown in FIG. 5 and the like, the electrical equipment box 30 is provided in a state protruding forward from the air conditioner main body 2 .

On the front of the front wall 11B1 of the upper front panel 11B, a control panel 28 including a display unit for displaying the operating state of the air conditioner 1 by LEDs and a receiver unit for receiving infrared signals from the remote controller 60 is provided. Corresponding to the control panel unit 28, the control unit 27 electrically connected to the control unit 30A housed in the device box is mounted on the lower rear surface of the front wall 11B1 of the upper front panel 11B. In addition, instead of the remote controller 60 or used in combination with the remote controller 60 , an operation unit that operates the operation control unit 30A may be provided in parallel with the control panel unit 28 . The operation of the control unit 30A is performed by the operation of the remote control 60 or the operation unit instead of the remote control 60 , and the operation control of the air conditioner 1 is performed by the control unit 30A.

Because at the back of the front wall 11B1 of the upper front panel 11B, after the air passing through the heat exchanger 5 collides, it mainly splits to the left and right and upwards, and is blown out from the left and right air outlets 4 and the upper air outlet 4 respectively. Therefore, when the air conditioner 1 During the cooling operation, the front wall 11B1 of the upper front panel 11B is cooled, and dew may be formed on the front or back thereof. In order to prevent this phenomenon, a heat insulating material 26 such as foamed styrene is pasted on the back surface of the front wall 11B1.

However, in an environment with high humidity, when the air conditioner 1 performs cooling operation, dew may be formed on the surface of the heat insulating material 26 . The dew falls downward and wets the electrical equipment box 30 or other parts arranged behind the lower front panel 11A, and there is a risk of electric leakage. In addition, there is a possibility that the ground on which the air conditioner 1 is installed is wetted by flowing down.

In order to prevent the above-mentioned disadvantages caused by the generation of dew, the present invention is constituted as follows: between the front upper part of the fan casing 9 and the front panel 11 of the air conditioner 1, a heat sink is provided in the air conditioner body 2 to receive heat from the air. The water receiving pan 25 for the dew dripped from the exchanger 5 is extended to the front so as to receive the dew dripped from the back side of the upper front panel 11 . The front panel 11 has the left and right side walls extending rearward at the left and right ends of its front wall, and the water receiving tray 25 enters the space formed by the front wall and the left and right side walls of the front panel 11 at its front part, and can receive water from the front panel 11. The state of dew dripping down the back side.

If the above-mentioned situation is specifically described, as shown in the figure, when the front panel 11 is composed of a lower front panel 11A and an upper front panel 11B divided up and down, the lower front panel 11A and the upper front panel 11B respectively have left and right ends of the front wall. Extended left and right side walls. The front wall 11A1 of the lower front panel 11A is used as a decorative surface, and the air inlets 3 are formed on the left and right side walls. The front wall 11B1 of the upper front panel 11B is used as a decorative surface, and the air outlets 4 are formed on the left and right side walls 11B2. Furthermore, the upper front panel 11B has upper air outlets 4 formed on its upper wall.

Then, as shown in FIG. 9, the water receiving tray 25 is located at the upper end of the lower front panel 11A above the electrical equipment box 30, and is in a state extending forward, and its front part enters the front wall 11A1 of the lower front panel 11A. and the space formed by the left and right side walls 11A2. In order to introduce dew adhering to the back side of the upper front panel 11B into the drain pan 25 , a eave portion 31 is formed protruding upward from the lower portion of the upper front panel 11B to the upper side of the drain pan 25 . The eaves 31 are formed by bending the lower end of the front wall 11B1 of the upper front panel 11B, or are formed by being attached to the front wall 11B1, and are approximately provided across the range of the front wall 11B1 and the left and right side walls 11B2 of the upper front panel 11B.

With this structure, since the electrical equipment box 30 is disposed in the space below the water receiving tray 25, the dew dripping or falling from the back side of the upper front panel 11B can be received by the water receiving tray 25, and the above-mentioned problem can be solved. Under the water receiving tray 25, a heat insulating material 59 is pasted for heat insulation, so as to prevent the water receiving tray 25 from generating dew on the lower surface. Furthermore, since the left and right side walls of the water receiving pan 25 are in contact with the left and right side walls of the air conditioner main body 2, a heat insulating material 58 is pasted for heat insulation.

In order to conveniently carry out inspection, repair and wiring to the air supply device 6 or the electrical equipment box 30, and to clean or replace the filter installed on the back side of the air inlet 3, the lower front panel 11A can be easily detached. Installed on the air conditioner body 2, or supported on the air conditioner body 2 in an openable and closable manner. In the illustrated structure, one side end of the lower front panel 11A is closably supported on the air conditioner body 2 via the upper and lower hinge mechanisms 33 .

However, the upper front panel 11B constitutes a part of the air passage in order to realize the function of diverting the air passing through the heat exchanger 5 mainly to the left and right and upwards after colliding with it, and is therefore attached to it by fixing screws, locking claws, etc. The predetermined position of the air conditioner body 2 is not a structure that is frequently disassembled or opened and closed, but when the heat exchanger 5 is inspected, etc., it can be disassembled from the air conditioner body 2 by unscrewing its screws or the like. The structure shown in the figure is that a plurality of locking claws 11B3 extending rearward from the left and right side walls 11B2 of the upper front panel 11B are inserted into the locking holes 2A1 formed on the left and right flanges of the front opening of the air conditioner body 2, and Its lower end is locked, and the upper front panel 11B can be installed at a predetermined position of the front opening of the air conditioner body 2 .

As mentioned above, the water receiving tray 25 is located at the upper end of the lower front panel 11A above the electrical equipment box 30, and is in a state of extending forward, and its front part enters the front wall 11A1 and the left and right side walls of the lower front panel 11A. The space formed by 11A2. For this reason, its structure is: under the state of opening upper front panel 11B (comprising any one of the state of dismounting and opening and closing), since the upper opening of the water receiving tray 25 is in the front of the air conditioner body 2 Therefore, the inspection or cleaning of the water receiving tray 25 can be easily carried out from the front of the air conditioner body 2 .

In consideration of reducing the number of components and facilitating assembly, the water receiving tray 25 is integrally arranged with the fan casing 9 at the upper end of the fan casing 9 .

In the figure, the parts having the same functions as those in the first embodiment are marked with the same symbols, and since the description thereof is the same as that in the first embodiment, it is omitted here. Compared with Embodiment 1, the main difference between Embodiment 2 and Embodiment 1 is: an air outlet is formed on the front wall 11B1 of the upper front panel 11B, and the water receiving tray 25 is located at the bottom end of the upper front panel 11B and the bottom of the lower front panel 11A. The state of the space formed by the upper end. Specifically, its structure is: corresponding to the lower end portion of the upper front panel 11B and the upper end portion of the lower front panel 11A, the front portion of the water receiving tray 25 enters into a wall formed by each front wall 11B1, 11A1 and the left and right front walls 11B2, 11A2. In the state where the upper front panel 11B is opened, the drain pan 25 is in a state exposed in front of the air conditioner body 2 .

The above case will be described based on the diagram. On the upper part of the front wall 11B1 of the upper front panel 11B, the air outlet 4A is formed in a substantially rectangular shape, and in the air outlet 4A, a plurality of vertical vanes 35 are arranged side by side at the rear thereof, and a plurality of longitudinal blades 35 are arranged side by side at the front thereof. Transversal vanes 36 . The vertical vanes 35 are structured such that their upper and lower ends are supported by shafts 37 and are driven by a third motor 40 to change directions in the left and right directions. And the structure of transverse vane 36 is to be two groups of divisions up and down to form, and above a group of a plurality of transverse vanes 36A changes direction up and down by motor 38, and a group of a plurality of transverse vanes 36B then changes direction up and down by motor 39.

The effect of longitudinal vane 35 is to change the direction of the air blown out from air outlet 4A in the left and right direction, and its structure is, the longitudinal axis 37 of upper and lower end portion is rotatably supported on the upper and lower edge of support frame 45, and passes through the 3rd electric motor The drive of 40 changes direction in the left-right direction via the link mechanism 41 .

The longitudinal shaft 37 extending up and down from the upper and lower ends of each longitudinal vane 35 is rotatably supported on a support frame 45, and each longitudinal vane 35 has a link mechanism 41 so that all The longitudinal vanes 35 rotate in the same direction simultaneously. The structure illustrated as this embodiment is that when the longitudinal axis 37 of a longitudinal vane 35 (the longitudinal vane 35 at the far right end among FIGS. Therefore, each longitudinal vane 35 is connected together by an actuating plate 41B, and the actuating plate 41B is rotatably fitted on all longitudinal vanes 35 through a protrusion formed at a predetermined radius from the longitudinal axis 37.

Thus, through the operation of the left and right wind direction switch of the remote controller 60, due to the forward rotation and reverse rotation of the third motor 40, one longitudinal blade 35 rotates left and right, and along with this rotation, through the link mechanism 41, all other longitudinal blades 35 are also rotating left and right.

The function of the transverse vane 36 is to change the direction of the air blown out from the air outlet 4A in the up and down direction. The transverse shaft 44 extending transversely from the left and right ends through the central axis is rotatably supported on the left and right sides of the support frame 45, and the outlet The tuyeres 4A are divided into two groups vertically and substantially bisected.

In the above group of actuating structures, a plurality of (three in the figure) transverse blades 36A can change direction in the vertical direction through the link mechanism 42 as the first motor 38 mounted on the support frame 45 is driven. The illustrated structure of this embodiment is that because the transverse shaft 44 of a transverse vane 36A (the transverse shaft 44 of the second transverse vane 36A in the figure) is rotated by the first motor 38, it drives all other transverse vanes 36A Rotate similarly, so each transverse vane 36A is installed on the transverse shaft 44 on the opposite side of the first motor 38 at approximately right angles to the actuating arm 42A having a protrusion 42A1 protruding in the horizontal direction. The actuating plate 42B of the fitting part (hole or bearing part) 42B1 of each protruding part 42A1 connects each lateral blade 36A together.

As a result, one horizontal blade 36A is rotated vertically by the forward rotation and reverse rotation of the first motor 38 , and with this rotation, all the other horizontal blades 36A are similarly rotated vertically via the link mechanism 42 .

In addition, the actuation structure of the lower group is the same as that of the upper group, and the plurality of (three in the figure) transverse blades 36B of the lower group are driven by the second motor 39 installed on the support frame 45 through the link mechanism 43 , to change direction in the up-down direction. As the illustrated structure of this embodiment, because the transverse shaft 44 of a transverse vane 36B (the transverse shaft 44 of the second transverse vane 36B from the bottom of the figure) is driven by the second motor 39 when rotating all other transverse vanes 36B are the same Therefore, each transverse vane 36B is mounted on the transverse shaft 44 on the opposite side of the second motor 39 at approximately right angles to the actuating arm 43A having a protrusion 43A1 protruding in the horizontal direction. The actuating plate 43B of the fitting portion (hole or bearing portion) 43B1 of the protruding portion 43A1 connects the lateral blades 36B together.

As a result, one horizontal blade 36B is rotated vertically by the forward rotation and reverse rotation of the second motor 39 , and with this rotation, all the other horizontal blades 36B are similarly rotated vertically via the link mechanism 43 .

In addition, when each lateral blade 36A, 36B is a thin synthetic resin plate shape, the middle part may loosen downward. As a measure to prevent this phenomenon, an intermediate support member 46 installed in the vertical direction is provided in the middle of the upper and lower sides of the support frame 45 , and an intermediate support portion is provided on the intermediate support member 46 . In the embodiment, as the structure of the intermediate support portion, the intermediate support member 46 has the bearing portion 47 provided on the same axis as the lateral shaft 44, and the intermediate shaft 48 provided at the intermediate portion of each lateral blade 36A, 36B is supported by the bearing. The portion 47 is rotatably supported. In this way, the left and right ends and the middle part of each lateral blade 36A, 36B are supported by the bearing parts 44 and 47 provided on the same axis, so that the vertical rotation can be smoothly performed and the middle part can be prevented from sagging.

The motor 38 and the motor 39 can be controlled by the operation of the wind direction switch of the remote controller 60 . In the state where the power of the air conditioner 1 is turned on, the air conditioner 1 starts to operate by operating the operation/stop switch of the air conditioner 1 provided on the remote controller 60, and the motor 38 and the motor 39 are controlled by the control unit 30A so that Either the upper set of transverse vanes 36A or the lower set of transverse vanes 36B is set to a standby state, that is, a closed state, when the air conditioner 1 is stopped. In addition, in a state where the operation of the air conditioner 1 is stopped, the motor 40 is controlled by the control unit 30A so that the vertical blades 35 are vertically opened.

In the state where the air conditioner 1 is powered on, if the operation/stop switch of the air conditioner 1 provided on the operation part such as the remote controller 60 is operated, the motor 12, the compressor of the outdoor unit 50, and the heater are started by the control part 30A. The blower 51 etc. are exchanged, and the operation of the air conditioner 1 is started. In this state, each vane 36A, 36B opens downward (obliquely downward). In this state, every time the upwind direction switch of the remote controller 60 is operated, the motor 38 is controlled by the control unit 30A to perform predetermined rotation, so that the blades 36A are rotated horizontally, and the blowing direction of the air is changed to be horizontal.

This is accomplished, for example, by the following actions. That is, if the upwind direction switch is activated once for the upper group of transverse blades 36A, the upper group of motors 38 will rotate in the forward direction, and each blade 36A will move upward by one stage, so that the blowing direction of the air is horizontal. If the upwind direction switch is activated once again, the motor 38 will rotate in the forward direction, and each blade 36A will move upward by one stage, so that the blowing direction of the air is in an upward (obliquely upward) state. If the upwind direction switch is activated again, the motor 38 will rotate in the reverse direction, and each blade 36A will move downward by one level, so that the blowing direction of the air is horizontal. If the upwind direction switch is activated again, the motor 38 will rotate in the reverse direction, and each blade 36A will move downward by one stage, so that the blowing direction of the air is downward (obliquely downward). If the upwind direction switch is started again, the motor 38 of the upper group will rotate in the forward direction, and each blade 36A will move upwards one level, so that the blowing direction of the air is horizontal. The wind direction can be changed in turn by starting the upwind switch every time like this.

In addition, the same is true for the horizontal blades 36B of the lower group. If the leeward direction switch provided on the remote controller 60 is activated once, the motor 39 of the lower group will rotate in the forward direction, and each blade 36B will move upward by one stage, so that The blowing direction of the air is horizontal. Then, like the upper set of horizontal blades 36A, each blade 36B can be rotated to sequentially change the blowing direction of the air to the state of upward, horizontal, downward, horizontal, etc.

In addition, a full-automatic wind direction switch may also be provided on the operating parts such as the remote controller 60, and by activation of the fully automatic wind direction switch, the motors 38 and 39 are controlled to rotate forward and reverse repeatedly according to the mode set in the control part 30A. , so that the blades 36A and 36B can rotate continuously in the up and down direction to form various blowing directions. That is, the blades 36A and 36B are automatically and sequentially moved to the horizontal state, the upward state, the horizontal state, and the downward state at the same time.

Moreover, as another form, an upper automatic wind direction switch and a lower automatic wind direction switch may be provided on the operating parts such as the remote controller 60 . In this mode, the air conditioner 1 is started to operate, and the respective blades 36A and 36B are opened in a downward opening state (a diagonal downward opening state). In this state, the upper automatic wind direction switch is activated without operating the lower automatic wind direction switch, and only the blade 36A can repeatedly perform the actions of the horizontal state, the upward state, the horizontal state, the downward state, the horizontal state, and the upward state. At this time, the blade 36B remains in the downwardly opened state. In addition, without operating the upper automatic wind direction switch, but activating the lower automatic wind direction switch, only the blade 36B can repeatedly perform the actions of the horizontal state, the upward state, the horizontal state, the downward state, the horizontal state, and the upward state. At this time, the blade 36A remains in the downwardly opened state.

In addition, for the vertical blades 35, each time the left and right wind direction switch of the remote controller 60 is activated, the third motor 40 performs forward rotation and reverse rotation in sequence, and one vertical blade 35 rotates left and right. All the vertical blades 35 also rotate left and right, and the vertical blades 35 repeat the vertically opened state, the leftward state, the vertically opened state, and the rightward state according to a predetermined order, changing the blowing direction of the horizontal direction (left and right) of the air.

In addition, by the stop operation (start operation in the running state) of the operation/stop switch of the air conditioner 1 provided on the remote controller 60, the motors 38, 39 are controlled by the control unit 30A, so that the respective horizontal blades 36A, 36B are set to stand by. state, which is the closed state. And, by the stop operation (start operation in the running state) of the operation/stop switch of the air conditioner 1 provided on the remote controller 60, the motor 40 is controlled by the control part 30A to set each longitudinal blade 35 to a standby state, that is, to be vertical. open state.

A heat insulating material 26 such as foamed styrene is pasted on the back surface of the front wall 11B1 of the upper front panel 11B. The heat insulating material 26 is divided into a heat insulating material 26B around the air outlet 4A and a heat insulating material 26A below the air outlet 4A.

In order to introduce the dew attached to the back side into the drain pan 25 , a eaves portion 31 is integrally formed on the lower end portion of the lower heat insulating material 26A so as to protrude upward from the drain pan 25 . Since the left and right width of the heat insulating material 26A has a length spanning the left and right side walls 11B2 of the upper front panel 11B, the eaves 31 are also formed across the entire range of the left and right side walls 11B2 of the front panel 11B.
