Description of the invention (1) [Background of the invention] The present invention relates to an air conditioner, and in particular, to a lattice window provided with an air outlet for heat radiation of an outdoor unit. In recent years, in addition to air-conditioning and heating operations, dehumidification operation can be implemented according to the purpose of use. This has greatly improved performance. Along with the improvement of performance, high heat dissipation performance which can meet heat dissipation performance is required. In order to satisfy high heat dissipation, although it is necessary to increase the air volume of the cooling fan in the outdoor unit, there is a problem that noise is generated with the increase of the air volume. The air conditioner is a so-called separate type air conditioner which separates an outdoor unit from an outdoor unit. In this air conditioner, indoor and outdoor units are equipped with a fan for heat dissipation, or a fan for sending (blowing) cold air and heating to the room. These fans are expected to achieve high air volume and low noise. In particular, for the performance of a controllable air conditioner and the high wind quantification and low noise of a propeller fan adjacent to an outdoor unit that imparts noise The requirements are extremely high. Conventionally, as a structure for solving these requirements, there is, for example, Japanese Patent Laid-Open No. 0 7-3 0 5 8 6 9. This conventional technique is to improve a lattice window that blows out air in front of a propeller fan installed in an outdoor unit. This is a case in which a second grille is arranged on a first grille (lattice plate) constituting a lattice window mounted in a direction toward the air blown by a fan, with a predetermined gap therebetween. The shape of the first grid is formed to have a cross-sectional shape that reduces the thickness from the upstream side to the downstream side of the air grid, and the second grid is arranged from the grid with a gap therebetween. And the shape of the grille is the same as the first grille. The paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm). --- ΙΓ — — — — — — ----- --- ( Please read the precautions on the back first ^ write this page) Order ·-• Line · Printed by the Shellfish Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs-4-403825 A7 B7___ 5. Description of the invention (2) Those who have become wings. The basic structure of this conventional technology is to install the first grille and the second grille in front of the air outlet of the outdoor unit, to specify the direction of the blown wind, and to make the first blower to specify the blown wind direction. The shape of the grille and the second grille are wing-shaped, taking into consideration that the direction of the left and right winds of the fan shaft is different, and the twist pitch (pitch) of the left and right wings is changed. However, this conventional technology is to achieve a high air volume, high efficiency, and low noise of the fan. Therefore, it is necessary to configure the grille to have a two-layer structure, making it a complicated structure. In general, a fan protector is installed in front of a fan installed inside a frame constituting an outdoor unit for the sake of safety. The fan protector is composed of a plurality of flat horizontal (direction) grids arranged in the left-right direction of the frame. A plurality of vertical grids for reinforcing the horizontal grids are arranged on the flat horizontal grids toward the upper and lower sides of the frame. Printed by the Shelley Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, as described above, most of the grid windows composed of horizontal grids (mostly) are formed by horizontal grids. The position of the horizontal grids and the rotation position of the fans will cause the wind to blow out. Becoming different is well known. The wind direction drawn out of the frame by the horizontal grille can be roughly divided into 4 directions. For example, the upper lateral grille and the lower lateral grille that are substantially parallel to the fan rotation direction, and the right lateral grille and the left lateral grille that are approximately orthogonal (vertically intersecting) in the central lateral grille of the fan rotational direction. 4 directions. The angles blown out by the four directions are individually different. For example, when the grid window is divided into three in the up and down direction, the upper part of the paper size -5- applies to the Chinese National Standard (CNS) A4 (210 X 297 mm). Printed by Shelley Consumer Cooperative, Intellectual Property Bureau, Ministry of Economic Affairs a7 __B7 V. Description of the invention (3) The horizontal grille is approximately parallel to the rotation direction of the fan, so the sucked air will be spit out (exhaust) to the right. The horizontal grille in the lower part is substantially parallel to the rotation direction of the fan as in the upper part, so the air blown out will be blown to the left. On the other hand, in the central part, the horizontal grille forms an orthogonal position with respect to the rotation direction of the fan. Therefore, with the axis of the fan as the boundary line, it will be inclined toward the lower right direction or the upper left direction. In this way, the fan protector allows the discharged air to be individually ejected in different directions of up, down, left, and right directions. In particular, in the central part, the air from the fan collides with the flat horizontal grille from an oblique direction (slant), and on the back of the impacted surface, there will be separation of the air flow, so that the air velocity will be localized. The increase in physical formation causes pressure loss to increase, making it impossible to achieve high air volume and low noise. It is an object of the present invention to provide an air conditioner which can prevent air separation in a lateral grille and improve performance and attempt to mute by high air volume. The above-mentioned object is an air conditioner mainly including a refrigerating cycle that connects a compressor with a first heat exchanger and a second heat exchanger by a refrigerant pipe, and an outdoor space that houses the second heat exchanger and a fan. The frame of the unit and the frame facing the fan are equipped with a lattice window composed of a horizontal grille (lattice plate) and a vertical grille, which are characterized by: The airflow upstream side of the orthogonal (vertically intersecting) grille is curved to match the angle of the discharge (exhaust) of the air.

Printed by Shelley Consumer Cooperative, Intellectual Property Bureau, Ministry of Economic Affairs [Embodiment] FIG. 1 shows an embodiment of the present invention, which is a front view of the outdoor unit 1. In FIG. 1, the strong horizontal grille 3 is arranged roughly in the unit and at the wind blowing outlet 2. Although the fan shape of the wind blowing out circle is not shown, it is roughly the same as the fan 5 (to be described later ( Yes) The curvature protector grid 3 forms a deformer. A plurality of the curvature protection covers are arranged in the center (Y portion) in 5 directions. On the other hand, when the upper part 1 is rotated to the right, the curvature protection cover 5 will be orthogonal to each other. In the X and Z sections, the fan rotation directions are parallel. If the horizontal grille in the Y part of FIG. 1 is a flat horizontal grille 3, it comes from the surface of the horizontal grille 3, and the air flows smoothly from the oblique direction (inclined direction, although the air can imitate the impact surface). The ground flow, can be separated by the phenomenon of air flow, so that the separation surface is the outer diameter (hood) of the wide and square mouth shape from the wind in the longitudinal direction. It is parallel. However, it is equal to the imitation part. It makes the horizontal outer single up and down in the direction of rotation of the figure to form the wind term t (· | install I · order the same as the X and Z parts. ) Impact (collision), but the negative pressure on the back of the impact surface makes the horizontal paper size applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm) A7 B7 403825 V. Description of the invention (5) Direction The velocity of the flow between the grilles 3 increases rapidly, so that the flow path is lost. The curvature protection cover 5 of the present invention has the function of picking up the separated wind. Read the back. Note on the top Figure 2 is part A of Figure 1 Top view. In Figure 2, there is heat exchange in the outdoor unit 1. The fan 8 supports the fan motor (motor) downstream of the fan motor bracket 9. When the fan motor 10 rotates, the fan 14 having (fan) blades 11 starts to rotate to perform air supply. Downstream, the part with the wind blowing becomes the mouth ring 1 2 of the enlarged (enlarged) part 13, and a lattice window is arranged below the mouth ring 12. The outer diameter of the fan 14 is Part of the air will travel in the radial direction of the blades 11 and the axis of rotation will move in the up and down direction. At the outer diameter of the fan, the air between the horizontal grilles 3 will be blown out in parallel to the right in Figure 2 , And flows in the state where the air blown out from the shaft part rotates, so the curvature protection cover flows up and down at a great angle. And the angle between the curvature protection cover and the air blown out in the rotation state is matched and adjusted, and The lowermost area of the curvature protection cover 5 is flat, so the air will cause the rotating and high velocity air to decelerate on the downstream side of the curvature cover and travel straight in the direction of the fan's rotation axis. Figure 3 of the Consumer Property Cooperative of the Intellectual Property Bureau shows the cross-sectional view of Figure 1. In Figure 3, the direction of the wind is opposite to that of the cross-section of Figure A. Therefore, a curvature protection cover 5 should be provided near the rotation axis. The shape is configured to match the shape of the air flow (movement) from the bottom of Fig. 3. The curvature protection cover 5 can be arranged (10) for the upper and lower flat plate-shaped transverse grilles 3. Figure 4 Shows the state of the air flowing through the flat horizontal grid and the above embodiment. In Figure 4.1, the fan 14 with blades 11 will meet the Chinese National Standard (CNS) A4 specification (210 X 297). (Mm) -8- 403825 Α7 Β7 V. Description of the invention (6) Rotate towards the bottom of Figure 4. The blower outlet is provided with an orifice ring 1 2 and a blow-out enlarged portion 1 3, and a portion orthogonal to the direction in which the fan rotates and the long axis direction of the transverse grille 3 is arranged downstream. The curvature protection cover 5 is provided with a conventional flat-shaped horizontal grille 3 above and below the curvature protection cover 5. The state of air flow in the case of a conventional plate-shaped horizontal grid array will be shown in Fig. 4.2, and the state of air flow in the case of a curvature protection cover will be shown in Fig. 4.3. In any case, the central part of the transverse grille will be approximately orthogonal to the direction of travel of the fan. In the conventional lateral grille 3 in Fig. 4.2, when the (fan) blade 11 goes up and down in Fig. 4, the air flow from the blade 11 will flow at a relative outflow speed W2. Further, the peripheral velocity U2 of the blade 11 can be used to flow air into the flat horizontal grid 3 at the absolute velocity C2 of the blade from the part. At this time, the absolute outflow speed C 2 flows in at an angle which substantially forms an angle α 2 with respect to the front edge surface of the flat horizontal grille 3. The inflow angle α 2 flows in at about 30 to 45 degrees from the surface of the flat horizontal grille, and is spit out (exhausted) to the outside through the surface. However, the back of the flat horizontal grille is caused by air flow. The inflow angle is 30 to 45 degrees, which will cause the air flow to be separated at the front edge of the back side, and the flow path between the lateral grids after separation will be narrowed, resulting in a large increase in flow path loss. Because the flow path loss is proportional to the inflow speed at the front edge of the horizontal grille, it is possible that the reduced air volume caused by this loss may reach 15%. When the air flow is separated between the horizontal grilles, the air flow velocity will increase greatly, and noise will occur from the horizontal grilles and vertical grilles. This noise sometimes becomes louder than the sound generated by the fan itself.

Description of the invention (7) (Please read the precautions on the back 4 / write this page first.) Regarding the invention (have) Curvature (of) protection cover. Because the angle of the air flowing out of the fan is α 2, the leading edge of the curvature protection cover 5 is formed into an arc shape that can meet the outflow angle. At the same time, a flat horizontal grid is formed on the downstream side of the curvature protection cover 5. The grid is also flat in the axial direction. When the front edge of the curvature protection cover 5 is configured as shown in the figure, the angle of the air intrusion and the front edge of the curvature protection cover 5 will match (match). Therefore, at the back of the curvature protection cover, the air will flow as if crawling on the back, so that the air flow will not be separated. The air passing through the arc portion travels in a straight line toward the axis of the fan along the flat cover. Printed by Shelley Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, in more detail, the area of the flow path (flow channel) between the protective covers is caused by the air flowing from the fan into a rotating shape at the leading edge of the protective cover into which the air flows. S: It becomes small, and the air flow travels in a straight line at the trailing edge of the protective cover, so the area S 2 becomes large, so that the flow path loss between the protective covers is not increased, and the discharge speed of the air is reduced. This condition is formed by the well-known Bernolli theorem. When the air flow decelerates without loss, the static pressure will be restored and the air volume will be reduced (reduced). In addition, since no air separation occurs on the back of the curvature protection cover, it is possible to eliminate the occurrence of extremely high sounds due to the locally increased flow velocity between the protection covers (lattice plates). The effect described above will be shown in Fig. 5 in comparison with a flat horizontal grille. The effect is displayed on the horizontal axis as the rotation speed, and the vertical axis as the air volume and noise level. Both are based on the number of rotations, air volume, and noise levels at the point of use of the horizontal grille. In the above embodiment, although the air volume will increase by about 13% under the same number of rotations, the relevant noise level is only -10-. This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm). Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 403825 a7 _B7 V. Description of the invention (8) The effect of increasing by 0.8 d B only. Although not shown, the input of the fan motor is only increased by about 3%. 6 and 7 show other embodiments of the present invention. A partially enlarged protective cover of FIG. 6 is shown in FIG. 7. The part of the main grille that is orthogonal to, or approximately orthogonal to, the direction of travel of the fan is only a very limited number of the entire main grille. The front edge of the transverse grille, which has a distant part from a part orthogonal to the direction in which the fan travels, will be constituted in accordance with the outflow angle of the fan from the part. As for the angle of outflow of air, it is assumed to be approximately the same as the direction of the fan's rotation axis. When the curvature protection cover is used in this way, more than 50% of the horizontal grille can be matched to the air flow from the fan. In addition, although the angle of the outflow of air can be greatly changed by the diameter direction of the fan, the maximum effect can be obtained by designing the curvature protection cover in accordance with the flow angle of the part where the diameter of the fan is different, but sometimes When it is required to form a simple and pure curvature cover on the design pattern, it can also be designed to match the flow velocity of the fan's air outlet to a relatively large outer or inner part. Figures 8 and 9 show the present invention. Another embodiment. FIG. 9 is a partially enlarged view of FIG. 8. In FIG. 9, although the cross-sectional shape of the curvature protection cover which is orthogonal to or substantially orthogonal to the rotation direction of the fan is that the curvature near the front edge of the fan is used to change the flow of air, To make the thickness (width) of the outdoor unit thin, it is usually impossible to form a width that can sufficiently change the flow, so that it does not have the technical idea of being able to effectively turn the flow by a flat horizontal grid. Applicable to China Paper Standard (CNS) A4 specification (2) 0 X 297 mm for this paper size. -11- ---------- Packing !! I order ·! Line (Please read the precautions on the back &# Write this page) 403825 A7 B7 V. Description of the invention (9) This 'as a means to effectively change the flow by the depth (width) size of the flat horizontal grille' is constituted by the fan The front edge side of the flat horizontal grille that is impacted by the air becomes a grille with curvature, and the rear edge side is a grille with a curvature protection cover 5 that is straight or has a large radius of curvature. When configured in this manner, the air flow velocity through the protective cover can be made slow. FIG. 10 shows still another embodiment of the present invention. It is constituted so that the transverse grille which is orthogonal to or substantially orthogonal to the direction of rotation of the fan is made into a curvature protection cover 5 while the other parts are made into a conventional flat transverse grille or a large one. Protector of the radius of curvature. In the curvature protection cover, although the air flow needs to be changed sharply so that it is oriented toward the front side of the unit, but if the depth of the horizontal grille (width) in the direction is longer, the more effective turning can be achieved. . For this reason, the depth dimension of the horizontal grid which is orthogonal or substantially orthogonal to the rotation direction of the fan is lengthened. To grow, you can use any of Figures 10.1 and 10.2. When configured as such, it is possible to more effectively slow down the fast air from the fan. Furthermore, although the above description of the present invention has been described with a horizontal grille (lattice) as the main outdoor unit, even a vertical grille as the main outdoor unit may be suitable. The reason is that even if there is a horizontal grille or a vertical grille, if there is a grille that is approximately orthogonal to the direction of rotation of the fan, the same phenomenon will occur. According to the present invention, the separation of air passing through the horizontal grille can be prevented, thereby reducing the air flow velocity, so that it is possible to provide an intention to reduce the application of the Chinese National Standard (CNS) A4 specification (210 X 297 cm) at the horizontal paper size. --------- Install i I (Please read the notes on the back I write this page first "Order. --- Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs -12- 403 Thief 5 ___B7__ 5 Explanation of the invention (10) An air conditioner that generates noise and increases the amount of air to the grille.
