Description

Air Conditioner {AIR CONDITIONER}

The present invention relates to an air conditioner, and more particularly, a scroll housing is disposed at a right angle with respect to the front side of the case to improve the flow of discharged air, as well as to reduce the width of the air conditioner which is usually installed at an indoor corner. It is a slim air conditioner that is less constrained by location.

In general, the air conditioner is a device for controlling the temperature and humidity of the air by using the heat transfer generated during the evaporation and condensation of the refrigerant. An air conditioner represented by an air conditioner operates apparatuses such as a compressor, a condenser, an expansion valve, and an evaporator to circulate a refrigerant, and maintains a room temperature comfortably by using the latent heat of evaporation of the refrigerant.

Looking at this in more detail, when the compressor compresses the refrigerant to increase the pressure of the refrigerant to the saturation pressure, the condenser absorbs the heat of the high-pressure refrigerant to liquefy the refrigerant. The liquefied refrigerant is reduced in pressure by the throttling action of the expansion valve, and the refrigerant is evaporated in the evaporator to exchange heat with the indoor air to keep the room temperature comfortable.

The air conditioner is divided into separate type and integrated type according to whether to install a mechanical device such as a compressor as a separate outdoor unit, and the separate type air conditioner is subdivided into a stand type installed on the floor of the room and a wall type installed on the indoor wall. can do. The air conditioner is larger in capacity than the wall-mounted air conditioner, allowing air conditioning in a large indoor space.

As disclosed in Korean Patent Application No. 2006-0087637, the air conditioner is provided with a structure in which air sucked through an intake port is accelerated through a scroll housing having a blower fan, accelerated, passed through a heat exchanger, and discharged to a discharge port.

The air sucked into the air conditioner is rotated and accelerated inside the scroll housing. As the air rotates and accelerates, the flow of air discharged from the scroll housing is closely related to the direction of the air outlet of the scroll housing. That is, the air discharged from the air outlet is rotated and accelerated in the scroll housing and discharged with direction in a specific direction by the generated centrifugal force.

However, in the related art, since the scroll housing is installed in parallel with the front portion of the air conditioner, the scroll housing air outlet port faces the side of the air conditioner. That is, the scroll housing is positioned so that the air conditioner (Cut Off), which is the point of time of the air outlet, is disposed in a direction perpendicular to the front surface of the air conditioner. Therefore, the flow of the discharged air is biased to the left or right side of the air conditioner, so that it is difficult to control the airflow for cooling and heating, and there is a problem in that a separate control device must be added to change the flow of air.

In addition, conventionally, since the scroll housing is installed in parallel with the front portion, the width is larger than the thickness of the air conditioner. Therefore, when the air conditioner is installed in the corner of the room there is a problem that can not be in close contact with the wall waste space.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of an air conditioner according to a first embodiment of the present invention, FIG. 2 is a perspective view of a portion of a scroll housing and a heat exchanger, and FIG. 3 is a side view of a portion of a scroll housing and a heat exchanger of FIG.

As shown in these figures, the air conditioner 10 according to the first embodiment of the present invention has a scroll having a case 20 provided with a discharge port 36, an air inlet 42 and an air outlet 44. And housing 40.

The case 20 forms the appearance of the air conditioner 10. Inside the case 20, various accessories for operating the air conditioner 10 are built in. The case 20 is divided into a front face 22, a rear face 24, and a side face 26.

The front surface 22 is a portion in which an operation unit (not shown), a discharge port 36, and the like of the air conditioner 10 are provided. The front face 22 is usually provided in a flat shape, and various decorations may be added to enhance the appearance.

The rear face 24 is the rear part of the air conditioner 10. In the present invention, since the position of the scroll housing 40, which is conventionally positioned side by side with respect to the front surface 22, is changed by 90 degrees and is installed in a direction perpendicular to the front surface 22, the rear surface of the scroll housing 40 is accommodated. The center part of 24 protrudes compared with the edge part. The width (W of FIG. 4) of the air conditioner 10 is reduced in proportion to the position of the scroll housing 40 so that the center portion of the rear surface 24 protrudes. On the other hand, in the case of the front surface 22 is provided with a plate-shaped heat exchanger 50 and the like, there is a limit to the extent that the width (W in Fig. 4) is reduced, the width of the rear surface 24 (Fig. 4 compared with the front surface 22) The effect of W) is reduced more. Since the width (W of FIG. 4) of the air conditioner 10 is reduced and the center portion of the rear surface 24 protrudes, the air conditioner 10 takes up less space when the air conditioner 10 is installed at the corner.

The side surface 26 is a part in which the discharge port 36 of the air conditioner 10 is provided. The discharge port 36 protrudes outward when used, and folds out when not used, to have a beautiful appearance.

The scroll housing 40 accelerates and discharges the air by rotating the sucked air according to the shape of the scroll housing 40. Air inlets 42 are provided at both sides of the scroll housing 40, and air outlets 44 are formed above the scroll housing 40. The scroll housing 40 is disposed such that the air inlet 42 is positioned in a direction perpendicular to the front surface 22 of the case 20. In other words, the cut-off (Cut Off, 46), which is the point where the air outlet 44 starts in the scroll housing 40, is positioned side by side with respect to the front surface 22 of the case 20, or the blower 70 It means that the axis 72 of the case 20 is to be positioned side by side with respect to the front face 22 of the case (20).

Since the scroll housing 40 is disposed in the front-rear direction of the case 20 perpendicular to the front face 22, the width (W in FIG. 4) is reduced as compared with the case where the scroll housing 40 is conventionally positioned side by side with respect to the front face 22. . Although the thickness (T in FIG. 4) increases somewhat compared to the width (W in FIG. 4), the wall width is reduced by the reduced width (W in FIG. 4) when the air conditioner 10 is installed at the corner portion. Close contact can reduce wasted space. That is, the scroll housing 40 may be installed such that the scroll housing 40 is parallel to the front surface 22 of the case 20 in the thickness direction and at right angles in the width direction. When installed in such a structure, the air inlet 42 flows air in both side surfaces, and the air outlet 44 discharges air in the upper direction of the case rather than in the upper side of the case 20.

In addition, due to the scroll housing 40 arranged in the front-rear direction, the direction of the air discharged from the scroll housing 40 becomes constant with respect to the heat exchanger 50. Specifically, in the conventional case, since the scroll housing 40 is disposed side by side with respect to the front surface 22, the left or right side of the air conditioner 10 is rotated by centrifugal force at the moment of being rotated and accelerated air is discharged. A flow of air is deflected in the direction. When the air is deflected, the air discharged through the discharge port 36 of the air conditioner 10 also becomes the airflow deflected toward one of the left or right directions (F3 of FIG. 4), and thus, does not provide smooth air conditioning for the entire indoor space. . In addition, the heat exchanger 50 is also generally installed in a direction parallel to the front surface 22, in which case the air outlet 44 of the scroll housing 40 does not discharge air toward the heat exchanger 50, but instead heats it. Since the heat is discharged in a direction parallel to the front surface 22 of the machine 50, the heat exchange performance is inferior.

In the present invention, since the scroll housing 40 is disposed in the front-rear direction of the case 10, the phenomenon that the air discharged from the scroll housing 40 is deflected to the left or the right of the air conditioner 10 does not occur. Therefore, it is easy to control the air flow to evenly distribute the air discharged through the discharge port 36 of the air conditioner 10 throughout the indoor space. In addition, since the air which is not deflected to the heat exchanger 50 is discharged toward the heat exchanger 50, the heat exchange performance is improved and the heat exchange is uniform.

The sucked air is accelerated by the rotation of the blower 70 and discharged through the air outlet 44 provided above the blower 70. The air outlet 44 is a portion in which the accelerated air is discharged into the scroll housing 40. Since the scroll housing 40 is disposed in the front-rear direction of the case 10 and the air is deflected to the left or the right, it is not accelerated so that the air discharged through the air outlet 44 is not deflected and is directed toward the heat exchanger 50.

Air outlet 44 is preferably provided at a predetermined angle (α) of 5 degrees to 6 degrees in the direction of the heat exchanger 50 with respect to the rear surface 24 of the air conditioner (10). When the air outlet 44 is formed upward without a certain angle α, the air discharged from the air outlet 44 is concentrated on the upper side of the heat exchanger 50 due to the strong centrifugal force. Therefore, when the air volume of the air passing through the heat exchanger 50 is measured, as shown by F1, the air volume of the upper side of the heat exchanger 50 is larger than the average, while the lower side of the heat exchanger 50 is smaller than the average air volume. The imbalances that occur appear. On the contrary, when the air outlet 44 is formed to have a predetermined angle α toward the heat exchanger 50, the air discharged from the air outlet 44 is relatively supplied to the lower side of the heat exchanger 50. do. Therefore, when the air volume of the air passing through the heat exchanger 50 is measured, it can be seen that a relatively constant air volume appears from the upper side to the lower side of the heat exchanger 50 as shown by F2.

As described above, air discharged to the air outlet 44 is sucked through the air inlet 42, and the filter 60 is provided at the air inlet 42.

The filter 60 is provided in each of the air inlets 42 provided on the left and right sides of the scroll housing 40. Since the filter 60 is provided in each air inlet 42, the area of the filter 60 is increased and the purification ability is improved. In addition, the filter 60 may be easily replaced only by opening the door (not shown) provided on the front surface 22 of the case 20 and pulling the filter 60 forward.

The effect of the air conditioner according to the first embodiment of the present invention by such a configuration will be described below with reference to FIGS. 4 and 5.

4 is a diagram illustrating an installation of the air conditioner of FIG. 1, and FIG. 5 is a graph illustrating the performance of the air conditioner of FIG. 1.

As shown in FIG. 4, since the air conditioner 10 according to the first embodiment of the present invention installs the scroll housing (40 in FIG. 2) in a direction perpendicular to the front face 22, the conventional air conditioner The width (W) is reduced compared to the base (dotted line), and the extent to which the width (W) is reduced is larger than the front surface (22). Since the width W is reduced, when the air conditioner 10 is installed at the corner portion C of the room, the air conditioner 10 can be installed closer to the corner portion C. Therefore, the space required for the installation of the air conditioner 10 is reduced, which enables effective space use.

In addition, since the scroll housing (40 in FIG. 2) is provided in the direction perpendicular to the front face 22, the air flow F4 of the air discharged from the air conditioner 10 becomes constant. Conventional air conditioner (dotted line) is a scroll housing (40 in FIG. 2) is installed side by side with the front 22 rotates along the scroll housing (40 in FIG. 2) and the discharged air flows deflected toward one direction (F3 ) Is generated. A separate control device is required to correct the deflected airflow F3. On the contrary, the air conditioner 10 of the present invention can constantly discharge the air flow F4 to a desired position due to the position of the scroll housing (40 in FIG. 2) perpendicular to the front surface 22.

On the other hand, Figure 5 is a graph showing the performance of the air conditioner of the present invention. The vertical axis of the graph represents the dust collection capacity. As shown in the graph, it can be seen that the air conditioner (B) of the present invention improves about four times the dust collection capacity compared to the conventional air conditioner (A). Such a difference in dust collection capability is caused by an air inlet (42 in FIG. 2) provided on the left and right sides of the scroll housing (40 in FIG. 2) and a filter (60 in FIG. 2) respectively provided therein. That is, the area of the air inlet (42 in FIG. 2) is larger than in the prior art, and since the filters (60 in FIG. 2) are provided respectively, the resistance generated through the filter (60 in FIG. 2) is reduced, resulting in the collection capacity. It can be intuitively recognized that a difference will occur, and this recognition is supported by experiments.

6 and 7 are side views of a part of the scroll housing and the heat exchanger of the air conditioner according to the second and third embodiments of the present invention, and only those parts different from the first embodiment of the present invention will be described. In this case, the same parts as in the first embodiment will be cited with the same reference numerals, and the changed parts will be cited with the same reference numerals with the addition of 'a' or 'b'.

As shown in FIG. 6, the air conditioner according to the second embodiment of the present invention is provided with a guide plate 80a for guiding the air discharged from the air outlet 44 to the heat exchanger 50. The guide plate 80a is provided with a guide protrusion 82a protruding toward the heat exchanger 50. The guide protrusion 82a of the second embodiment is formed such that the guide plate 80a is bent to form a sharp angle.

The guide plate 80a provided with the guide protrusion 82a guides the air discharged from the air outlet 44 of the scroll housing 40 to the lower side of the heat exchanger 50. Therefore, since the air is not concentrated toward the upper side of the heat exchanger 50, the air passing through the heat exchanger 50 achieves a uniform air flow amount from the upper side to the lower side of the heat exchanger 50.

As shown in FIG. 7, the air conditioner according to the third embodiment of the present invention is formed with a guide curve 82b having a smooth curve.

FIG. 8 is a perspective view of an air conditioner according to a fourth embodiment of the present invention, and only parts different from the first embodiment of the present invention will be described. Citations shall be made by designating a reference, and reference to an altered part shall be given by giving a reference sign with the addition of 'c'.

As shown in the drawing, the air conditioner 10c according to the fourth embodiment of the present invention is provided with a front discharge port 34c in addition to the side discharge port 36 installed on the side surface 26.

The front discharge port 34c is provided on the front surface 22c of the case 20c and has a longitudinal shape. Since the scroll housing (40 in FIG. 2) is provided in the front-rear direction of the case 20c, the airflow F5 of the air discharged from the front discharge port 34c is not the airflow F6, F7 deflected left or right. Naturally towards the front of 22c). Therefore, it is possible to install the vertically long front discharge port 34c without adding a separate device to prevent the air flow (F5) of the air deflection, the cost-saving effect and the beautiful appearance that is distinguished from other products The air conditioner 10c can be designed to be visible.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and changes can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to be belong to the claims of the present invention.
