Description

Air conditioner

The present invention relates to air conditioners.

In general, an air conditioner is a device that cools and heats the room or purifies the air using a refrigerant cycle consisting of a compressor, condenser, expansion device, and evaporator in order to create a more comfortable indoor environment for users.

The air conditioner can be broadly classified into a separate air conditioner in which the outdoor unit and the indoor unit are installed separately, and an integrated air conditioner in which the indoor unit and the outdoor unit are installed together in one cabinet.

Generally, in an integrated air conditioner, the indoor unit portion is placed toward the room with a wall or window in between, and the outdoor unit portion is disposed toward the outdoors. At this time, an indoor heat exchanger is installed in the indoor unit portion, and an outdoor heat exchanger is installed in the outdoor unit portion to form one refrigerant cycle.

In relation to the conventional integrated air conditioner, the present applicant has filed and registered a patent application (hereinafter referred to as Prior Document 1). The conventional integrated air conditioner according to the preceding document 1 was prepared with the indoor unit portion and the outdoor unit portion completely separated. Accordingly, air flow between the indoor unit portion and the outdoor unit portion was impossible. Therefore, there was no choice but to supply conditioned air indoors by inhaling only indoor air, and as a result, there was a problem in that it was difficult to purify the indoor air when it was polluted. In addition, there was a problem in which the air conditioner could not be operated effectively depending on the environment in which it was used.

In order to improve this problem, the present applicant has filed a patent application (hereinafter referred to as Prior Document 2). The conventional integrated air conditioner according to the preceding document 2 provides both an indoor unit part and an outdoor unit part, but there is a problem in that indoor air and outdoor air are mixed together by a single fan. Therefore, there was a problem of low thermal efficiency of the refrigeration system. Additionally, there was a problem with the air conditioning system taking up a lot of indoor space. In addition, since indoor exhaust cannot be performed on days when fine dust is severe, there was a problem in that air conditioning of the indoor environment could not be performed in the first place.

Prior Document 1: Republic of Korea Patent No. 10-1158124, integrated air conditioner Prior Document 2: Republic of Korea Patent Publication 10-2018-0082250, integrated air conditioner

The present invention is proposed against the background described above, and its purpose is to propose an air conditioner that can prevent mixing of indoor air and outdoor air during operation of the air conditioner.

The purpose of the present invention is to propose an air conditioner that can be used in various positions depending on the user's desired condition.

The purpose of the present invention is to propose an air conditioner that can exhaust only indoor air without being affected by outdoor air, even when both the outdoor and indoor environments are bad.

The purpose of the present invention is to propose an air conditioner that can improve heat exchange efficiency.

The air conditioner according to the present invention includes a case providing a body; An indoor facing surface that overlooks the indoor space; Outdoor facing side overlooking the outdoor space; an outdoor discharge portion provided on the outdoor facing surface to discharge air; and a hose mounting portion provided at the outdoor discharge portion into which the hose is inserted. According to this, a highly efficient air conditioner can be used even if the entire air conditioner is placed in an indoor space.

An outdoor side suction part is provided on the wall facing side of the case and sucks air, so a large space can be used as an air suction area.

An outdoor blocking film is further included to partition the outdoor suction part and the outdoor discharge part, so that the flow of air can be guided without mixing.

An open/closed door that can be freely opened and closed is provided to open and close the area of the outdoor discharge portion excluding the hose mounting portion, so that the discharge air of the air conditioner can be guided according to the installation state of the air conditioner.

The hose mounting portion is provided below the central portion of the outdoor discharge portion to reduce air flow resistance.

A connecting hose connected to the hose mounting portion; And a diffuser connected to the connection hose is included, thereby reducing the impact on the outdoor side.

At least a portion of the connecting hose is provided as a corrugated pipe, which can reduce the inconvenience of having to move and reinstall the connecting pipe when moving the air conditioner.

Foreign substances flowing in from the outside can be blocked by a check valve provided inside the diffuser to selectively block the movement of fluid.

The connection structure can be fixed by a discharge frame formed at the end of the diffuser and installed on the window frame.

At least a portion of the diffuser includes an expansion part that expands the air flow area from upstream to downstream based on the flow direction, so that a large space can be used on the indoor side and the obstruction due to air flow on the outdoor side can be reduced. .

According to the present invention, since the air conditioner can be used in an indoor space, mixing of indoor air and outdoor air does not occur, so there is an advantage that it can operate independently of each other.

Since the present invention can only exhaust indoor air and prevent outdoor air from flowing in, the air conditioner can be used more widely and diversely.

The present invention has the effect of improving the coefficient of performance of the refrigeration system because indoor air can increase the heat exchange efficiency of the outdoor heat exchanger during operation of the refrigeration system.

The present invention has the advantage of allowing users to feel more satisfied because it can be used while the air conditioner is mounted in an indoor space.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. However, the spirit of the present invention is not limited to the following examples, and a person skilled in the art who understands the spirit of the present invention will be able to easily suggest other embodiments within the scope of the same spirit, but this is also within the scope of the spirit of the present invention. It can be said to be included within.

In the following description, the air conditioner may be referred to as an air conditioner or air conditioner, but all of these refer to the air conditioner according to the embodiment.

1 is a diagram showing the installation state of an air conditioner according to an embodiment.

Referring to FIG. 1, the air conditioner 1 according to the embodiment may be installed on the window frame 2. The air conditioner (1) is divided into an inside and outside area by a window frame (2), and the indoor part placed on the indoor side and the outdoor part placed on the outdoor side are distinguished from each other. In the air conditioner, the indoor portion and the outdoor portion are provided in a single body. In the drawing, the left side can be divided into the indoor side and the right side can be divided into the outdoor side.

The air conditioner (1) may be placed and fixed on an installation frame (3), and the installation frame (3) may be fixed to the window frame (2). An extension plate (4) is provided on the upper side of the installation frame (3) to shield the empty space of the window frame that is not blocked by the installation frame (3).

An indoor suction port 13 and an indoor discharge port 14 are provided on the indoor side of the air conditioner 1. The indoor intake port 13 and the indoor discharge port 14 may be opened or covered by a door 16.

The indoor discharge port 14 may be placed above the indoor suction port 13. According to this, cooled air can be blown from a higher position, thereby improving user satisfaction.

Figure 2 is a diagram explaining the installation of an air conditioner in an embodiment.

Referring to FIG. 2, the air conditioner 1 is provided in the form of a cassette that is long in the vertical direction and short in the left and right directions, so that it can be installed by slightly opening the window frame 2. Accordingly, the space opened by the window can be minimized and cooling and heating losses can be reduced.

The external shape of the air conditioner 1 can be maintained by the case 15. The case 15 may include an indoor side facing surface 200 facing the indoor space, an outdoor side facing surface 300 facing the outdoor space, and wall facing surfaces 400 on both sides facing the wall. there is.

The installation frame 3 is provided with a placing frame 31 having a rectangular plate structure that fits the window frame 2, and an opening 33 provided inside the placing frame 31. An enclosure 32 is provided on the edge of the opening 33 and is in close contact with the air conditioner 1.

On the upper side of the installation frame 3, an extension plate 4 can be raised. The extension plate is provided in a corrugated structure that can be freely expanded and contracted, so that it can conveniently close the empty space on the upper side of the installation frame (3).

The boundary between the outdoor facing surface 300 and the indoor facing surface 200 is the highest point T, which is the highest point in the vertical direction of the case 2, and The lowest point (P) can be provided. The highest point (T) and the lowest point (P) can ensure that the installation position is well fixed after the air conditioner (1) is installed.

Explain in detail. The enclosure 32 may be provided to be convex outward of the opening 33. The highest point (T) and the lowest point (P) can be accommodated inside the enclosure 32. According to this, the inner and outer ends of the enclosure 32 are in contact with the indoor facing surface 200 and the outdoor facing surface 300, and the convex inner surface of the enclosure 32 is at the tight point T. And the lowest point (P) can be accommodated. Ultimately, the enclosure 32 may hold the air conditioner.

Preferably, the inner surface of the enclosure 32 can accommodate the highest point (T) and the lowest point (P) and maintain the same shape as the outer surface of the corresponding case 15.

Based on the highest point (T) and the lowest point (P), the indoor portion of the air conditioner has a smaller volume than the outdoor portion. As a result, the impact of the air conditioner 1 on the indoor space can be reduced, and the space invading the indoor space can be reduced. Users can use more indoor space.

The air conditioner of the embodiment may provide the indoor facing surface 200 and the outdoor facing surface 300 differently in order to provide an air conditioning environment even though the shape and configuration of the indoor side and the outdoor side are not the same as above. there is.

Specifically, the radius of curvature (R1) in the vertical direction of the indoor facing surface 200 may be provided to be larger than the radius of curvature (R2) in the vertical direction of the outdoor facing surface 300. The radius of curvature R3 in the left and right directions of the indoor facing surface 200 may be provided to be larger than the radius of curvature R4 in the left and right directions of the outdoor facing surface 300. According to this, the indoor facing surface can be flatter compared to the outdoor facing surface. The outdoor facing surface is provided with a small radius of curvature, so that more space is secured and many components can be accommodated therein.

In order to intake and discharge indoor air in a narrow space, the indoor facing surface 200 may suck in air from the sides and bottom of the indoor facing surface, and discharge conditioned air from the upper part of the indoor facing surface. In order to obtain sufficient air flow efficiency using a narrow installation space and a small indoor facing surface 200, the intake and discharge ports were placed on the same indoor facing surface 200 and their positions were differentiated.

A door 16 may be installed in front of the indoor facing surface 200. The door 16 can be moved downward when the air conditioner is operating so as not to act as flow resistance to the discharge action of the indoor discharge portion 14. The door 16 can block the user's access to each component that is tightly installed in the narrow space of the interior side.

Since the outdoor facing surface 300 can secure a large space, outdoor air can be sucked in from the wall facing surface 400 and outdoor air can be discharged through the outdoor facing surface 300. The wall facing surface 400 is the surface of the case 15 that faces the wall.

Figure 3 is a schematic vertical cross-sectional view of an air conditioner according to an embodiment.

Referring to FIG. 3, in the air conditioner, the internal space of the case 15 may be partitioned from each other by an indoor/outdoor barrier 141. The left side divided in the drawing may be the indoor side and the right side may be the outdoor side.

The indoor and outdoor sides of the air conditioner may be connected to each other by a refrigeration system. Specifically, the compressor 111 placed on the outdoor side compresses the refrigerant, the compressed refrigerant is condensed by the condenser 112, the condensed refrigerant is expanded by the expander 113, and the evaporator 114 placed on the indoor side. ) can be evaporated.

A condensation fan 115 blowing air to the condenser 112 and an evaporation fan 116 blowing air to the evaporator 114 may be further included. A filter 118 is provided on the upstream side of the evaporator 114 to ensure that air supplied indoors is supplied in a filtered state. It is preferable that the discharge side of the condensation fan 115 and the evaporation fan 116 is directly connected to the indoor space and the outdoor space. In other words, the heat-exchanged and filtered air can be sucked in by each fan and then discharged to the indoor and outdoor sides. According to this, air can be discharged indoors and outdoors without reducing the flow rate.

Here, all of the air used to condense the refrigerant in the condenser is discharged to the outdoor side, and all of the air used to evaporate the refrigerant in the evaporator is discharged to the indoor side.

Ducts 121 and 131 passing through the indoor/outdoor barrier 141 may be further included. In detail, the ventilation duct 121 is a duct through which outdoor air flowing from outdoors to indoors flows, and the exhaust duct 131 is a duct through which indoor air flowing out from indoors to outdoors flows.

The ventilation duct 121 may be provided with a ventilation fan 123 that causes a flow of ventilated air, and a ventilation damper 122 that can open or close the ventilation duct 121. The exhaust duct 131 may be provided with an exhaust fan 133 that causes a flow of exhausted air, and an exhaust damper 133 that can open or close the exhaust duct 121. Here, each fan and each damper can operate independently of each other.

The intake side of the ventilation duct 121 is provided as close to the outdoor facing surface 300 as possible to allow intake of pure outdoor air. The discharge side of the ventilation duct 121 is preferably placed on the inlet side of the evaporator 114 so that the ventilated air can be supplied into the room after being conditioned.

The intake side of the exhaust duct 131 is provided as close to the indoor facing surface 200 as possible to enable intake of pure indoor air. The discharge side of the exhaust duct 131 is preferably placed on the inlet side of the condenser 114 so that the exhausted air can be used for the heat exchange function of the condenser and then discharged outdoors. According to this, since the air exhausted from the room can be used for heat exchange in the condenser, the heat exchange efficiency of the condenser can be increased and the coefficient of performance can be increased.

According to the configuration of the air conditioner described above, various operation modes can be implemented as follows.

First, the operating state of the refrigeration system will be described.

The ventilation duct 121 can be closed using the ventilation damper 122, and the exhaust duct 131 can be closed using the exhaust damper 132. In this case, general cooling can be performed without mixing outdoor air and indoor air. The main point here is that there is no mixing of outdoor air and indoor air, so there is no decrease in cooling efficiency.

In another case, when the ventilation duct 121 is opened using the ventilation damper 122 and the exhaust duct 131 is closed using the exhaust damper 132, there is no discharge of indoor air and no discharge of outdoor air. Clean cooling with inflow only can be performed. The clean cooling can be performed when indoor air is at a satisfactory level, but only outdoor air is desired to be introduced for purposes such as oxygen supply. It can be performed when scent is supplied indoors for a special purpose for another purpose.

In another case, when the ventilation duct 121 is closed using the ventilation damper 122 and the exhaust duct 131 is opened using the exhaust damper 132, there is no inflow of outdoor air, and the indoor air Exhaust cooling with only air exhaust can be performed. The exhaust cooling may be performed solely for the purpose of exhausting indoor air when the outdoor air is bad due to fine dust, etc., even though exhausting the indoor air is necessary. For example, there is a lot of smoke in the kitchen, but there is a lot of fine dust in the outdoor air.

Meanwhile, in the case of exhaust cooling, low-temperature exhausted indoor air may be supplied to the suction side of the condenser 112. In this case, the heat exchange efficiency of the condenser can be improved.

In another case, when the ventilation duct 121 is opened using the ventilation damper 122 and the exhaust duct 131 is opened using the exhaust damper 132, outdoor air and indoor air are connected to each other. Circulating cooling can be individually supplied to different spaces. The circulation cooling can be performed when the indoor air is bad and the outdoor air is good. The point to note here is that since there is no mixing of outdoor air and indoor air, cooling efficiency does not decrease.

In the above description, when each damper is opened, the corresponding fan can be turned on. However, a natural ventilation structure can also be used. The same applies below.

Above, only the case of cooling was exemplified, but this case is not limited and the same can be applied to heating. In the case of the embodiment, the cooling system and the heating system may be implemented together by installing a four-way valve and switching between cooling and heating.

A state in which the refrigeration system is not operating will be described.

When the ventilation duct 121 is opened using the ventilation damper 122 and the exhaust duct 131 is closed using the exhaust damper 132, there is no exhaustion of indoor air and only inflow of outdoor air. Clean ventilation can be performed. The clean cooling can be performed when indoor air is at a satisfactory level, but only outdoor air is desired to be introduced for purposes such as oxygen supply. It can be performed when scent is supplied indoors for a special purpose for another purpose.

In another case, if the ventilation duct 121 is closed using the ventilation damper 122 and the exhaust duct 131 is opened using the exhaust damper 132, there is no inflow of outdoor air, and indoor air Exhaust ventilation with only emissions can be performed. The exhaust cooling may be performed solely for the purpose of exhausting indoor air when the outdoor air is bad due to fine dust, etc., even though exhausting the indoor air is necessary. For example, there is a lot of smoke in the kitchen, but there is a lot of fine dust in the outdoor air.

In another case, when the ventilation duct 121 is opened using the ventilation damper 122 and the exhaust duct 131 is opened using the exhaust damper 132, outdoor air and indoor air are connected to each other. Circulating ventilation can be individually supplied to different spaces. The circulation ventilation can be performed when the indoor air is bad and the outdoor air is good.

As seen in the above description, in the embodiment, the discharge air from the exhaust duct and the ventilation duct do not mix inside the air conditioner, so thermal efficiency can be improved. Since the discharge side of the exhaust duct can be blown with cold air for heat exchange of the condenser, the heat exchange efficiency of the condenser can be further improved.

In the embodiment, the discharge air from the exhaust duct and the ventilation duct do not mix within the air conditioner and may be supplied separately. According to this, users can perform more appropriate driving by looking at the air conditioning environment they want, not only the temperature, but also the air pollution level. Ultimately, user satisfaction can be further improved.

Figure 4 is a front perspective view of an air conditioner according to an embodiment, and Figure 5 is a rear perspective view of an air conditioner according to an embodiment. Here, the front is based on the indoor side.

Referring to FIGS. 4 and 5 , on the indoor facing surface 200 of the air conditioner 1 facing the indoor side, air may be sucked in from the side, and conditioned air may be discharged from the top. Air may be sucked in from the lower part of the indoor facing surface 200 and guided to the side.

In order to provide a wide suction and discharge structure without disturbing indoor residents, the indoor facing surface 200 is provided to be relatively flat. In order to obtain sufficient air flow efficiency in the planar structure, the intake and discharge ports were placed on the same indoor facing surface 200 and their positions were differentiated.

Since the internal parts of the air conditioner are visible from the indoor side and may threaten the user's safety, a door may be provided on the indoor facing surface 200. The door 16 can be translated downward when the air conditioner is operating so as not to act as flow resistance to the discharge action of the indoor discharge portion 14.

The outdoor facing surface 300 may be provided wide and large by reducing the radius of curvature in order to install a large number of components. Since a large space is provided on the outdoor side of the air conditioner, outdoor air can be sucked in from the wall facing surface 400, and heat-exchanged air can be discharged through the outdoor facing surface 300 facing the outdoor space.

FIGS. 6 and 7 are views showing the interior facing surface, where FIG. 6 is a view showing the structure with the door raised, and FIG. 7 is a view showing the direction of air flow with the door lowered.

Referring to Figures 6 and 7, an indoor suction part 13 is provided on both sides of the indoor facing surface 200, and an indoor discharge part 14 is provided on the upper side.

The door 16 is raised upward when the air conditioner is not in operation to prevent the user's hand from closing the inside of the air conditioner, and when the air conditioner is in operation, the flow of discharge air discharged to the indoor discharge unit 14 This can be done so as not to cause any interference.

The door 16 may be placed away from the indoor facing surface 200 so as not to interfere with the suction passage of the indoor suction part 13.

Figure 8 is a perspective view showing the driving part of the door.

Referring to FIG. 8, a step 161 protrudes rearward from the back of the door 16, and a rack 162 may be provided on the back of the step 161. The step 161 provides a predetermined gap between the door 16 and the indoor facing surface 200, thereby securing a suction passage.

A pinion 163 engaged with the rack 162 is further provided, and the pinion 164 may be connected to the drive shaft of the motor 164 to which it is coupled. The motor 164 may be supported on a support frame 165 that is fastened to a separate support such as a case 15 that is different from the door 16. A reducer is provided on the driving side of the motor 164 to reduce the rotational speed of the motor 164, and the torque of the motor can be amplified and transmitted to the pinion 163.

Ultimately, when the motor 16 is operated, the door 16 can be raised and lowered by the interaction between the pinion 163 and the rack 162.

In some cases, in order for the door 16 to protrude forward, a forward protruding structure that protrudes the support frame 165 forward may be further provided. The forward protruding structure may be intervened between the support frame 165 and the case 15 to cause the motor 164 itself to protrude forward.

Figures 9 to 11 are diagrams showing each driving mode implemented by the air conditioner. Figure 9 shows general cooling, Figure 10 shows exhaust cooling, and Figure 11 shows clean cooling.

Referring to FIG. 9, it can be seen that the indoor and outdoor sides of the air conditioner each perform heat exchange and operate for the temperature and humidity desired by the user.

Referring to FIG. 10, it can be seen that the indoor and outdoor sides of the air conditioner each perform heat exchange to operate for the temperature and humidity desired by the user. In addition, indoor air is exhausted to the outdoor side, and bad indoor air can be discharged to the outside by the exhausted air.

Referring to FIG. 11, it can be seen that the indoor and outdoor sides of the air conditioner each perform heat exchange to operate for the temperature and humidity desired by the user. In addition, it can be confirmed that outdoor air flows into the indoor side and clean air is supplied indoors.

9 to 11 are views showing each operation mode individually, and as already described, it has already been seen that more air conditioning modes can be provided by opening and closing the ducts 121 and 131.

In more detail, when the refrigeration system is not operating in FIG. 10, exhaust ventilation can be performed, and when the refrigeration system is not operating in FIG. 11, clean ventilation can be performed, and FIGS. 10 and 11 When operated together, circular cooling or circular ventilation can be performed.

Although the air conditioner of the embodiment has been described as being seated and fixed on the installation frame 3, a large load, such as a compressor, may be generated inside the air conditioner. In this case, there may be cases where the installation frame 3 alone cannot support the load.

Since the outdoor side of the air conditioner protrudes more toward the outdoor side than the indoor side, the center of gravity is biased, the installation frame 3 deteriorates, and there is a risk of it tipping over due to repeated use and impact.

In order to increase the stability of the installation of the air conditioner (1), a stand may be provided as a separate support structure on the outdoor side of the air conditioner (1).

Figure 12 is a front perspective view of the air conditioner, and Figure 13 is a bottom perspective view of the air conditioner. Figure 12 shows a state in which the stand is mounted, and Figure 13 shows a state in which the stand is not mounted.

Referring to Figures 12 and 13, an insertion hole 123 is provided in the lower part of the outdoor facing surface 300. The wall forming the insertion hole 123 is connected to the frame forming the case 15 and the air conditioner, and may be provided at a predetermined depth.

A portion of the pedestal 124 may be inserted into the insertion hole 123. The pedestal 124 is provided with a connecting leg 121 inserted into the insertion hole 123, and a bottom portion 122 at the lower end of the connecting leg 121. The bottom portion 122 extends left and right to not only support the weight of the air conditioner, but also prevent the air conditioner from tipping over to the left and right.

The upper end of the connecting bridge 121 is inserted into the insertion hole 123 and connected to the air conditioner, and the lower end of the connecting bridge 121 is integrated with the bottom 122 to prevent the air conditioner from falling.

Hereinafter, the operation of the ventilation duct and exhaust duct will be described in more detail.

FIGS. 14 and 15 are diagrams explaining the operation of a ventilation duct in an air conditioner according to an embodiment. FIG. 14 is a schematic horizontal cross-sectional view of the indoor side of the air conditioner, and FIG. 15 is a schematic vertical cross-sectional view of the indoor side of the air conditioner.

Referring to Figures 14 and 15, the ventilation duct 121 extends toward the indoor side by passing through the indoor/outdoor blocking film 141. The discharge end of the ventilation duct 121 is located upstream of the inlet end of the evaporator 114. Air introduced from outdoors through the ventilation duct 121 may undergo heat exchange through the evaporator 114.

The discharge air from the ventilation duct 121 and the indoor air may flow into the evaporator 114 together to perform heat exchange. After the introduced air passes through the evaporator 114, foreign substances can be filtered out of the air by the filter 148. The air with foreign substances filtered out and the air conditioned can be moved upward and discharged into the indoor space.

In order to discharge air from the upper part of the indoor facing surface 200, a flow guide (not shown) may be provided to guide the air discharged from the evaporation fan 116 upward. An indoor blocking film 142 may be provided to prevent the discharge wind discharged from the evaporation fan 116 and flowing to the indoor discharge unit 14 from mixing with the air flowing into the indoor suction unit 13. The indoor blocking film 142 may function to prevent air discharged from the ventilation duct 121 from mixing with the indoor discharge portion 14.

Through the indoor facing surface 200, indoor air may flow in from the lower part and both sides of the indoor facing surface 200. Through the indoor facing surface 200, indoor air flowing in from the room and discharge air from the ventilation duct 121 may be discharged together from the upper part of the indoor facing surface 200.

Figure 16 is a diagram explaining the operation of an exhaust duct in an air conditioner according to an embodiment, and is a schematic horizontal cross-sectional view of the outdoor side of the air conditioner.

Referring to FIG. 16, the exhaust duct 131 extends to the outdoor side by passing through the indoor/outdoor blocking film 141. The discharge end of the exhaust duct 131 is located upstream of the inlet end of the condenser 112. Air introduced from the room through the exhaust duct 131 may exchange heat through the condenser 112.

Since the indoor air discharged from the exhaust duct 131 is colder than the outdoor air, the heat exchange efficiency of the condenser 112 can be increased. According to this, it is possible to achieve the effect of recovering cold air that is discarded outdoors. Ultimately, the benefit of increased energy efficiency of air conditioners can be expected.

The discharge air from the exhaust duct 121 and the outdoor air may flow into the condenser 112 together to perform heat exchange. After passing through the condenser 112, it can be discharged outdoors.

An outdoor blocking film 143 may be provided between the outdoor suction part 11 and the condenser 112. The outdoor blocking film 143 allows the negative pressure applied through the condensation fan 115 to affect the outdoor suction unit 11 via the condenser 112. Therefore, the air in the outdoor intake unit 11 may pass through the condenser 112 and then be discharged outdoors.

The outdoor blocking film 143 divides the outdoor suction part and the outdoor discharge part and provides a path for providing negative pressure, thereby allowing the intake of outdoor air.

The air conditioner according to the embodiment is provided with an indoor and outdoor side integrated, making it easy to move. Using these advantages, the air conditioner of another embodiment has the advantage of being able to operate even when its entire body is placed in an indoor space.

An air conditioner according to another embodiment that can implement the above-described advantages will be described below. In describing other embodiments below, the same description is assumed to apply to the same parts as the original embodiment and the description is omitted.

Figure 17 is a rear perspective view of an air conditioner according to another embodiment.

Referring to FIG. 17, a hose mounting portion 301 is provided on the lower side of the outdoor facing surface 17 of the air conditioner 1 according to another embodiment. A hose having a predetermined flow path structure may be mounted on the hose mounting portion 301.

The inner space of the hose mounting portion 301 may be connected to the outlet of hot air discharged from the condenser 112. Therefore, hot wind can flow through the structure connected to the hose mounting portion 301.

The hose mounting portion 301 is provided at the lower part of the outdoor facing surface 17 to improve the appearance. An insertion hole 123 is formed on the lower side of the hose mounting portion 301, and the stand 124 can be mounted on the insertion hole 123. By the pedestal 124 fitted into the insertion hole 123, the air conditioner 1 can stand upright anywhere in the room. Accordingly, the user can conveniently move and position the air conditioner anywhere.

Figure 18 is a schematic horizontal cross-sectional view of the outdoor side of the air conditioner, and is a view viewed horizontally where the hose mounting portion 301 is located.

Referring to FIG. 18, a hose mounting portion 301 is provided at approximately the center of the outdoor discharge portion 12. The inside of the hose mounting portion 301 is open so that the discharge air of the condensation fan 115 can pass through. According to this, hot air condensed through the hose mounting portion 301 can be discharged.

A first opening/closing door 302 and a second opening/closing door 303 may be provided on both sides of the hose mounting portion 301. The opening and closing doors 302 and 303 can open and close areas other than the hose mounting portion 301 of the outdoor discharge portion 12.

When the doors 302 and 303 are opened, air can be discharged through the entire area of the outdoor discharge unit 12, including the hose mounting unit 301. In this case, it can be understood that the air conditioner is seated on the window.

When the opening/closing doors 302 and 303 are closed, other areas of the outdoor discharge portion 12 except for the hose mounting portion 301 are closed. In this case, it can be understood that the air conditioner is placed somewhere in the indoor space. Of course, in this case, it is preferable that a separate connection structure be mounted on the hose mounting portion 301 to guide the discharged air to the outdoors.

Figure 19 is a perspective view showing the configuration fixed to the hose mounting portion.

The air conditioner according to another embodiment is placed indoors, and needs to be configured to extract exhausted air generated during operation of the air conditioner or indoor bad air to the outdoors.

As a configuration that achieves this purpose, a connecting hose 400 that is inserted into the hose mounting portion 301 and allows air to flow therein, and a portion fastened to the connecting hose 400 to separate indoors and outdoors, which can be exemplified by a window frame. A diffuser 500 installed in is included.

The connection hose 400 includes a corrugated pipe 401 capable of elasticity and expandability, a suction side fastening end 403 provided at the suction end of the corrugated pipe 401, and a discharge end of the corrugated pipe 401. A discharge side fastening end 402 is included.

Since the corrugated pipe 401 can be gently bent, there is no difficulty in discharging air to the outdoors no matter where the user moves the air conditioner.

The suction side fastening end 403 is fastened to the hose mounting portion 301 to receive discharge air from the air conditioner, and the discharge side fastening end 402 is fastened to the diffuser (500) to receive discharge air from the air conditioner. It can be discharged outdoors.

The diffuser 500 has a hose connection part 504 connected to the connecting hose 400, an expansion part 503 whose internal area is expanded, and an outlet 502 to discharge air and is installed on a wall such as a window frame. A discharge frame 501 is included.

The hose connection part 504 is airtightly connected to the discharge side fastening end 402 to prevent air leakage.

The expansion portion 503 reduces the flow rate of air passing through the interior. According to this, when a large amount of air is discharged, the flow rate of the air can be reduced, the generation of noise resulting from this can be reduced, and the impact of high-temperature discharged air on the outdoor space can be reduced.

A grill is provided at the outlet 502 to prevent foreign substances from entering. The discharge frame 501 is a component to which the diffuser 500 is fastened, and as a representative example, it may be fixed to a small portion of a window frame. Comparing the case where the discharge frame 501 is installed on the window frame and the case where the air conditioner 1 is installed on the window frame, the installation area is greatly reduced, the effort of installation is reduced, and the damaged area of the window frame is reduced, and accordingly, It can be seen that the insulation efficiency can be increased.

A check valve 505 may be provided at any location inside the diffuser 500. The check valve 505 may be opened when the air conditioner is in operation and closed when the air conditioner is not in operation. According to this, it is possible to prevent foreign substances from entering from the outside and to prevent the air conditioner from being damaged by rainwater.

Figure 20 is a perspective view showing the installation state of an air conditioner according to another embodiment.

Referring to FIG. 20, the connecting hose 400 is inserted into the hose mounting portion 301 and the diffuser 500 so that discharge air can be guided. At this time, the relative positions of the diffuser 500 and the air conditioner 1 can be freely varied by the action of the corrugated pipe 401. In other words, the user can freely move the air conditioner to the desired location.

The discharge frame 501 occupies only a small area of the window frame 2 and can be installed. According to this, cold air loss through windows can be further prevented.

In order to prevent the air conditioner from tipping over when placed indoors, the stand 124 is mounted below the rear portion of the air conditioner. The bottom of the pedestal 124 is provided long to the left and right to prevent the air conditioner from tipping over.

According to the present invention, by improving the configuration of an integrated air conditioner installed in a window, the usability of indoor space can be further increased. In addition, thermal efficiency can be increased by separating indoor air and outdoor air rather than mixing them.

In addition, since the user can use the air conditioner according to the desired specifications in an indoor space, user satisfaction can be increased, so industrial application is greatly expected.

In addition, the air conditioner can be used conveniently in indoor spaces.
