Description

  The present invention relates to an air conditioner, and more particularly to a configuration of a wind direction plate provided at an air outlet of an air conditioner.

  In recent years, air conditioners have been required to have a compact feeling when installed on a wall surface, replacing the conventional main body shape with a flat front surface and an elongated rectangular shape. It has become a deep shape. In addition, an increase in the amount of blown air has been demanded contrary to downsizing.

  For example, the air conditioner 30 shown in FIG. 6A suppresses the height dimension while forming the main body 31 with a shape having a depth in the front-rear direction and the amount of the blown air flow, in order to meet the above-described requirements. In order to cope with the increase, the front surface is formed into a smooth curved surface, and a large-sized air outlet 34 is provided at the lower part of the front surface.

  A front suction port 32 covered with a panel 42 is provided on the front surface of the main body 31, and an upper suction port 33 is provided on the upper surface. The above-described air outlet 34 is provided in the lower front portion of the main body 31, and the air outlet 34 has a plurality of left and right air direction plates (not shown) and an up and down air direction plate 40 formed in a curved shape so that one of them is a convex surface. The up-and-down wind direction plate 40 is rotated by the arm 41 to deflect the air blown out from the blow-out port 34 up and down, while rotating at an appropriate angle when the operation is stopped, and has a large diameter. The formed outlet 34 is closed (see Patent Document 1).

  A heat exchanger 35 and a blower fan 36 are provided in an air flow path connecting the front suction port 32 and the upper suction port 33 and the blower outlet 34, and the blower fan 36 and the blower outlet 34 Between them, there is provided a blow-out passage 37 composed of a front guider 38 on the upper surface and a rear guider 39 formed on the lower surface in a smooth curved shape. The indoor air sucked from the front suction port 32 and the upper surface suction port 33 is subjected to heat exchange by the heat exchanger 35, and then passes from the blower fan 36 through the blowout passage 37 to the room through the blowout port 34. It is sent again.

  Further, as shown in FIG. 6B, a drive mechanism 44 and a link mechanism 43 are provided on the front surface of the main body 31, and the panel 42 can be moved in the front-rear direction. When the panel 42 moves forward, indoor air is sucked from the front suction port 32 through the periphery of the panel 42, and when the panel 42 moves rearward, the front suction port 32 is closed. Furthermore, the lower surface of the panel 42 is closed by the extending member 45 at the intermediate position.

  During the cooling operation, the vertical wind direction plate 40 is driven by the arm 41, and as shown in FIG. 6B, the rear end portion is brought into contact with the front end portion of the rear guider 39. While being closed, the cold air 46 delivered from the outlet 34 is deflected with the concave surface facing upward in a horizontal state. The panel 42 is moved to the intermediate position described above, and the lower surface of the panel 42 is closed by the extending member 45 while sucking air from the front suction port 32.

The cold air 46 blown out from the outlet 34 is sent out to every corner of the room by being deflected in the horizontal direction or upward by the up-and-down air direction plate 40, and extending the panel 42. By closing the lower surface of the panel 42 with the outlet member 45, a phenomenon in which the cold air 46 deflected upward by the up-and-down wind direction plate 40 is sucked again from the front suction port 32, a so-called short circuit phenomenon occurs. I try not to. However, the provision of the extending member 45 not only complicates the structure of the air conditioner, but also increases the cost.
JP 2008-2777A

  The present invention provides an air conditioner having a smooth curved front surface and a large-diameter air outlet, which can close the large-diameter air outlet without any trouble when the operation is stopped without an extending member or the like. On the other hand, an object of the present invention is to provide an air conditioner including an up-and-down wind direction plate that can send out cool air in a horizontal direction without causing a short circuit phenomenon during cooling operation.

  In order to solve the above-mentioned problems, the present invention forms a smooth curved surface on the front surface of a main body provided with a suction port at least on the front surface and an air outlet provided with a vertical wind direction plate on the lower front surface. In an air conditioner comprising a heat exchanger and a blower fan in an air flow path connecting to the outlet, and a blowout passage continuing from the blower fan to the blower outlet, the vertical wind direction plate closes the blower outlet. In this case, the first bending portion is formed in the upper portion so as to have a curved shape that bulges to the front surface, and the second bending portion that is curved in the rear portion is formed in the lower portion. Further, during the cooling operation, the second bending portion is positioned on an extension line of the rear guider forming the lower surface of the blowout passage so as to be bent upward in contact with the rear guider, and the first bending portion is the first bending portion It has a configuration that is positioned lower than the two curved portions. Further, when the operation is stopped, the indoor bending light is reflected in a band shape by the second bending portion.

  According to the present invention, an upper and lower airflow direction plate is provided at the air outlet of the main body having a smooth curved front surface, and the upper and lower airflow direction plate is located above the air outlet when the air outlet is closed. The part extending from the edge part to the center part is formed in a curved shape that bulges forward and constitutes the first curved part, while being located on the lower side of the outlet and the part below the first curved part is By forming the second curved part that is concavely curved backward, the cooling air on the lower layer side that is guided by the rear guider that is the lower surface of the ventilation path during the cooling operation is an extension of the rear guideer and is smooth upward. The flow is guided forward by a second curved portion that is curved in a horizontal direction, and is sent out in the horizontal direction. In addition, the first bending portion is positioned at a position one step lower than the second bending portion, and the cold air on the lower layer side is positioned one step lower and is formed in a curved shape downward. It is sent to the horizontal direction without being wound up upward. Further, the cool air on the upper layer blown out from the outlet is attracted by the cool air on the lower layer side having a high flow velocity, and is sent out in the horizontal direction without going upward. As a result, the cold air blown out from the air outlet reaches every corner of the room without causing a short circuit phenomenon, and the indoor temperature is made uniform as much as possible to perform a comfortable cooling operation. Further, when the operation is stopped, the air outlet can be closed by the first curved portion of the up-and-down wind direction plate without causing a gap to the upper end of the air outlet. In addition, because the front surface is curved, the second curved part accentuates the lower part of the main body, which is shaded by the illumination light from the ceiling, reflecting the illumination light in a thin band shape, giving the air conditioner body a slim feeling. The interior can be improved.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail as examples based on the attached drawings.

  FIG. 1 is an external perspective view showing an air conditioner according to the present invention, and FIG. 2 is a sectional view thereof. 3A and 3B are a perspective view and a cross-sectional view showing the up-and-down wind direction plate, and FIG. 3C is a perspective view of a main part showing a lower front portion of the main body. 4A and 4B are explanatory diagrams showing the effect of the wind direction plate, and FIG. 5 is also an explanatory diagram showing the effect of the wind direction plate.

  As shown in the external perspective view of FIG. 1 and the cross-sectional view of FIG. 2, the air conditioner according to the present invention has a smooth curved surface on the front surface of the base 1 that is open on the front side and formed in a horizontally long rectangular shape. A front panel 2 is attached to constitute a main body. A front suction port 4 formed in a slit shape in the left-right direction is provided at the center of the front panel 2, and an upper suction port 3 made up of a plurality of horizontal rails is provided on the upper surface. Further, at the lower part of the front surface formed in a smooth curved surface, there is provided a large-diameter air outlet 5 provided with an up-and-down air direction plate 6 and a left and right air direction plate 13, and on the side thereof, a plurality of LEDs are formed. A display unit 7 and a receiving unit that receives signals from the remote controller are provided.

  As shown in FIG. 2, the air flow path connecting the upper surface suction port 3 and the front surface suction port 4 with the air outlet 5 is arranged in parallel with a filter 8 that removes dust in the sucked air. The heat exchanger 9 is composed of a fin and a heat transfer tube disposed so as to be orthogonal to the fin. The heat exchanger 9 includes a front lower portion 9a, a front upper portion 9b, and a rear upper portion 9c. A blower fan 11 is provided for sending the air again from the outlet 5 into the room. A front dew tray 10a for receiving and storing condensed water dripping from the front lower portion 9a and the front upper portion 9b is provided below the front lower portion 9a, and below the rear upper portion 9c. A rear dew tray 10b for receiving and storing condensed water dripping from the rear upper portion 9c is provided. Further, the upper side of the blowout passage connecting the blower fan 11 and the blower outlet 5 is made of a front guider 5a, and the lower side is made of a rear guider 5b formed in a smooth curved shape. The air sent out from the air is guided while being rectified by the front guider 5a and the rear guider 5b formed in a curved shape, and is blown into the room from the outlet 5.

  The vertical wind direction plate 6 provided in the blower outlet 5 is provided with a rib 6c at the lower part of the rear surface, and a shaft 6d protruding in the left-right direction from the rib 6c is pivotally supported on a stay 12 suspended from the upper wall of the blower outlet 5. When it is pivotally supported and rotated to a predetermined angle in the horizontal or oblique direction, it deflects the air that is blown out vertically, while it is flush with the main body when the operation is stopped. Further, the upper end of the outlet 5 is closed.

  Moreover, as shown in the perspective view of FIG. 3 (A) and the cross-sectional view of FIG. 3 (B), the up-and-down air direction plate 6 is formed to have an S-shaped cross section. When the shaft 6d of 6c is pivoted and the blower outlet 5 is closed, the part located on the upper side of the blower outlet 5 from the upper edge portion to the center portion and thereafter is a large radius (for example, R300 mm). While forming the curved first curved portion 6a that bulges forward, the portion located below the outlet 5 and below the first curved portion 6a is recessed backward by a small radius (for example, R30 mm). A curved second bending portion 6b is formed. Further, as shown in FIG. 3C, the air outlet side portion 2 a of the front panel 2 is also formed so as to coincide with the cross-sectional shape of the vertical wind direction plate 6. Compared to a conventional air conditioner, the blower outlet 5 having a large diameter is closed without a gap at the upper end by the first curved part 6a formed in a curved shape when the operation is stopped. Can be done.

  Next, the operation of the up-and-down wind direction plate 6 during the cooling operation will be described. At the start of the cooling operation, the blower fan 11 rotates at the maximum output so as to reach the set room temperature in a short time, and vigorously sends out the air exchanged by the heat exchanger 9. As shown in FIG. 4 (A), the up-and-down wind direction plate 6 rotates obliquely downward with the vicinity of the tip of the rear guider 5b as a center, and is guided by this, and the cool air urges downward from the outlet 5 It is often sent out indoors.

  Here, the room temperature is detected by a temperature sensor (not shown), and when the detected room temperature approaches a preset temperature, the blower fan 11 is controlled by a control unit (not shown) so that the rotation speed is reduced from the maximum output. Accordingly, the vertical wind direction plate 6 is controlled to rotate to a predetermined angular position. In this state, as shown in FIG. 4B, the second bending portion 6b is located on a virtual extension line indicated by a two-dot chain line of the rear guider 5b so as to extend the rear guider 5b. The one curved portion 6a is curved downward and is positioned below the second curved portion 6b, and the tip of the rear guider 5b and the tip of the second curved portion 6b are smooth. It is supposed to be connected to.

  The cool air 14a on the lower layer side, which is sent out from the blower fan 11 and guided by the rear guider 5b serving as the lower surface of the air passage, has a high flow velocity, as shown in FIG. The curved portion 6b is blown out on an extension line of the rear guider 5b. The cool air 14a on the lower layer side that has passed through the second curved portion 6b flows into the first curved portion 6a located at a lower position than the second curved portion 6b, and the flow is deflected in the horizontal direction without going upward, while It is sent out from the air outlet 5. Further, the upper layer side cool air 14b blown out from the front guider 5a side is attracted to the lower layer side cool air 14a and is sent out in the horizontal direction. Thereby, the air blown out from the blower outlet 5 is wound upward, and the short circuit phenomenon sucked in again from the suction inlet 4 can be prevented as much as possible. As shown in FIG. 6B of the conventional example, when the up-and-down wind direction plate 40 is formed in a curved shape that is simply recessed downward, the air blown out from the air outlet 34 has a curved shape that goes upward along the shape. As a preventive measure, the extension member 45 is necessary to prevent a short circuit phenomenon. However, in the configuration of the present application, the phenomenon in which cold air is directed upward is suppressed as much as possible without providing an extension member or the like. This eliminates the need for an extra mechanism, simplifies the structure, and reduces costs. In addition, it reaches the corners of the room directly under the air conditioner and prevents the cold air from directly touching the user's skin, making the indoor temperature as uniform as possible and enabling comfortable cooling operation. Yes.

  Next, the effect of the up-and-down wind direction plate 6 when the operation is stopped will be described. As shown in the external perspective view of FIG. 5, when the air conditioner is installed on a wall surface and illuminated from a lighting device such as a fluorescent lamp provided on the ceiling surface, the front surface is formed into a smooth curved surface. The upper surface portion of the panel 2 reflects light from the luminaire in a wide range, and a second curved portion 6b curved backward with a small radius of the up-and-down wind direction plate 6 and a backward curved portion at the lower portion of the main body which becomes a shadow of the illumination light. When the blower outlet side portion 2a of the front panel 2 reflects light, it looks like a thin strip. Traditionally it becomes a shadow part, the part that gave a heavy impression reflects the light and looks like a thin band, it becomes an accent, so that the air conditioner body can be slim and improve the interior It has become.

  As described above, the air outlet 5 having a large diameter is provided in the lower part of the main body formed with a smooth curved surface on the front surface, and the first curved portion is formed in the air outlet 5 in a curved shape bulging forward. The rear guider 5b is extended by the second curved portion 6b during cooling operation by providing an up-and-down airflow direction plate 6 that is formed in a curved shape that is recessed backward by a small radius and 6a. The cold air blown out from the blowout port 5 is sent out as an extension line of the rear guider 5b, and further, the first curved portion 6a formed in a downwardly curved shape does not cause a short circuit phenomenon. It is sent out horizontally and downward. As a result, the cold air blown out from the outlet reaches every corner of the room, and the indoor temperature is made uniform as much as possible to perform a comfortable cooling operation. Further, when the operation is stopped, the first curved portion 6a can close the outlet 5 having a large diameter without generating a gap at the upper end. In addition, because the front surface is curved, the second curved part reflects the illumination light at the bottom of the main body, which is shaded by the illumination light from the ceiling, and accentuates by showing it as a thin band, making the air conditioner main body slim. And can improve the interior.
