Description

The present invention relates to a floor-standing air conditioner.

Floor-standing air conditioners generally used at home have a suction port on the front panel of the housing and an air outlet on the upper part of the housing, and convert the indoor air sucked from the front of the housing into cold air or hot air. It is designed to blow out from the upper part of the housing to cool or heat (see, for example, Patent Document 1).

FIG. 18 shows a floor-standing air conditioner described in Patent Document 1. The floor-standing air conditioner is provided with a suction port 103 on the front panel 102 of the housing 101 and an outlet 104 on the upper surface of the housing 101. The room air is sucked from the suction port 103 on the front surface of the housing, converted into cold air or warm air, and blown out from the air outlet 104 on the upper part of the housing 101 to perform indoor air conditioning.

However, since the conventional floor-standing air conditioner is provided with the suction port 103 on the front panel 102, the grill 105 of the suction port 103 is conspicuous, and the matching with the interior of the room is poor.

Therefore, the applicant has made the front panel a front panel having no suction port or having only a linearly elongated suction port, and providing an opening at least on the side surface of the housing so that air can be provided from the side surface of the housing. I am trying to make it a structure that sucks in.

The base members 24 and 24 that slidably hold the base members 24 and 24 in the front-rear direction are configured as main parts.

There are two left and right panel support members 23, 23, and arms 22a, 22b, 22c, and 22d are movably linked to the upper and lower portions of the panel support members 23, 23. In the linkage between the panel support members 23, 23 and the arms 22a, 22b, 22c, 22d, vertically long guide grooves 23b are provided in the upper and lower portions of the panel support members 23, 23, and the arms 22a, 22b are provided in the guide grooves 23b. , 22c, 22d by inserting pins 26 at the ends. The pair of upper and lower arms 22a and 22b, 22c and 22d of the panel support members 23 and 23 are connected by links 25 and 25, respectively.

The substantially central portion of the links 25 and 25 is held vertically by the base members 24 and 24 serving as the housing side members, and the panel support members 23 and 23 are the base member fitting portions 23a provided in the substantially central portion thereof. Is fitted to the base members 24, 24 and held so as to slide in the front-rear direction.

As a result, when the drive shaft 21a of the drive unit 21 rotates, the links 25 and 25 move up and down, and the arms 22a, 22b, 22c and 22d rotate accordingly, and the left and right panel support members 23 and 23 move back and forth. It will slide in the direction.

Here, the panel support members 23, 23 are detachably attached to both side portions of the front panel 6 so as to have a length extending substantially the entire length above and below the front panel 6.

Further, the panel support members 23, 23 on both the left and right sides are connected and integrated by a connecting shaft 28.

Further, the base members 24, 24 are attached to the side surface portion of the housing 2 by a screw or the like, whereby the entire panel driving means 12 is installed in the air suction opening 11 portion of the housing 2. That is, the panel driving means 12 is stored and installed between the front surface portion of the housing 2 and the front panel 6.

FIG. 15 is a control block diagram of a floor-standing air conditioner having the above configuration. This floor-standing air conditioner includes a control unit 31 that operates a blower 4 and a compressor 30 to control the overall air conditioning operation, a panel drive control unit 32, and a louver drive control unit 33. Then, the control unit 31 controls the entire harmonizer based on the operation instruction by the operation switch 34, and also obtains the output from the temperature detection unit 35, and the panel drive means 12 via the panel drive control unit 32 and the louver drive control unit 33. And the louver driving means 19, and the front panel 6 and the louvers 17 and 18 can be moved.

Next, the operation and operation / effect of the floor-standing air conditioner configured as described above will be described below.

First, to explain the operation, the floor-standing air conditioner of the present embodiment has the appearance as shown in FIGS. 1 and 2 when not in operation, and the front panel 6 covers the front portion of the housing 2. It has become.

In such a state, when the operation switch 34 is turned on S1 as shown in the control flow of FIG. 16, the control unit 31 opens the front panel 6 via the panel drive control unit 32 and drives the front panel 6 forward. Slide to move. As a result, an air suction gap 14 is formed between the outer peripheral portion of the front panel 6 and the front portion of the housing 2.

Next, the control unit 31 drives the louvers 17 and 18 via the louver drive control unit 33 S3, and opens and drives the two louvers 17 and 18 of the outlet 8.

After that, the compressor 30 for compressing the refrigerant is driven S4, and the blower 4 is also driven S5, and the indoor air is sucked into the housing 2 from both the air suction opening 11 and the air suction gap 14, and the heat exchanger 3 is used. It exchanges heat with the refrigerant and blows out from the air outlet 8 to cool or heat the room.

Cooling or heating is started as described above. For example, when the room temperature is higher than the set temperature (Y in S6) during cooling, the compressor 30 and the blower 4 are strongly S7, and the amount of movement of the front panel 6 forward is large. The angles of S8, louvers 17 and 18 are also set to large S9, and high-capacity operation S10 is performed. Then, when the room temperature reaches the set temperature (N of S6), the compressor and the blower 4 are switched to weak S11, the amount of forward movement of the front panel 6 is small S12, and the angles of the louvers 17 and 18 are also small S13. Capacity operation S14.

Then, when the operation switch 34 is turned off and there is an operation off signal (Y in S15) during the operation, the compressor 30 and the blower 4 are stopped together with S16 and S17 that close the front panel 6 and the louvers 17 and 18, and S18. S19, stop the air conditioning operation.

Next, the action and effect will be described.

As described above, in the floor-standing air conditioner of the present embodiment, the front panel 6 is located on the front side of the housing 2 and covers the front panel 6 during non-operation. Therefore, the appearance is flat, simple, and neat as can be understood from FIGS. 1 and 2, and the matching with the interior of the room is high.

In addition, the installation dimensions of the harmonizer in the front-rear direction are small. Therefore, the space in front of the harmonizer can be widely used. That is, the space in front of the harmonizer, which has been a problem peculiar to the floor-standing type, can be widened, and the usability can be improved.

On the other hand, in this floor-standing air conditioner, since the suction port 10 provided on the front panel 6 is linearly elongated and has a small opening area, there is a concern that air suction may be insufficient during operation.

However, in this floor-standing air conditioner, the front panel 6 moves forward during operation to form an air suction gap 14 between the outer peripheral portion of the front panel 6 and the front surface of the housing 2.

Therefore, even if the suction port 10 of the front panel 6 of the housing 2 is linearly elongated and small and air cannot be sucked in, air is sucked from the outer peripheral portion of the front panel 6 so that the air can be sucked into the housing 2. Can supply sufficient air and can be operated without worrying about lack of air. That is, it is possible to secure the amount of intake air while maintaining a flat, simple and neat appearance. In other words, it is possible to both simplify the design and ensure air conditioning performance.

In addition, in the present embodiment, a normally open type air suction opening 11 is separately provided on the side surface of the housing 2. Therefore, in addition to the air suction gap 14 formed between the front panel 6 and the housing 2, air is sucked from the normally open type air suction opening 11. Therefore, the amount of air sucked into the housing 2 becomes more sufficient, and it is possible to cope with an increase in capacity.

Moreover, by providing the normally open type air suction opening 11, an air suction gap 14 formed between the front panel 6 and the housing 2 is provided on the side surface of the housing. It can be made smaller by the area of the air suction opening 11 of the above. As a result, the amount of forward movement of the front panel 6 can be reduced.

Therefore, it is possible to secure the space in front of the harmonizer, which is a problem peculiar to the floor-standing type, that is, to secure a wide space in front of the harmony machine even during operation. That is, while ensuring the air suction performance during operation, the space in front of the harmonizer, which is a problem peculiar to the floor-standing type during non-operation and operation, can be widened, which makes it easy to use.

Further, since air is sucked from both the air suction gap 14 formed between the front panel 6 and the housing 2 and the normally open type air suction opening 11, the total air suction resistance is reduced. can do. Therefore, the driving power of the blower 4 can be reduced by that amount, and the energy saving property can be improved.

Since the air suction opening 11 is provided on the side surface of the housing, it does not have a great influence on the design and does not spoil the flat, simple and neat image when viewed from the front. Nor.

Further, in the present embodiment, the front panel 6 has a large moving amount of the front panel 6 when the room temperature is higher than the set temperature and is operated with a large capacity during cooling, and the room temperature is low and has a small capacity. When driving in, the amount of movement of the front panel 6 is reduced.

Therefore, the suction of air into the housing 2 can secure the amount of air required according to the driving ability in just proportion. Moreover, the amount of movement of the front panel 6 to the front can be minimized, and the space in front of the harmonizer during operation can be secured more effectively. That is, it is possible to secure a wider space in front of the harmonizer, which is a problem peculiar to the floor-standing type, while ensuring the air suction performance during operation, and it is possible to improve the usability.

In this example, capacity switching is described by switching between large and small stages for simplification, but the switching is not limited to this.

Next, the operation of the panel drive mechanism, which is a feature of the present invention, will be described. Since the floor-standing air conditioner of the present embodiment is a floor-standing air conditioner as described above, its front panel 6 is larger and heavier than the front panel of the wall-mounted air conditioner. Therefore, it is difficult to smoothly slide the front panel 6 forward.

However, in the panel driving means 12 of the present embodiment, the panel supporting members 23, 23 that are slid in the front-rear direction by the driving unit 21 have a length that extends substantially the entire length of the front panel 6.

Therefore, since the front panel 6 is held and driven by the panel support members 23, 23 up to both the upper and lower ends thereof, even a large and heavy panel can be smoothly slid and moved without rattling when driven by the electric motor 21b. be able to.

Further, the arms 22a, 22b, 22c, 22d that slide the panel support members 23, 23 in the front-rear direction are arranged on both the upper and lower portions of the panel support members 23, 23, respectively, and are movably linked with each other. The upper and lower arms 22a and 22b, 22c and 22d that drive the panel support members 23 and 23 are connected by links 25 and 25.

Therefore, the upper and lower arms 22a and 22b, 22c and 22d move back and forth in synchronization with each other by the connection by the links 25 and 25. As a result, the panel support members 23, 23 attached to the left and right side portions of the front panel 6 can move stably back and forth, and the front panel 6 can be driven in the front-back direction in a smooth and stable state.

Further, the panel support members 23, 23 on both the left and right sides are connected by a connecting shaft 28.

Therefore, even if the front panel 6 is wide, the surfaces at the left and right ends thereof are driven without being tilted in the opposite directions in the front-rear direction, so that the front panel 6 operates more smoothly and stably.

Further, the drive unit 21 is provided on any one of the arms 22a, 22b, 22c, and 22d, that is, the arm 22a for driving one of the left and right panel support members 23, and the arm 22a and the other panel support member 23 are provided. Is linked with the other arm 22c that drives the drive by an output shaft 27.

Therefore, the left and right arms 22a and 22b, 22c and 22d can drive the panel support members 23 and 23 by one drive unit 21, and the drives can be synchronized to facilitate the drive of the front panel 6. Can be. Moreover, it can be provided at low cost.

As described above, the floor-standing air conditioner of the present embodiment can smoothly drive the large and heavy front panel 6, but also has the following effects.

That is, in the floor-standing air conditioner of the present embodiment, the air suction gap 14a formed in the upper side portion of the panel by the movement of the front panel 6 is adjacent to the air outlet 8 provided in the upper part of the housing. As a result, there is a concern that a short circuit will occur in which a part of the air blown out from the air outlet 8 provided in the upper part of the housing is sucked from the air suction gap 14a formed on the upper side of the front panel 6, and the efficiency will decrease. Will be done.

Therefore, in the present embodiment, the lower end 16 of the air outlet 8 provided in the front corner portion of the housing 2 is configured to be located above the upper end edge 6a of the front panel 6 that has moved forward.

As a result, a step in the vertical direction is formed between the lower end 16 of the air outlet 8 and the upper end edge 6a of the front panel 6 that has moved forward, so that the air blown out from the air outlet 8 reaches the upper side portion of the front panel 6. It is possible to reduce or prevent a short circuit from being caught in the formed air suction gap 14a. As a result, it is possible to suppress a decrease in efficiency due to a short circuit, and it is possible to obtain a highly efficient floor-standing air conditioner.

Further, the front end of the lower end 16 of the air outlet 8 is located in front of the front end 14c of the gap edge of the air suction gap 14a.

As a result, the blown air from the outlet 8 is blown out from the front end 14c of the gap edge of the air suction gap 14a, and the probability that the blown air is caught in the air suction gap 14a and short-circuits is reduced. can do.

Further, in the air suction gap 14 formed in the outer peripheral portion of the front panel 6 moved forward, the suction resistance of the air suction gap 14a formed in the upper side portion of the front panel 6 is formed in the other side portion. It is configured to be larger than the suction resistance to be applied.

As a result, the air sucked from the air suction gap 14 formed in the outer peripheral portion of the front panel 6 is mainly sucked from the left and right side portions and the lower air suction gap 14. Therefore, the suction flow velocity of the air sucked from the air suction gap 14a on the upper side portion of the front panel 6 becomes slow, and the probability of entraining the blown air from the outlet 8 can be further reduced.

Further, in this floor-standing air conditioner, louvers 17 and 18 are provided on the upper surface and the front surface of the air outlet 8 of the housing 2, respectively, and each of the louvers 17 and 18 is cornered at the front corner portion of the housing 2. The front panel 6 is formed as a flat plate that forms a continuous flat surface with the front louver 17 while being butted in a shape.

As a result, the blowing direction of the blown air can be reliably changed by the two louvers 17 and 18 provided on the upper surface and the front surface of the blowout port 8. Moreover, since the front side portions of the two louvers 17 and 18 are butted in a square shape and the front panel 6 is a flat surface continuous with the front louver 18, the front surface of the harmonizer makes use of the flat feeling of the front panel 6 to be a harmonizer. The entire front surface can be made into a neat image with flatter corners, and the design can be more matched to the interior of the room.

The louvers 17 and 18 provided on the upper surface and the front surface of the outlet 8 are driven by the louver driving means 19 (see FIG. 15). When the louvers 17 and 18 are opened, the louvers 17 on the upper surface are first opened and then driven. The front louver 18 is openly driven.

FIG. 17 shows driving of the louvers 17 and 18 by the louver driving means 19, and when there is a louver open signal from the control unit 31 (Y in S21), the louver 17 on the upper surface is opened and driven S22. Then, when a predetermined time elapses, for example, 1 to 2 seconds elapses (Y in S23), the front louver 18 is opened and driven S24.

In this way, the louvers 17 and 18 provided on the upper surface and the front surface of the air outlet 8 open drive the louver 17 on the upper surface and then open drive the louver 18 on the front surface. Therefore, due to the operation interference that occurs when the louvers 18 are simultaneously opened and driven. It is possible to prevent malfunction. Therefore, even if the front corner portion of the air outlet 8 is square and has a neat appearance continuous with the front panel 6 and is a highly designed floor-standing air conditioner, the louvers 17 and 18 should be opened smoothly. Can be done.

On the contrary, when the louvers 17 and 18 are closed, that is, when there is a louver closing signal (Y in S25), the front louver 18 is first closed and driven S26. Then, when a predetermined time elapses, in this case about 1 to 2 seconds (Y in S27), the louver 17 on the upper surface is closed and driven S28.

As a result, it is possible to prevent malfunction due to operation interference that occurs when the louvers are closed and driven at the same time, and to close the louvers 17 and 18 smoothly as in the case of opening the louvers 17 and 18.

Further, the louver 17 provided on the upper surface of the air outlet 8 has a diffuser shape in which the lower surface thereof is on the same surface as the air passage 9 in the housing 2 when the louver is opened, and the tip portion blows out as an upward inclined surface 17a. It is configured to expand the flow of air.

As a result, the degree of change in the wind direction can be further increased while improving the ventilation efficiency, and even a floor-standing air conditioner installed at a low position can realize more comfortable air conditioning.

As described above, in the floor-standing air conditioner of the present embodiment, the housing 2 having the heat exchange function and the ventilation function, the front panel 6 covering the front surface of the housing 2, and the front panel 6 are moved forward. The panel driving means 12 is provided with a moving panel driving means 12, and the panel driving means 12 is rotated by a base member 24 attached to the housing side, a driving unit 21 having an electric motor 21b provided on the base member 24, and the driving unit 21. A panel support member that is movably linked to the driven arms 22a, 22b, 22c, 22d and the arms 22a, 22b, 22c, 22d and slides in the front-rear direction by the rotation of the arms 22a, 22b, 22c, 22d. 23 is provided, and the panel support member 23 is attached to the front panel 6 so as to have a length over substantially the entire length above and below the front panel.

As a result, the front panel 6 is supported and driven by one panel support member 23 up to both the upper and lower ends thereof, so that even a large and heavy panel can smoothly move back and forth without rattling when driven by the electric motor 21b. can do.
